4 Send a closed wireless video transmission equipment: The system uses advanced mobile communications core technology COFDM (multi-carrier modulation technology), is a highly integrated mobile NLOS digital wireless video transmission equipment, can move at high speed and urban buildings real-time transmission of audio and video under stable occlusion. The device can also be placed in the hidden parts of the hidden person transmission. Mainly used in technical surveillance and forensic police and security inspection department. Products: ST6000TTSE COFDM (multi-carrier modulation technology), highly integrated mobile NLOS digital image transmission technology, high-speed mobile and urban building block case transmit real-time audio and video stabilization. The device is compact, light weight, ideal for portable, suitable for use in buildings barrier environment, barrier environment can transmit 100 ~ 500m, depending on environment and receiver barrier height may be erected in the open environment, transmission may up to 5km ~ 10km.
