◆Simple connection
The wireless system is plug-and-play designed, without any software connection and configuration
Remark:
1. The transmission distance may be different, and depend on surroundings, radio wave conditions, buildings,
etc., the 300 meters transmission distance may be not guaranteed.
2. The wireless transmission might be interrupt if there’re many other devices of 5GHz wireless bandwidth
operated in the in the same location.
3. Signal reception may be affected by the position, height and angle of devices. If reception video is not stable,
please physically adjust placement for the optimized signal.
4. Set the antennas straight up and set receiver higher will enhance the transmission efficiency.
5. The product offers the AES 128-bit encryption to protect the wireless transmission. Anyway, please be ware
of the intentional capture from third person.
