Wireless door/window alarm sensor.

[Bradford Abbott]

Has anybody installed a wireless door/window alarm sensors to their boat. Was wanting to put 1 on the door. In case somebody opens the door at the dock the alarm will go off Don’t want a monitoring system.
if anybody has installed 1 what system are you using .

I've thought about installing a pressure sensor mat on the deck. Not sure how big/practical it would be.
