COFDM Diversity 2 RF Antenna wireless video receiver
VCAN2131 COFDM Wireless Downlink Receiver
–160MHz~860MHz HD video COFDM wireless downlink Receiver with HDMI/AV/USB output
The VCAN2131 COFDM Diversity Receiver is a compact digital diversity receiver with integrated H.264/H.265 decoding in a compact and lightweight housing, suitable for use in fluid and high-mobility applications. The unit accepts signals from two antennas to significantly enhance the demodulated performance and increase the operating range. VCAN2131 can find and lock automatically to the incoming transmission quickly according to the pre-set frequency and bandwidth. This receiver features a range of comprehensive signal outputs, including HD at 720p and 1080p, down-converted HD CVBS monitor video, and two analog audio channels are supported.
VCAN2131 also includes DVR record functionality with a Micro SD card or a USB disk using REC switch controls. The VCAN2131 also enables video streaming over USB for remote Android device decoders like smartphones or Android tablets. This allows multiple remote viewers to monitor the same video simultaneously.
When paired with the our COFDM wireless Downlink camera transmitter, the SR300 offers a comprehensive, rapidly deployable video and audio solution that enables advanced situational awareness. It can play an essential role in delivering real-time live video from both ground and airborne mobile platforms.

Keys & LEDs:
The SR300 has 3 LEDs:
PWR LED: power indicator, red constant light when device is normally powered;
Link LED: wireless link indicator, green blinks when video stream is received;
REC LED: record indicator, green constant light when video recording
REC key: switch button for video recording, short press to change its status. The receiver will automatically check the storage device(micro SD card or USB disk, priority SD card) after power on and start to record video when the storage device is inserted. Just press the button to stop or record again.
OSD key: turn on/off the status of the OSD displaying, long press it to switch(more than 1s). The status will be kept after reboot. When the OSD status is on without any OSD data input from the data uart, the device will display information on the video screen as:
