What To Do With Old Alarm Panel Wiring - Replaced With Nest

I'm contemplating replacing my home alarm with the Nest Alarm system. For those that have gone down this route, what did you guys do with the wiring coming out of the wall for the old alarm panels that were previously installed with the home? I'm assuming my current panel some electrical wires coming out of the wall to supply power to the panel. I'm weary about just capping the wires and then patching the walls.

Is there a possibility of just putting a closed plate on it somehow? Curious what others have done.

I have an old alarm system in my house that used to have the window break sensors in every room. As I am slowly chipping away at painting each room, I take off the glass sensor and stuff the wiring in the wall. Then I patch it up and paint it over. The main unit has been disconnected and battery removed. It's low voltage, you won't damage anything if there is no power going to the main unit.

Use low voltage covert to micro USB and power a cheap tablet like Amazon fire hd 7. Use smart tiles as your interface to arm and disarm your alarm and view cameras, see weather etc.

I have some home entertainment system wiring (speaker, controls) that were covered up with blank wall plates by a previous owner:

I guess it depends on where the panels where and if the plates will cover, etc. Usually those plates are used with an electrical box so you could try to see if it can be screwed directly onto the drywall. If you wanted to use a box then I've used something like these for low voltage wiring but that'll probably require a larger opening:

As others have pointed out it's low voltage wiring. The DSC alarm systems I've familiar with uses 12 VDC for power. Might be an idea label the wiring before you remove the old stuff in case you ever wanted to reuse the wiring for something in the future (smart home, M2M/iOT sensors...)?
