Analog camera's audio and video system integrationcan use shielded cable to prevent signal interference . Use independent transmission cable is a very necessary stepin analog monitoring system.Most of the signal interference is caused by the distance from the high voltage cable. It is recommended to use the multi audio encoder, the most critical is to ensure that the lowest line of analog signal wiring.

Monitoring system,external microphone, speaker deployment is too dense also would cause sound interference , echo occurs in the audio input and output sound cycle, in order to avoid this kind of echo, installation the microphone and loudspeaker in a reasonable position, and another method is through a special codec to eliminate echo, using digital filter to eliminate audio echoes.
