I saw the movie "Over The Hedge". There was a dog that had a collar that would activate a doggie door that only a critter with the collar, and maybe a critter tagging along with it, could pass through, then it would lock again. I haven't seen such a device. Are there such things? And if so, do they work? Anyone that has used these, if you might chime in? Thanks.

It was a cat. But look at this:
Google, Automatic Doggy Door
Or "electronic dog door"

Hmm, intersting. It's infrared though; too bad they don't make one using a radio signal - more reliable less prone to dirt/fur messing it up.
Any further sources?

How about an ultrasonic activated Star Trek style?
