Anyone found a source for 12 volt IR detectors?

Looking for some advice on the most appropriate sensors for a moored
cruiser. I have switches on the door, the hatch and some windows, I have
two infra red motion detectors and a pressure mat.

Are the IR detectors any good on a boat that sways a lot in the wind etc?
Any other options?

Thanks in advance
