Long Range 1.2GHz Video Transmitter and Receiver
This compact long range 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/PAL), TV, recorder and so forth. This high performance transmitter outperforms other transmitters in the market with these:
Use compact AV transmitter module with high output power (3W, 5W, 10W and 20W available)
Use high reliability/linearity/AIGaAs/GaAs FET amplifier module
Adopt digital phase-lock-loop circuit
Also available in 2.4GHz format
Transmitter (picture on the right below): Input jacks of video and audio for AV device such as video camera, TV....
Receiver (picture on the left below): Output jacks of video and audio to a display/recording device such as TV, recorder, computer....
Transmission range: Transmission range up to 1,500 feet (450 meters) in open space with high gain omni-directional antennas. Longer distance can be achieved if high gain directional antennas are installed on both sides under a line of sight environment. (NOTE: High gain directional antennas are mandatory if long transmission distance is anticipated)
Maximum transmission distance in an unobstructed environment using high gain directional antennas on both sides **
3W Model (35dBm) 7 miles (11 km)
5W Model (37dBm) 12 miles (19 km)
10W Model (40dBm) 40 miles (64 km)
20W Model (43dBm) 50 miles (80 km)
**These figures are for reference only.
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 to the opposite building.
Send video wirelessly between two mountains.
Send video from an outlying island back to the seashore.
Easy installation. Setup can be completed within minutes.

Transmitter's connecting wires

If the transmission path is a line of sight environment, the transmission/reception will be significantly improved by using Yagi directional antennas, panel antennas or other directional antennas.
It is strongly recommended to use high gain directional antennas (9dBi gain or above) for transmitter 5W, 10W and 20W models. Using antenna of lower gain would damage the transmitter.
These transmitters are not suitable for body-worn since the heat generated will dissipate through the aluminum housing.
