PetSafe Electronic SmartDoor
Other than alleviating the fear of intruders, this digital doggie door has plenty of smart uses. If your pet is wearing the SmartKey on his collar and tries to go through the door, radio-frequency technology reads the collar’s unique signal and unlocks the flap. It automatically locks back into place when your pet’s SmartKey is out of range. This means, depending on what pet is given a SmartKey, you can let your dog go out while keeping the cat inside, give your cat access to the litter box while keeping the dog out, or any other number of scenarios unique to your home.
