Hollyland Solidcom M1 as Designated Event Intercom System at Prolight + Sound Guangzhou (PLSG) 2022

Shenzhen, China, March 25, 2022 – The 20th edition of Prolight + Sound Guangzhou (PLSG), known as the largest entertainment and pro AV trade fair in China, was successfully held from February 25 to 28, 2022, in Area A & B of China Import and Export Fair Complex, covering 16 thematic halls spanning 160,000sqm.

With co-organizer Messe Frankfurt offering the dedicated digital platform - PLSG Live and Online - along with the physical show, the fair received present and online attention globally with more than 1,400 exhibitors.

Aiming to foster communication and collaboration across the direct and vertical markets, all while offering an immersive audio-visual visiting experience for visitors, the PLSG organizer had formulated the unique "PLS Xtage" theme event held in Hall 12.2.

The PLS Xtage hall ground was built into a multi-functional stage for performers to deliver an immersive audio-visual feast and offer a whole new interactive entertainment experience for the audiences.

Effective communication and cooperation of the line-up were critical to ensuring efficient preparation and execution of this grand event. For this purpose, the PLS team had designated Hollyland Solidcom M1 as the major team communication solution for the event. Two cascaded sets of this flagship wireless intercom system were deployed on-site. The PLS crew also invited the Hollyland team to provide technical support for the smooth operations on-and-off stage throughout the event.

Cascade Connection via a Network Cable or XLR Cable

The two Solidcom M1 sets at PLS Xtage were cascaded via a standard network cable of 328ft (100m). With the FRP antennas installed, the systems endowed an extended overall communication range in a 360° radius while enabling simultaneous team conversations involving up to 16 members.

To add more options and flexibility for the crew, each Solidcom M1 base station can cascade with multiple third-party systems using network cables or XLR cables via 2-Wire, 4-Wire, or two POE/LAN cascading interfaces.

Intuitive Grouping up to 3 Groups

The line-up at PLS Xtage included multiple parties, and small groups focused on different assignments for the same goal. The Solidcom M1's easy grouping operation came in handy, especially for the director group in allocating tasks and messages to each team, which significantly improved coordination efficiency as crew members busied around different sectors at the scene.

Enhanced Audio Quality

Adopting self-developed Noise-Cancellation Algorithms and a super-wide frequency response from 200Hz to 7KHz, the Solidcom M1 delivers authentic and astonishing sound at a broadcast-level sampling rate. During peak times of the event, when music, people's chattering, and noises fill the place, the LEMO dynamic headsets saved the day with clear exchanges of teammates' voice messages and easy microphone status control.

Summary

Solidcom M1 is a good fit for medium to large events ranging from 100 to 1000 guests. The standard package comes with eight beltpacks, each equipped with two removable and rechargeable Li-ion batteries, facilitating extended working hours whenever needed.

As Mr. Hongbo Jiang, Director of Guangdong International Science and Technology Cooperation Centre, said, "By delivering new show content together with sourcing, networking and educational opportunities at the highest level, we hope to provide the industry with the support it needs.” The Hollyland team is proud to contribute to such events.

Technical Principle, Product Characteristics, and Application of Wireless Video Transmission(2022年12月02日)

HOLLYLAND — 2022-12-02T17:46:45+0900

https://www.hollyland-tech.com/

In today's digital information age, social development, economic growth, and people's production are increasingly inseparable from the Internet and the application of various scientific and technological means. Various forms of wireless transmission functions are applied in different industries. And wireless video transmission technology has become an essential part in film and television productions. It is a wireless monitoring system that realizes the integrated transmission of sound, digital, and video data using radio waves as the transmission medium. What are its own advantages and principles?

1. Principles of the wireless video transmission system

A wireless video transmission system refers to a monitoring system that uses radio waves to transmit video, sound, data, and other signals without wiring (cables). These devices are very easy to setup and use on-site, free from the constraints of wired connections. At the same time, with the development of wireless technology, it has now been able to ensure the basic requirements of most film and television shooting teams for signal stability and real-time audio and video transmission and has gradually replaced wired transmission equipment with excellent user experience and cost performance.

2. Characteristics and applications of wireless video transmission system

1) Stable performance with low cost

Free from the hassle of wiring, wireless video transmission is no longer restricted by wires and cables, making the preparation work easier and more efficient, and allowing the cameraman to move around on the shooting site with more flexibility and freedom. The WiFi-enabled technology guarantees multi-party real-time monitoring via the mobile APP, which greatly facilitates team collaboration and efficiency. Wireless video transmission equipment with high cost-effectiveness and good performance on the market, such as Mars 400s pro and Mars 300 Pro system of Hollyland, are compatible with SDI and HDMI interface connections at the same time. An investment of less than $1,000 can meet the video transmission needs of most film crews for daily shooting.

2) Features and advantages of wireless AV transmission in film and television applications

● Real-time transmission

Both WiFi and WHDI technologies are widely used in video transmission. WHDI technology, an industry benchmark for wireless video transmission, provides a high-quality, uncompressed wireless connection. Systems that adopt the MIMO technology and OFDM modulation method can achieve a transmission rate of up to 3Gbps. Transmitting with no latency, and no compression in a carrier-grade also makes it expensive, with prices for the technology typically reaching over $2,000 on the market.
However, solutions using WiFi or other wireless signal frequency band transmission technologies are less expensive. Products using WiFi transmission technology are compatible with mobile devices for multi-party monitoring. Although the anti-interference performance is not as good as that of WHDI devices, they generally transmit with less than 0.1s latency that can meet the basic monitoring requirements of the crew's work, making them more cost-effective.

The application of different technologies brings a wide range of options to the user. In large-scale and high-investment film and TV production projects, where real-time monitoring and precise capturing is strictly required, the WHDI solution would be a more suitable choice for teams with sufficient budgets.

The better wireless video transmission products adopting WiFi or radio frequency transceiving technologies on the market can realize video and audio transmission with a delay of less than 0.08s, and some even reaching a delay of less than 0.04s, which can basically meet the requirements of shooting and focus pulling. And they are widely accepted by small crews and individual creators in their daily shoots.

● High-definition video quality

Solutions using WHDI technology can reach the specifications of 4K60fps, and WiFi or other radio frequency transceiving systems can generally reach the specifications of 1080p60fps. For most production teams, resolution up to 1080p is clear enough and more cost-effective for on-site monitoring, especially if taking into account the capacity of the monitors that production teams generally use.

● Coherence

For video transmission solutions with physical wired connections, the realtimeness and steadiness in their performance is the major advantage. But we are also very excited to discover that wireless video transmission has also made breakthroughs in this area. Recently, we have noticed that Hollyland's Cosmo C1 boasting its industry-first HEVO technology pioneered the integration of automatic frequency hopping and retransmission mechanisms that achieve a smooth monitoring experience without a black screen with a latency of less than 0.04s. As technologies in the industry continues to evolve, wireless video solutions are gradually approaching or rivaling wired devices in terms of real-time and coherence.

● Integration

With the rapid development of the Internet and the continuous increase in the scale of netizens, the online live broadcast industry has continued to develop in recent years with more individual creators engaged in this video content productions. Developers are constantly exploring the potentials and innovations in the endeavor of bettering the complicated and once cumbersome workflows in film productions. We have observed that some manufacturers have begun to integrate technologies such as video capture and codec into video transmission system equipment, providing more diverse and cost-effective integrated solutions for various types of shooting projects.

Compared with the traditional video capture method, the video stream of the video transmission is obtained through the video capture card, or the video stream of the image transmission system is obtained through the RTSP protocol. We have noticed that there are new video transmission technologies on the market that has the UVC protocol directly embedded on the transceiving device, namely, a direct livestreaming can be achieved by connecting the device with the computer only via a USB cable, without any external capture cards or other equipment. Its higher integration and lower cost of accessories make it more convenient and economical in practical applications.

Nowadays, the development of network technology has changed people's production and work habits in all aspects. The development of wireless technology is widely accepted and applied by more and more industries. The wireless video transmission system is an outcome of the continuous renewal and development of science and technology. Maybe many people are unfamiliar with this type of equipment, however, in fact, it has been used in all walks of life. For example, monitoring and Bluetooth are related to wireless transmission devices.

Radio interference in a wireless walkie-talkie system refers to electromagnetic waves that enter wireless communication devices through direct or indirect coupling. Radio interference will directly affect the reception of available signals, reducing its performance, deteriorating signal quality, causing communication blockage, increased transmission data errors or even loss. Common interference phenomena include co-channel , adjacent frequency, out-of-band and intermodulation interference.

1. Interference factor in the wireless intercom system: adjacent frequency interference

When the wireless signal is in the radio frequency band or near the passband of the receiver, the interference caused by entering the intermediate frequency band after frequency conversion becomes adjacent frequency interference. And this kind of interference will also reduce the signal ratio of the receiver and reduce the sensitivity, but it is different from co-channel interference. The adjacent frequency interference is mainly due to the technical indicators of the wireless communication equipment itself not conforming to the national technical standards. Adjacent channel interference can also occur if the receiver's IF filter performance is poor.

Another situation is that when the user leaves the station, the radio wave of one channel received by the base station is strong, and the radio wave of another channel may affect the quality of the wireless intercom system itself.

2. Interference factor in the wireles intercom system: intermodulation interference

Two or more signals are adjusted in a nonlinear transmission circuit to generate a combined frequency close to the same available signal frequency, thereby interfering with the wireless intercom system, which is intermodulation interference.

Transmitter intermodulation, receiver intermodulation, and intermodulation are three reasons cause external effects.

Intermodulation interference should satisfy three conditions at the same time:
(1) There is a certain spacing relationship between several interfering frequencies and the nominal frequency of the interfering receiver;
(2) The interfering signal should have a sufficient range;
(3) All jammers and jammer receivers should work simultaneously.

Transmitter intermodulation refers to the coupling of two transmitters to each other to form interference. Receiver intermodulation means that when two or more strong interfering signals enter the front-end circuit of the receiver, due to their nonlinear effects, the interfering signals are mixed with each other, resulting in intermodulation products that can fall into the passband of the receiver. Its size depends on factors such as the size of the interfering signal. Intermodulation caused by external effects refers to the poor contact between the transmitter's high-frequency filter and antenna fasteners or the phase interference of metal components, which can be avoided as much as possible.

3. Interference factor in the wireless intercom system: out-of-band interference

Out-of-band interference refers to the wireless interference caused by the spurious radiation of the transmitter of wireless communication equipment and the spurious response of the receiver. And this is also a common interference problem affecting wireless communication caused by the poor quality of the wireless intercom system itself.

Crystal oscillators are mainly used in transmitters of ultra-short wave radios to obtain higher frequency stability. The oscillator is multiplied to obtain the desired operating frequency. If the frequency multiplier of the transmitter has poor filtering characteristics, spurious radiation waves are generated at the transmitter output stage, which can interfere with the receiver at that frequency.

Spurious response of the receiver: In addition to receiving available signals, the receiver will also receive unwanted signals of other frequencies. This responsiveness to other unwanted signals has become the receiver's spurious response, which is related to the frequency purity of the receiver itself. Both stray radiation and stray response are strictly regulated in relevant national standards, and manufacturers should design products according to this index. In the production process, the quality control of the products should also be strictly sured, and the products that pass the inspection can be launched on the market.

In fact, the essence of wireless intercom system interference is electromagnetic interference. Therefore, in order to solve this problem, we should understand and analyze electromagnetic interference to find available methods to protect wireless walkie-talkies, while taking into account the relevant measures of electromagnetic compatibility.

What Are the Precautions for Purchasing Wireless Video Transmission Equipment?(2022年12月02日)

HOLLYLAND — 2022-12-02T17:45:42+0900

Wireless video transmission refers to a monitoring system that uses radio waves to transmit video, sound, data, and other signals without wiring (cables). Wireless image transmission (real-time video transmission) mainly has two concepts: one is mobile transmission, that is, mobile communication; the other is broadband transmission, that is, broadband communication.

To be able to shoot commercials, most businesses use wireless video transmission equipment. But many people don't know how to purchase this kind of equipment, and some people who are not familiar with this kind of equipment think they can just buy one, as long as it can transmit video. However, this opinion is not correct, and here we will show you how to purchase this type of video transmission system equipment.

1. The chip of the wireless video transmission system

If you want to know whether the wireless video transmission equipment is good or not, the best way is to understand the chip problem of the equipment. Because the effect of video transmission will be affected by the device chip, as long as you buy a high-quality chip, you can avoid this situation. It also means that when purchasing equipment, it is incorrect if you just pay attention to the low-price. You must choose equipment with high-quality chips, to ensure the effect of video transmission.

2. The speed of wireless video transmission

Video transmission takes time, but the time for video transmission is different for different devices. If you want to ensure work efficiency, you must choose a device with a faster video transmission speed. Otherwise, the work of the enterprise will definitely be affected. It is necessary to know that the video transmission speed of some devices is very slow.

3. The clarity of wireless video transmission

In the process of video transmission, it will be interfered with by the signal, which may lead to the reduction of the definition of video transmission or even damage. Therefore, it is recommended that you pay attention to this problem when purchasing equipment. If the effect of video transmission is poor, the filmed things cannot be used at all, which will only waste the time of the enterprise.

How could you purchase wireless video transmission system equipment? Pay more attention to the above 3 aspects, only in this way can you buy high-quality equipment. Nowadays, video transmission is common and simple, as long as there is professional equipment, people can complete it. Especially today's wireless video transmission has many advantages: relatively low overall cost, short installation period, convenient maintenance, and stable performance. In addition, it can be used as long as it is plugged in, the networking is quite flexible, and there is no need to layout the network and add equipment, which is very easy to use.

To Create High-quality Video and Audio Work, the Following Three Things Are Essential!(2022年12月02日)

HOLLYLAND — 2022-12-02T17:45:12+0900

In today's streaming media era, short videos, live broadcasts, etc. have gradually become the mainstream. While the requirements for pixels are becoming more and more stringent, users' requirements for sound quality are also becoming more and more stringent, which is why there are more and more People have begun to pay attention to audio, and the importance of picture quality is self-evident for an excellent video work. But again, clear sound quality is also essential. If there is no clear and shocking sound, no matter how gorgeous the picture effect is, it cannot attract more people to watch.

Below HOLLYLAND will tell you what tips you have when shooting video works and how to bring more good sound to video works through this content.

1. Please connect an external wireless microphone to your recording device

When conditions permit, please do not directly use the microphones that come with recording devices such as cameras, mobile phones, tablets, camcorders, etc. to participate in sound pickup. Judging from the actual feedback effect, the built-in microphones generally lack professionalism, and the picked-up sound will be full of various noises.

After all, devices such as cameras and mobile phones are supposed to shoot, not pick up sound, so the built-in microphone preamps and conversion circuits are not of high quality.

The automatic gain or manual gain function of this type of microphone will make the ambient sound more prominent, and the sound quality you can imagine.

In addition to the prominent noise, use the camera or the microphone that comes with the phone to record, and the microphone is close to the camera rather than the sound source. Try moving the camera lens, and you'll find that the sound you pick up is getting worse and worse.

In summary, to get broadcast-quality clear sound, you need to connect a professional wireless microphone to your recording equipment.

2. Choose the appropriate pickup equipment: wireless microphone

(1) Shotgun Microphone

For cameras, if you want to reduce the impact of ambient sound as much as possible, then the gun microphone is the best choice.

Shotgun microphones basically adopt a directional pickup design, mainly in cardioid and supercardioid directions. They have excellent sound pickup capabilities. They mainly pick up the sound source directly in front of the microphone, while the pickup of sound sources in other directions will gradually weaken. Most of them need to be used in combination with a DSLR and a camera, but in places with loud ambient noise or when the recording distance is far, the sound quality clarity will be reduced.

(2) Wireless Microphone

Wireless microphones are the first choice for most video bloggers at present. As the representative "character" of freeing hands and easy pickup, wireless microphones have many advantages such as easy portability, simple operation, and high cost performance. They are suitable for Vlog, live broadcast, street interviews, etc. A variety of pickup needs. The HOLLYLAND wireless microphone LARK 150 series uses high-quality omnidirectional microphones, which can flexibly receive 360° all-round sound, record the sound more accurately, and easily achieve broadcast-level sound effects, allowing you to experience the studio anytime, anywhere. level of recording quality.

(3) Desktop USB Microphone

The positioning of desktop USB microphones is mainly for indoor recording, and is often used in indoor live broadcast, recording studio recording and other scenarios.

3. Plan the accessories you need to bring in advance

This is mainly for bloggers who shoot outdoors. When going out to shoot, try to bring accessories such as wireless microphone system components, windproof and shockproof brackets, and windproof wool covers in case of emergency. In special scenarios, audio adapter cables, batteries, cold shoe adapters, metal back clips, etc. may also be required. The accessories mentioned above all require bloggers to plan in advance which ones need to be used and which ones may be used before going out to shoot, and make full preparations in advance to improve the recording efficiency and recording effect.

Today, more and more people choose to use their smartphones or other devices to participate and record every moment of their lives. Therefore, in order to ensure the video quality, we need a high-quality wireless microphone to help users enhance the sound quality of the video, which is also one of the important factors affecting the video quality.

A wireless walkie-talkie is an intelligent terminal for cluster communication. In the case of not using all the Internet, you can use it to make voice calls to each other, and there is no mobile phone bill, and it is suitable for places that are relatively stationary and often need to keep in touch. Indoor outdoor intercom system are commonly used in various fields and are also common special tools for vehicle system software.

Ⅰ. The application of wireless intercom

Indoor environments requiring frequent long-distance communication:

In restaurants, hotels, banks, and other places, people need to move around indoors frequently and keep in touch to ensure high-quality services. To this end, wireless intercoms can be used to connect venues such as halls, front desks, and back kitchens to maintain instant intercom, without waiting and responding quickly.

Indoors with poor signal or outdoors with no signals:

The walkie-talkie communication does not require a network, which is superior to the mobile phone.

When you're near a hotel elevator or hiking in the mountains, you may experience weak signals and can't make calls. Using a wireless intercom can eliminate this worry, and its penetrating power is vital, which is very suitable for outdoor travel.

Large-scale work areas such as warehouses and factories have relatively high requirements for walkie-talkies, and there ars some requirements for dustproof and waterproof levels.

Ⅱ. The advantages of wireless intercom

1. Freedom of Communication

The property company uses a wireless comm system, and the staff will know the needs more quickly throughout the work process. Moreover, the wireless intercom does not involve the network, which can avoid sudden network instability and make the intercom system smoother. If employees cannot be connected with on time, a work procedure may have problems, and wireless walkie-talkies can avoid it.

2. Economical and practical

Because the wireless intercom is not affected by the network, this new type of device can make communication quick. In this way, during the entire communication process, the operating cost and call costs of each person will reduce, and it will save the company more costs. In addition, the wireless intercom equipment also has a variety of functions, which are irreplaceable by other communication tools in the dispatching and commanding of the entire work.

3. Improve work efficiency

The use of wireless comm system can effectively improve the work efficiency of each employee. Especially for the hotel service industry, if there is any problem, you can use the wireless intercom device to call the maintenance staff, so as not to waste more time. The application of wireless comm system not only improve the work efficiency of the staff but also make customers satisfied for the overall service of the hotel. Work efficiency is a topic that every enterprise will pay attention to, so the widespread use of professional and stylish wireless intercom equipment will improve the low work efficiency in the past.

What Are the Types of Microphone Recording Equipment?(2022年12月02日)

HOLLYLAND — 2022-12-02T17:43:56+0900

When choosing a microphone for a recording studio, the question often arises: what is the best vocal microphone? How do you define "best"? To what extent is this definition correct? When choosing a microphone for an instrument or a singer, always try to find the one that best fits and captures its dynamic performance. But let's be clear: no one microphone will fit all singers and all songs. Understanding this is important for choosing the right microphone. Next, we will introduce several types of wireless microphone system one after another.
1. Dynamic wireless microphone system
A moving coil wireless microphone is actually a small speaker that generates electrical signals by sensing the vibration of air pressure. Dynamic microphones are very durable and can withstand high sound pressures, but they are less sensitive. While dynamic mics are generally not as sensitive to high frequencies, they are very effective when picking up drum kits, percussion, and guitar/bass amps up close. When used on vocals, dynamic mics can add warmth and dryness to the sound.
2. Condenser wireless mic system
The structure of the condenser microphone is more complicated, and it liberates the diaphragm that was originally tightly covered on the coil in the dynamic microphone. The advantage is that it is more sensitive to high-frequency sounds, and can increase the sense of presence that dynamic microphones lack. Condenser wireless microphone systems are the mainstay of studios of all types, and can handle the miking of most instruments.
Capacitor microphones can be divided into two types: large diaphragm and small diaphragm. The small diaphragm is less sensitive to low-frequency sounds, and is suitable for situations where you want to filter out low-frequency noise, such as acoustic guitars. The quilt can also add a bit of punch to the snare drum, and it's also great for picking up cymbals and percussion instruments. Larger diaphragms pick up more low frequency, and are suitable for situations where full-range sound is required. For vocals, pick up close range; when picking up instruments, generally 1 to 4 feet from the source to avoid overloading, unless the microphone has an output power switch function. The condenser microphone needs to be connected to an external power supply, which is generally provided by the preamplifier. Capacitor microphones are very sensitive to the quality of the power supply, and are not suitable for USB-supplied interfaces.
3. Tube wireless microphone system
The bile microphone is actually a step of adding a layer of electron tube amplification on the basis of the capacitor microphone. All mics require an external power source supplied by the manufacturer to be connected to an outlet, and are uniquely designed to ensure that there is only one correct way to access power. Gallbladder is very sensitive to the environment and can even make a lot of noise. It is usually necessary to turn on the power supply an hour before use to allow the tube to reach a stable state. Gallic mics are known for their warm, low-end potential and gritty high-end, making them ideal for vocal recordings. They are less expressive at high sound pressures, and are usually picked up at a distance for loud instruments. Due to factors such as power supply, wires, and design, the price of bile microphones is much higher than that of capacitor microphones.
4. Ribbon wireless microphone system
Ribbon wireless microphone systems are some of the most sensitive and unique in sound in the studio. A good ribbon mic can give you unimaginable detail, and that detail comes with the hassle of adding ambient noise. It is best to use it with a preamplifier specially designed for ribbon microphones. Modern ribbon mics are a bit more durable than older ones, and won't be scrapped immediately if they accidentally get plugged in. Never blow on the ribbon microphone. Traditional ribbon mics pick up sound at a distance, but modern mics can withstand higher sound pressures, which are great for picking up guitar amps.

Voice Secrecy Technology of Wireless Intercom(2022年10月26日)

HOLLYLAND — 2022-10-19T15:18:26+0900

https://www.hollyland-tech.com/intercom.html

Most of the intercoms now have private functions such as CTCSS and DTCSS. Generally speaking, when these private functions are set on the intercom, it is impossible to hear the content of the call without knowing the private line code used, but this is not true voice privacy. Because its security function is not very well, it is only useful for unintentional eavesdroppers but useless for intentional eavesdroppers. For users who need to have confidentiality requirements, they cannot rely on the "private" line for confidentiality.

1. The voice privacy of the wireless intercom system is to disguise the call information

Unauthorized people cannot understand the content of the call, and the disguised speech is called literal words. The process of disguising voice information is called voice encryption, and the encrypted voice information is called secret words. The set of rules and procedures used by the encryptor is called encryption algorithm, and the algorithm is usually carried out under the control of a set of keys. The recipient uses the secret key, which is used to encrypt the opposite algorithm, to restore the encrypted words to the literal words that they can understand. This process is called decryption or deciphering, and the process of deciphering the plain words from the secret words by the eavesdropper is called deciphering.

The voice encryption of the intercom is to process the voice information of the call, destroy its characteristics and reduce its intelligibility. After using the security function, the voice quality will be affected to different degrees, so pay attention to this problem when choosing the security level. Decryption is performed on most secure devices, and voice quality is affected by channel distortion, interference, and background noise. The cost factor should also be considered when choosing a security device. The higher the security function, the higher the cost of the security device. Therefore, various factors such as voice quality, security level, and cost of security equipment should be comprehensively considered when selecting security equipment.

2. The voice security technology of intercom is mainly divided into analog and digital voice security technology

Frequency domain scrambling is the earliest analog voice secrecy technology used in voice, and it is still widely used today. There are three commonly used techniques for frequency-domain scrambling: scramblers, band-shift scrambles, and band-splitting. Mainly use modulators and filters to achieve frequency shifting, frequency measurement and division.

Frequency scramble is the voice security technology that most of the imported wireless intercom systems are used at present. Frequency scramble is to exchange the high frequency and low frequency of the signal, that is, move the high frequency part of the signal to the low frequency band, and move the low frequency part to the high frequency band. The scrambled signal has the same frequency range as the original signal. The frequency components of the original voice signal are scrambled to reduce the intelligibility and play the role of voice secrecy. The same frequency scrambler is used to restore the signal at the receiving end. This frequency scrambler is the simplest speech scrambler, which is essentially an encoder. Commonly used scramblers do not have keys, so their secrecy is limited.

In addition, there is a frequency band-shift scramble, which is based on a frequency scrambler to introduce a key, and both parties to the call can use the agreed key for confidential communication. In this way, the band-shift scrambler becomes a real voice secrecy machine.

There is also a frequency band division, also known as frequency band scrambling, which is also the most commonly used technology in analog voice security machines.

The security of the digital voice security technology of the wireless intercom system is very good. Moreover, this system overcomes the difficulty of keeping density and voice quality in the analog voice security technology, so most of the digital voice security technology is used in important occasions.

Digital security systems include voice codecs, decoders, digital modulators, demodulators, and channel coders and decoders. The working principle is that the analog voice signal is digitally encoded into a digital signal through a voice encoder, and then converted into a digital encrypted voice signal through an encryptor, corrected by a channel encoder, and then transformed into a digital signal suitable for the sending end through a digital modulator. The analog signal transmitted by the channel. At the receiving end, the demodulator is restored to a digital signal, and then the voice signal is restored by a channel decoder, a decryptor, and a digital-to-analog converter.

The encrypted signal output by the digital voice security technology has pseudo-random characteristics, so it is only a piece of noise for eavesdroppers, which cannot be understood.

Classification of Wireless Intercom Based on Usage(2022年10月25日)

HOLLYLAND — 2022-10-19T15:17:41+0900

https://www.hollyland-tech.com/

1. Handheld wireless intercom

It is a small size, light weight and low power wireless intercom. It is suitable for hand-held or bagged, easy for individuals to carry around, and can communicate on the go. In the series of wireless intercom products, the number and variety of handheld radio "intercom" is the largest, accounting for more than 80%.

2. Vehicle-mounted wireless intercom

This is a wireless intercom installed on vehicles, ships, airplanes and other vehicles, powered directly by the power supply on the vehicle, and uses the antenna on the vehicle. The main applications are transportation, production scheduling, security command, and its size is relatively large. In the wireless communication network, the communication distance through the relay station is longer, which is tens of kilometers. With the rapid development of transportation, especially the increase of private cars, the number of vehicles purchased by individuals will increase day by day.

3. Forwarding wireless intercom

The forwarding wireless intercom product is to forward the received signal of a certain frequency band directly through its own transmitter on other frequencies. The two groups of signals with different frequencies do not affect each other, that is, two groups of users are allowed to communicate on different frequencies. It has the characteristics of sending and receiving and working at the same time without interfering with each other. Its distinguishing feature is that it can effectively expand the communication range and capability of handsets, vehicle-mounted machines and fixed stations in the communication system to provide a larger coverage radius for the system.

4. Amateur wireless intercom

This wireless intercom is specially designed and produced for the use of radio amateurs. This type of wireless intercom can also be called "playing machine". For this amateur personal radio service, various countries have opened up dedicated frequency bands for use by amateur radio sports enthusiasts. Most of the users of professional wireless intercoms are used in the professional business of group teams. Therefore, professional wireless intercoms are characterized by simple and practical functions. In the design, there are a variety of communication interfaces for users to do secondary development. Most of the frequency range settings are programmed through the computer, and the user cannot change the frequency. The panel only displays the number of channels, and does not directly display the frequency point. In long-term work, its stability and reliability are high, and the operating temperature range is wide.

5. Analog intercoms and digital wireless intercoms

In terms of design technology, wireless intercoms can be divided into analog intercoms (also known as traditional intercoms) designed with analog communication technology, and digital intercoms designed with digital technology. The analog wireless intercom modulates the stored signal to the intercom's transmission frequency, while the digital wireless intercom digitizes the voice signal and transmits it in a digitally encoded form, that means all modulations on the intercom's transmission frequency are digital. Only a intercom that directly uses a digital signal processor is a digital intercom in the true sense, while a intercom that uses digital control signals is not a digital intercom.

Digital wireless intercoms have many advantages, the first is that they can make better use of spectrum resources. Similar to cellular digital technology, digital intercoms can load more users on a designated channel and improve spectrum utilization, which is a solution to frequency congestion and has long-term significance. The second is to improve the voice quality. Because digital communication technology has in-system error correction, compared with analog intercoms, it has better voice audio quality in a wider range of signal environments, and it will receive less audio noise and clearer sound. The last point is to improve voice and data integration, changing the weakness of control signals that decrease with communication distance. Compared with similar integrated analog voice and data systems, digital intercoms can provide better data processing and interface functions, so that more data applications can be integrated into the same two-way wireless communication base station structure, making voice and data service integration easier. Perfect and more convenient. These three characteristics make digital intercoms an inevitable trend in the future development of intercom technology.

The Highlight of Recording Microphone: It is at the Cutting-edge of Recording Equipment(2022年10月23日)

HOLLYLAND — 2022-10-19T15:17:10+0900

https://www.hollyland-tech.com/

When it comes to the number one weapon in the hands of a recording engineer, it is the recording microphone. When recording, the quality of the microphone determines the overall quality of your recording. The sound recorded by a poor microphone cannot be improved no matter how you repair it later. Therefore, being proficient in microphones has become a necessary skill for recording engineers. Recording should be at least 70% important in the entire music production process. In the recording, the microphone should also have a proportion of more than 70%. In many cases, what is done in the post is just to make up for the lack of microphones in pre-recording or improper use. If we can use the lav mic well in the recording, we will be able to make it easier later on. A recording engineer should know as much about a recording microphone as a soldier knows about his own gun.

1. The directivity of the recording microphone

All microphones have a place to receive sound signals, here we call it the head, and the general position is behind the diaphragm. The capsule has three structures, one is a single-sided pressure-receiving type, and only one end is open so that only one side of the diaphragm can receive the sound pressure. Fully open, that is, both sides of the diaphragm can accept sounds from various angles. The last one, the specific principle will be described in detail later.

There is only one side of the diaphragm that can receive sound pressure, and the sound waves on the back will travel to the front, so they can also be sensed. In this way, sound from any direction can be picked up, so we call this directivity omnidirectional, or use a circle pattern instead. The diaphragm can receive various sounds on both sides, and the sound waves from both sides are respectively wound to the front and back sides, thereby generating the same pressure. The last case is that the backside sound waves are allowed to pass through the diaphragm, thus canceling out the sound waves going around the front side. Therefore, in this case, the rear sound cannot be picked up. This is a cardioid pointing microphone, and a heart pattern is generally used instead.

The head not only determines the direction but also determines the characteristics of the timbre. The single-sided pressure-accepting capsule can pick up natural and clear sounds, with excellent depth and realism, and low-frequency control is also very good. The pressure angle-accepting capsule will have a proximity effect. If used properly, it will have a low frequency, which can control the frequency response very naturally, but if it is not used properly, the effect will be very bad.

2. Recording microphones, headphones, and speakers

When you see this title, you will feel confused. Are these three related? The microphone is recording, and the headphones and speakers are playing back sound, which seems to be the opposite and completely irrelevant. But if we analyze their principles in detail, we will find similarities. Headphones and speakers both convert digital signals into vibrations of the diaphragm and make sounds, while microphones convert the vibrations of the diaphragm into digital signals. The difference between the two is only that the signal flow is reversed, which means that there will be some duplication of the characteristics of the two. The analysis of the relationship between the three is mainly to compare with headphones or speakers in the future, so as to have a deeper understanding of their characteristics.

Do You Know What Are the Transmission Methods of Wireless Audio Video?(2022年10月21日)

HOLLYLAND — 2022-10-19T15:15:45+0900

https://www.hollyland-tech.com/

1. Wireless audio video: point-to-point transmission

The simplest transmission of Wireless Audio Video is point-to-point transmission, also known as unicast, which is divided into two ways: one-way and two-way. This transmission method can be used for the transmission of video files, and it can also be used for the transmission of audio. Video on demand is a one-way video transmission, usually a video file serves a user alone. Bidirectional is the transmission between two network terminals, such as Internet telephony. Two-way transmission may consume more network bandwidth than one-way transmission, resulting in less resources available in the network and lower network usage.

2. Wireless audio video: single-point-to-unlimited multi-point transmission

This is a one-to-one broadcast method. For example, a server that sends wireless audio video usually sends audio and video to all nodes connected to it indiscriminately. The advantage of this method is that there is no need to control the routing of audio and video transmission, and each receiver can receive it. The disadvantage is that the non-personalized service is easy to cause flooding of traffic.

3. Wireless audio video: single-point to pre-selected multi-point transmission

This method belongs to multicast. It divides users into many groups according to their needs, and only transmits wireless audio video to users in a certain group who need the audio and video service. The multicast mode effectively saves network resources, but requires complex group member registration operations and a complete video multicast routing, establishment and maintenance mechanism.

4. Wireless audio video: multipoint-to-multipoint transmission

Multipoint-to-multipoint transmission is a form of conference, and its most direct application is a network conference. Network conference refers to the mutual transmission of audio, video and text data between two or more people or groups in different places through transmission lines and multimedia equipment to achieve instant and interactive communication. Each party in this communication network can send own video, and can also receive video transmitted from any party in this network.

Wireless audio video transmitter is a device that integrates communication, computer technology and multimedia technology. working application system. On the other hand, with the support of multimedia technology, the network conference system can help users to process various information in the work, such as sharing data, sharing applications, etc., thus constructing a work space shared by many people.

Development Prospect of Wireless Intercom System Communications(2022年10月20日)

HOLLYLAND — 2022-10-19T15:15:14+0900

https://www.hollyland-tech.com/

In recent years, the needs of wireless intercom system users for private network communications are not only "hearing", but also "seeing" and realizing "efficient command". The old voice communications products can no longer meet their needs. Users need comprehensive communications solutions covering voice, data, video, and more, and they also require professional communications systems to be seamlessly integrated with their internal management systems. The visual command and dispatch system for public security integrates various technologies such as voice, GPS, and GIS to adapt to ever-changing user needs, demonstrating a comprehensive feature.

1. Process of Digitization, Clustering, and Multimode of Wireless Intercom System Communications Technologies
The technology of wireless comms accelerates the integrated transmission capability of information, images, and data of digital walkie-talkies, and customized application software integrates communications of the action team with the work system, greatly improving work efficiency. This kind of mobile communications solution customized for different mobile work teams with the aim of improving efficiency, will become a new trend in both administrative and business fields.

2. Frequency of the Wireless Intercom System—Valuable Resource
With the rapid development of mobile communications, the contradiction between the limited spectrum resources and the rapid increase of wireless users has become increasingly prominent, and serious frequency shortage has occurred. The way out to overcome frequency crowding lies in adopting various technologies with rational utilization of frequencies. Compared with the analog FM walkie-talkie, digital walkie-talkie wireless comms can improve the efficiency of spectrum utilization, and at the same time, a variety of corresponding technology systems have emerged.

Meanwhile, some countries and regions are also actively formulating laws and regulations to guide wireless users to purchase and use systems and equipment that can improve the spectrum utilization rate from the policy level. For countries with extremely tight spectrum resources, the corresponding wireless regulatory agencies have also proposed specific handover timetables. Only by improving the utilization rate of spectrum resources and greatly improving the system capacity, can the development needs of future wireless mobile communications be better met.

3. Development of Wireless Intercom Systems
The development of users' commercial needs has promoted the integration of digital broadband and narrowband technologies. The current narrowband digital communications system can no longer meet the user's business requirements, and needs to rely on the broadband communications system in terms of voice scheduling, short data transmission, image transmission, and database access. However, in the field of professional wireless comms, the broadband system itself also has some shortcomings. For example, the broadband system needs to use small cell coverage to solve the problem of frequency reuse. Compared with the large-area system, the system cost is greatly increased, and the system reliability is reduced. In the case of emergencies, it is impossible to form an emergency communications network with a large coverage in the short term. Therefore, the existing narrowband trunking communications system and the broadband access system are combined to form a multimedia trunking fusion network integrating voice, data, image, and video, which can better meet the needs of industrial users and will become the main direction for the development of the next-generation digital trunking system technology.

2. Ambient humidity: 30% to 55%.

3. Dustproof requirement: The construction and daily maintenance of the equipment room should cover dustproof operations.

4. Waterproof requirement: During the construction of the equipment room, waterproof operations should be performed to prevent rain leakage and water inflow.

5. Environmental monitoring: It is recommended that monitoring measures be taken for temperature, ground humidity, smoke, access control, power supply, and other aspects during the construction of the equipment room.

6. Illumination: The illumination of the equipment room is required to exceed 300 lux.

7. Ventilation: Appropriate ventilation conditions should be considered during the construction of the equipment room.

8. Keep the diameter of the wire hole for the RF cable to enter the equipment room to be equal to or longer than 1 meter, and lay the RF cable on the equipment room frame.

9. Provide Internet access and cable TV access for the wireless talkback system base station.

Ⅱ. Ground Protection for the Equipment Room of the Wireless Intercom System

The ground wire of the equipment room is an important factor to ensure the stable operation of the wireless intercom system. Whether the ground wire connection method is reasonable will affect the stable and reliable operation of the wireless intercom system. It also affects protection of personnel and equipment against any incident. As such, the grounding system needs to meet the following requirements:

1. AC grounding wire refers to the neutral wire in the AC power supply, with grounding resistance of less than 5Ω.
