LaserMonitoring COFDM Digital Wireless Video/Audio Receiver "GRX-2000A"

"Portabletype Receiver" is one of non-line-of-sight mobile video transmission equipment with a receiver screen. It is 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 could display video in real-time, save the video to hard drive storage and has many other central monitoring, remote management and data acquisition functions. It is waterproof, anti-seismic and easy to carry and powerful.

1. Features
   Multi-band down-conversion technology: 150 ~ 850MHz;
  Multi-bandwidth COFDM demodulator technology: 8/3.5/2.5/1.25MHz (optional);
  Multi-mode video decompression: MPGE4 compatible MPEG2;
  High receiver sensitivity, up to-111dBm (10-6 BER@1.25MHz channel width);
  Provides a wide range of external interface: the main channel interface,
   including AV video interface, Ethernet standard interface (10/100BASE-T adaptive),
   Des channel interface RS232 data interface, GPS data interfaces and two-way voice interface,
   in which two-way Voice Command for voice can be linked.
