Common faults and Solutions
The output image may be flickered by interference. The quality of the wire used may be
poor, and the shielding layer of the wire is not well prepared. When there is a strong radio
near the use environment, radio waves may interfere with the transmission of the signal,
resulting in unstable signal flicker. Please use the wire produced by regular manufacturers,
such as Belden, Canare.
