Points in Prison Communications

Ensuring the smooth, real-time, unified command and dispatch of prison communication is an important part of prison supervision and security. The prison is not allowed to have the operator’s network signal, to prevent prisoners from communicating with the outside world privately to form unsafe risks. Within the scope of the monitoring area, a group of communication networks managed by themselves should be built to ensure that there is no blind spot in the monitoring area signal and full coverage of the signal.
