I’ve been looking into options for wired security cameras, and in doing so ran into some confusion with the cables already in the house.

The house has been pre-wired with all kinds of cables leading to a central location. All currently terminate in bare wires with no connectors.

I’ve identifeid a couple of Cat6 cables which lead to spots outside the house. No problem there.

Then there are 5 or 6 other cables which I’m not sure about. I can see “Datolex JSC .5 Security Cable” printed on them. Each cable has 4 wires inside (black, red, white and blue). Some are marked “lounge”, “hallway” etc, and a couple more have “alarm” or “siren” (I forget exactly).

Now doing my reasearch on different cameras, I cannot figure out how to use these cables. They aren’t ethernet or coaxial, which seem to be the main types of cables for modern cameras. The ones marked witih locations, I was able to trace to points high up where a camera would be. Maybe they are supposed to be used for something else?
