Outline
The Video portable transmitter and receiver with two-way audio adopt the advanced modulation technology COFDM and the channel codes. It combines with digital image compression MPEG2/MPEG4/H.264 multimedia network transmission technology. Besides, it adopts the MPEG-2 video & audio compressed mode, and 2M and 8M bandwidth. This transmission system has the function of non-sight transmission, diffraction and penetration, and it can realize the image transmission and the bi-directional audio communication. This transmission system has the function of non-sight transmission, diffraction and penetration, and it can realize the image transmission and the bi-directional audio communication. This device is wildly applied in fields such as Public security, armed police and so on.
Features:
Supports COFDM modulation mode
The resolutions are: 720*576 25 frames/s, 1920*1080i 25 frames/s, 1920*1080i 30 frames/s, 1280*720p 50 frames/s, and 1280*720p 60 frames/s
The transmitting distance can reach 1-3 kilometers.
Supports one video and two audio transmission
Supports MER ≥22dB
Supports close-distance and moving(non-vision distance) real-time AV signal transmission
It can cooperate with satellite image car as a repeater.
Users can quickly switch the power; and the device has wide voltage range, high efficiency and low power consumption.
The device adopts aluminum milled parts as that it has good shield performance, excellent heat dispersion and high reliability.
The device is so small and light that the operation is easy and simple
