Wireless outdoor contacts


New Member
Does any manufacturer carry a wireless door contact that is compatable with the Concord 4 and is made for the outdoors? Particularly for cold winters? I live in MN and I' m thinking it would be handy to have a contact on the tool shed.
Is this a metal shed?

If so you'll probably need to mount an antenna on the outside, otherise you'll have supervision issues.

Also I have had better luck with a dual tech motion. It'll get you if you open the door, same if you enter any other method.
