Long Range 1.2GHz 2W AV Transmitter and Receiver

 

This compact wireless video transmitter enables you to send video and audio from one location to another without expensive and messy wiring. It works with all types of AV devices including video camera (NTSC or PAL), TV, DVD player, recorder and so forth. This mini high performance transmitter outperforms other transmitters in the market with these:

Use compact AV transmitter module with high output power (2,000mW)
Use high reliability/linearity/AIGaAs/GaAs FET amplifier module
Adopt digital phase-lock-loop circuit

Transmitter (picture on the right below): 1.2GHz 4 channels selectable by a sliding switch. Input jacks of video and audio for AV device such as video camera, DVD player, TV....

Receiver (picture on the left below): 1.2GHz 4 channels selectable by a sliding switch. Output jacks of video and audio to a display/recording device such as TV, recorder, computer....

Transmission range: Transmission range up to 2,000 feet (600 meters) in open space with high gain omni-directional antennas. AV signal can travel through some obstructions such as wall, partition, tree... Longer range up to 5 miles (8 KM) can be achieved if high gain directional antennas are installed on both sides under a line of sight environment.

Sample applications:

  • Send video wirelessly from a surveillance camera to TV, monitor, computer, recorder.
  • Send video wirelessly from the surveillance cam at the main gate back to the house.
  • Send video wirelessly from the surveillance cam at the cashier counter to the office.
  • Send video wirelessly to the opposite building or hill.
  • Send video stream from R/C helicopter or airplane to the ground.

Easy installation. Setup can be completed within minutes.
