Greetings Folks,

We are getting a little stomped with our HikVision cameras, we have a few different models with your Audio cable - IN G OUT G.
We introduced an amplifier so we could drive a Horn Speaker but we are getting lots of noise & audio is coming out very soft and not being able to control it:

We got ourselves some screened audio cables but to no effect. What are we doing wrong?
Do we need to Ground somewhere else? I'll be honest the wiring for this particular step bothers me a lot.

Any help regarding this would be greatly appreciated.

Thank you.
