Radios, cameras, vehicles and the control room. How to choose the set in the request.
Satellite radio
PoC needs data. UHF and VHF need range on site. Iridium talks over satellite when both fail.
Patrol
A guard on patrol, a radio in the vehicle and a post at reception. Without all three, the conversation breaks halfway.
Fleet
The tracker says where the vehicle is. The MDVR shows what is happening on the road and in the cab. They are two jobs, not the same unit under another name.
Vehicles
The vehicle sees the road and the cab. The control room sees the patrol. Streamax and Howen close in the quote with GPS tracking.
