Product Precautions

This product belongs to wireless video transmission equipment. Please pay attention to the precautions carefully

to avoid the damage of the terminal equipment or the injury of ourselves caused by improper usage or operation.

Installation Notice

1. Be sure the antenna is installed before the transmitter is power on. Otherwise it will cause damage to the circuit.

2. Make sure the transmitter, receiver, power supply voltage is within a predetermined voltage range, otherwise it will cause

damage to the circuit.

3. Try to make the transmitter antenna is vertical down and no obstructions to avoid the communication distance is shortened

because of obstructing.

4. The transmitter antenna should be kept away from large pieces of metal parts.

5. Be sure to use the specified models of antennas to ensure that the parameters match the band impedance.

6. Keep a appropriate distance between the electronic devices When install, thereby reducing electromagnetic interference

between devices to a minimum.

Usage Notice

1. Make sure that all the cables are high fasten and interfaces are correct.

2. This product requires about 15 seconds to start up, and thereafter it can be used for image transmission.

3. Make sure there is no interference frequency from the high-power wireless transmission equipment in the surrounding

environment. Otherwise it may cause the receiver can not receive the image properly.

4. When the received signal of the ground is not so good, you can try to improve by changing the inclination direction of the

receiver antenna.

5. As for the matched HDMI cables, displays and other components, please try to use good electromagnetic shielding

performance products.

Product Introduction

Our wireless HD image transmission products, using the H.264 video code, COFDM digital modulation technology to overcome the poor

signals and unstable communication effects and other technical problems in the condition of Simulation technique and conventional

modulation technique. It can be implemented the real-time high-definition video transmission in the case of high-speed motion

shooting.

Detailed technical advantages as follow:

support single transmit to single receive, single transmit to multiple receive application mode;

long distance transmission, it can be up to 20Km;

HDMI video input and output, resolution up to 1080P60;

high environmental adaptability, working temperature range -30

~ + 50
