I’ve always just tied my garage doors into my home security system using senors similar to those posted above. It works, but it’s admittedly clumsy. The wireless outfits are scary simply because they are battery powered. The wired units seem more industrial and I have had decent luck with them, but I’ve always wondered if there is a better way… or perhaps a more secure backup.
