So I am about to install a couple of recessed door sensors. Should I install the magnet on the door or in the door jam? I am thinking it is better to install the magnet in the door itself and the sensor in the door jam. This way the sensor is not moving around and potentially getting banged around if the door is slammed shut?
Am I thinking about it backwards or does it not really matter, or am I thinking right?
And what about the overall location of the whole setup? Top of door, side of door where the doorknob is, or bottom of door?
