I just bought a new home and it had it professionally pre-wired for a security system. There are cables for sensors on all entry doors. There are some cables for motion detectors as well on the main floor. There is also a cable for the control panel near the main entrance. All the cables go to the basement and are not connected to anything at the moment.
I checked one of the cables and it looks like there are 4 (four) wires (red, black, yellow, and blue) inside.
Is this something I can make one of my DIY projects? If so, any recommendations on wired security systems compatible with this setup?
