PetSafe® Electronic SmartDoor™

The PetSafe smart pet door you to control the access of your pets. When the smart door is set to automatic mode, only your pets wearing the smart key can pass through the smart door. As your pet enters the adjustable range of the smart door, the smart door detects the smart key and unlocks it automatically. The range is adjustable up to 3 feet. After your pet passes through the smart door, the door will lock automatically. Without the smart key, no other animals can pass through.
