My home has an old security system which has long been disabled.
I'd like to be able to use the wiring for the sensors to possibly provide DC power to some wireless IP security cameras in various areas. For example, at the end of one hallway is a motion detector formerly used by the system which I'd like to rewire for camera power.
The control box for the security system has wiring from the mains incoming for power, and a bundle of wires for sensors branching throughout the house. Would I be able to, say, replace the control box with a standard power outlet, attach a UPS, then attach the AC adapters for the cameras to the UPS, and (taking the wire lengths into account) extend the power cables accordingly?
