I am replacing some old cameras that came with the home to more modern ones.

I took apart 1 of the cameras to find this: enter image description here

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 other end of the cable is a disaster. It must split somewhere and the video part goes into this:enter image description here

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
