With the implementation of "Safe City", the application of vehicle-mounted surveillance high resolution thermal imaging camera is increasingly wide. So how to select the right vehicle-mounted surveillance camera? Let's share some points of purchasing the vehicle-mounted surveillance high resolution thermal imaging camera.

1. Broad range of vehicle-mounted surveillance high definition thermal imaging camera
Vehicle power supply is the car battery. Most people know that the automobile power supply is divided into 12V and 24V. Therefore, when choosing the power supply of high resolution thermal imaging camera, it is generally acceptable as long as the product meets the requirements of 12V and 24V power supply. But this is often not the case. The situation of automobile power supply is actually quite complex and changeable which means 12V or 24V is just a standard value. During the driving process, the power supply is a fluctuating value whose primary range is about 8V to 30V. Abnormal conditions such as ultra-low voltage/current or ultra-high voltage/current happens very often. Among the projects that have been implemented, there was a case that the power supply was only 6V when the vehicle started (of course, the vehicle was aging), but reached 60V high in an instant. In this case, most of the equipment cannot start normally (especially the 12V or 24V power supply), or even burn down the machine.

2. Anti-interference performance of vehicle-mounted surveillance high resolution thermal imaging camera

It should be noted that due to the environmental complexity encountered by the vehicle power, many interferences, such as electromagnetic interference, to the supply are unpredictable. The power supply is also a important problem in anti-interference.

Therefore, in selecting vehicle-mounted surveillance high resolution thermal imaging camera, the first thing should be paid attention to is the selection of equipment power supply. A sophisticated and tested vehicle-mounted DVR has at least the following features in terms of power supply: ultra broad voltage input, anti-interference, DC circuit output (which can br the supply power to both high resolution thermal imaging camera and the smaller monitor), over-current and over-voltage protection device equipped, safety design of long-time power on work, shutdown function (preferable) (which can continue to work for a while after the vehicle flameout to ensure the continuity of surveillance and the system safety). The power supply should have an independent safety device with different protection lines (such as independent hard disk protection circuit) set up to prevent the damage of the host equipment and hard disk caused by over-current, overload, incorrect connection of positive and negative pole as well as other problems.

The power supply of the vehicle is too complex. Companies that have done good jobs in the vehicle-mounted DVR in the industry all made things done by repeatedly modifying and enhancing the power supply for at least one to two years. After several painful after-sales experiences, the techonology gradually stabilized.

The above are the points of purchasing the vehicle-mounted surveillance high resolution thermal imaging camera. you are welcome to learn about it. As an important part of intelligent transportation, vehicle-mounted surveillance high resolution thermal imaging camera system will provide strong guarantee for vehicle scheduling management, driving safety and vehicle utilization improvement .
