Have searched and checked the first 15 pages but cant seem to find the asnwer. Every amp (4) I have purchased and tested, once I plug camera audio output into an amp, there is alot of static noise, and when I trigger some of the cameras inbuilt recordings, there is also alot of noise, dahua jsut say it is shielding and that is all,
Issue is, all cables are shielded, common power supply for both camera and amp, have tried a ground loop isolator.
So the question, what amps have been actualyl been used successfully with Dahua camera's?
