In justice and law, House Arrest Solution (also called home confinement, home detention, or, in modern times, electronic monitoring) is a measure by which a person is confined by the authorities to their residence. Travel is usually restricted if allowed at all. Using a GPS tracker for house arrest is an alternative to being in prison while awaiting trial or after sentencing.

Monitored House Arrest Solution
While house arrest gps tracking devices can be applied to criminal cases when prison does not seem an appropriate measure, the term is often applied to the use of house confinement as a measure of repression by authoritarian governments against political dissidents. In these cases, the person under house arrest often does not have access to any means of communication with people outside of the home; if electronic communication is allowed, conversations may be monitored by the house gps tracker for inmates.

G737 Ankle Bracelet
The gps monitor house arrest can be enforced through the use of a gosafe gps G737 ankle bracelet. The house arrest bracelet waterproof G737 is locked around the offender's ankle (technically called an ankle monitor, also referred to as a tether). The G737 looks like an RF signal to a home beacon that is transmitting its ID which is whitelisted in the G737 ankle bracelet. The house arrest gps monitoring communicates with the backend server and sends the installed home beacon ID which confirms that the offender is staying at home. Once the offender goes too far from their home the G737 will send a disconnection event to the server or via SMS to the authorities and it can be recorded as a violation. This can be notified to the police as well depending on the case to case.
Vandal Resistant
The G737 ankle gps house arrest bracelet and the home beacon both are designed to be tamper-proof and if any attempt to temper the devices will also generate an immediate alarm and sent it to the back-end server as well as via SMS to relevant authorities.
