Electronic Pet Doors
Pet doors can be a bad idea from a home security standpoint (if your dog can slip in the backdoor, so can a thief--even doors for small dogs are problematic, since someone can stick an arm through and unlock the lock), but electronic pet doors may provide a more secure alternative. With these pet doors, your dog or cat wears a special collar embedded with a radio or infrared transmitter. The receiver in the pet door opening mechanism only tells the door to open for your pets. If the door is designed correctly, burglars should have a hard time gaining entrance through the entrance.
