This wireless microwave transmitter enables you to send video between locations where hardwiring is difficult or impracticable. The transmitter operates on microwave radio system - no internet connection required, no bandwidth to worry about. It is therefore particularly useful in those remote locations where there is no internet/network coverage or out of WiFi range.
Compatible with most video cameras with RCA or BNC AV outputs (NTSC and PAL auto detect). See a typical setup here.
This high performance time-proven transmitter comes with these outstanding features:
Use compact AV transmitter module with high output power (3W, 5W, 10W and 20W available)
Use high reliability and sensitivity Comtech tuner module
Use high reliability/linearity/AIGaAs/GaAs FET amplifier module
Adopt phase locked loop circuit to eliminate frequency drift
Also available in 2.4GHz and 900MHz frequency bands.

With BNC/RCA AV input jacks for connecting to device such as video camera, camcorder, CCTV hard-wired camera ....
Receiver

With RCA AV output jacks for connecting to display/recording device such as monitor, TV, DVR, computer....
Transmission range: Range may vary substantially depending on the actual operating environment. Much longer range can be achieved in
aerial applications. Range is about 1,500 feet (450 meters) in
open space with high gain omni-directional antennas of 12dBi or higher. Longer distance can be achieved if high gain directional antennas are installed in a line of
sight environment - see table below. Wireless signal can pass through some walls, trees and other obstacles, but in this case, the transmission distance will be much shorter
due to signal attenuation through obstacles.
| Maximum transmission distance in an unobstructed environment between two static points using 12dBi 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) |
**For reference only.
Viewing live video feed over the internet or mobile phone.
If you have a DVR or video encoder and other equipment connecting to the internet, you may connect the wireless receiver to one of the video inputs of your DVR/video
encoder so that you can view the camera
footage live in your local network or in a remote location over the internet on your cell phone. See a typical setup here.
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
power consumption details.
Easy installation.
Setup can be completed within minutes.

Antenna notes
2) For 5W, 10W and 20W transmitters, it is recommended to use antenna of at least 9dBi gain or above.
3) Yagi antenna is a directional antenna. It is recommended to use only if the distance between the transmitter and the receiver is a line of sight environment.
4) If it is necessary to use antenna extension cable, the cable should be kept as short as possible because, the signal attenuates directly proportional to the length of the cable, i.e. the longer the cable, the weaker the signal from the antenna. To minimize the signal attenuation, you may extend the distance between the transmitter/camera or the receiver/monitor by using high grade 75 ohm coaxial video cable such as RG6 cable. See an illustration here.
Packing contents
2) 4-channel 1.2GHz AV receiver with a 6dBi omni-directional antenna
3) One 12VDC power split cable (except 20W model).
