I am replacing some old cameras that came with the home to more modern ones.
Now I am guessing the yellow is video, and black and red are power (hot and neutral?)
I am not sure what the wire beside the yellow one is doing. I should add these were most likely installed by Brinks a long long time ago.
Here is another camera I want to replace:
Here the wire coming in has 5 wires? 1 video and 4 power? Hmm not sure what to make of that.
The cameras I bought are Lorex ones that use power and bnc cables:
I am guessing I have to cut that cable open and splice it in? Does anyone know if the supplied cable has three wires? two in the power part, and 1 in the BNC part?
The power might go somewhere here:
But I'm not sure...
I also wanted to install a video doorbell where there used to be a working camera:
This camera has 3 lines into it: black red white. I am assuming two power and 1 video? Most likely DC power? From my understanding the nest and ring ones use AC power -- so this will probably not work?
Sorry for the long post, need some help! Thank you
