Thank you @ Steve I will go look at some of these videos. Yes sir by “ security camera “ those are the ones I am referring to. As for the DTV receivers , ( two in front) “ are wired to an audio system and the input does not seem to make a difference. I am pretty tech literate when it comes to these things and you are right ! It’s very complicated business. Presumably, the prior owner used them ( the cameras) with no issues and is not very tech savvy to explain to me how to make them work.
I sure hate to embarrass myself by calling Newell Tech ?‍♀️
