LaserMonitoring OFDM Digital Wireless Video/Audio Receiver "GRX-1000"

"Racktype Receiver" is one of non-line-of-sight mobile video transmission equipment. It is 1U rack-mount receiver, and mainly used to receive and process video signals from transmitter in non-line-of-sight environment. It uses advanced COFDM all-digital modem technology, combining the latest in IT field of audio and video compression/decompression technology, network technology, GPS positioning technology. It also could be used for the central alarm monitoring, remote management and data collection. Its appearance is simplicity. It is powerful, stable, anti-seismic and easy to install.
