Detailed introduction
Functional uses:
COFDM micro transmitter is the equipment of COFDM wireless image transmission standard list. At the scene of an emergency, staff members carry small cameras to connect to COFDM micro transmitter, and collect and transmit images and sounds of the accident scene to the command vehicle or temporary command headquarters in real time. The commander can analyze the situation on the spot, so as to organize dispatch and remote command.
