This might not be the place for this but I feel like someone here should know.
I moved into a new house recently and there’s a whole security system, infrared scanners, alarms on all the doors and windows, glass break detectors everywhere. When we open a door or window there’s a little chirp so something is working, but I’m curious if anyone knows if I can rewire this somehow or get a new panel so that I can actually set an alarm and stuff.
That looks like an old Ademco system. There will be a main panel somewhere, probably in a closet in a metal box that may or may not be locked. Typically near an outlet with a wall wart power supply.
Get the model numbers from the main panel and the keypad and you should be able to find manuals that will do into detail about all the possible features. These old units required a wired land line for reporting to work, so you might have to get creative for that.
