Operation Instructions:

  1. Both transmitter and receiver are equipped with AUDIO and VIDEO socket, input signal level 1Vp_p, power input DC12V.
  2. 4pin cable connects camera and power input. The 4pin cable has two ends: one end connects transmitter, the other end has Red, Yellow, White and Black 4pins: Red pin for DC12V power, White pin for audio, Yellow pin for video, Black pin for GND.
  3. Press buttons on transmitter and receiver to change channels, there are LCD screens showing channel numbers.
  4. Make sure transmitter and receivers are in same digits channels.

Installation Tips:

  1. Screw on antenna first before power on device in case of short circuit.
  2. Test your device indoor first to see video quality and then apply to real application environments.
  3. After installation, user can adjust antenna angle and switch channels to achieve best A/V quality. In case of Non-Line-of-sight, user can extend antenna cable or A/V cable to avoid interference.
  4. To achieve further transmission range, user may purchase optional high gain antennas


Q1: On the manual, transmission range only refers to line-of-sight, what about range in non-line-of-sight areas? How many floors, walls your wireless signal can penetrate?

A1: Transmission range varies from different environments. A 3watts transmitter can cover 2KM range in open spaces, yet in downtown, it may only cover 300 meters because of concrete building, metal and wireless interferences. It is possible to pass 100 meters or tens of meters in an environment with many buildings. It is recommended to avoid these blocking and find the best signal position.

Q2: What is the video resolution of your transmission system?

A2: The transmission system will be same as camera resolution. If you receive unclear images, please check camera settings first.

Q3: Can I use one transmitter with multiple receivers or the other way round?

A3: We suggest one transmitter working with one receiver. However, you can use multiple transmitters to work with one receiver (need auto/manual switch receiver channels), or multiple receivers with one transmitter (same images usually applied to multimedia classroom or showroom).

Q4: How many sets of transmission systems can be used in one same location?

A5: Wireless systems may interfere with each other in same location. It is suggested to use multiple wireless systems in different frequencies, such as 1.2GHz, 2.4GHz, and 5.8GHz etc. You can also keep receivers at a distance.

Q5: why is the transmitter so hot?

A5: It’s because there’s a heat sink device connects to transmitter case. The transmitter can work under heat condition 7/24 with no concerns, don’t worry.
