COFDM Digital AV Transmitter Receiver - 200mW

This 2.4GHz digital AV transmitter enables you to send video and stereo audio from one location to another without expensive and messy wiring. It works with regular video cameras (NTSC or PAL). It is capable of extending the IR control of your remote controller - see a sample system setup here. The transmitter set works with or without using the IR control feature.

The transmitter works on its own transmission system and is therefore particularly useful in those locations where there is no internet coverage or out of WiFi range. No internet connection required. No bandwidth to worry about.

The transmitter sends high quality video and stereo audio wirelessly to the included receiver. Transmission effectively avoids common radio interferences caused by other wireless equipment such as blue-tooth, cordless phone, WiFi etc. operating in the vicinity. Random ID coding between the transmitter and the receiver secures the privacy of video transmission.

Transmitter. AV signal sent out from the transmitter can only be received by a receiver matching the random ID code. The pairing process between the transmitter and the receiver can only be done within a 3-meter range. A transmitter can only be paired with one receiver at a time. RCA input jacks of video and stereo audio on the front panel for AV input from devices such as video camera, DVD player ....

Receiver. By pressing the "pair" button on the receiver, it will automatically pair with the transmitter using a pseudorandom sequence for a channel with random ID code, which is only known to both the pairing transmitter/receiver. RCA output jacks of video and stereo audio on the front panel for connecting to a display device such as TV, monitor, DVR, computer....

Viewing live video feed over the internet or mobile phone. If you have a DVR and other equipment connecting to the internet, you may connect the wireless receiver to one of the video inputs of your DVR so that you can view the camera footage live in a remote location over the internet or on your cell phone. A sample setup can be found here.

Frequency Hopping Technology. Adopting Frequency Hopping Spread Spectrum (FHSS) and auto pairing with random ID to avoid unauthorized reception, interception or jamming. These technologies also substantially reduce interferences from other sources of radio disturbances to ensure a steady and quality video stream.

Extra feature Apart from sending AV signal, this system also enables you to control a IR source device connecting to the transmitter, from the receiver side using your existing remote controller. Application example: playback the video stored in your DVR located in your setting room, on your TV located in your bedroom.

Power. Both the transmitter and the receiver work on DC12V power. Two AC/DC power adapters have been included in the package for this purpose. In those areas where AC power is not available, you may connect the devices to external DC12V battery such as solar-powered system or Sealed Lead Acid rechargeable battery. See Specifications below for more details.

Easy installation. Set up can be completed within minutes.

Transmission Range
Range may vary substantially depending on the actual operating environment. Much longer range can be achieved in aerial applications. Up to 300 meters (1000 feet) open space with the included omni-directional antennas. Longer distance up to 5 km (3 miles) can be achieved if high gain directional antennas are installed in a line of sight environment. AV signal can travel through some obstructions such as wall, partition, tree and so forth but in this case, the transmission distance will be reduced depending on the type, materials and the number of the obstructions in the transmission range. Overall, signal transmission is much better than FM transmitter particularly in multipath environments such as urban area.
