Electronic Pet Doors | Automatic Dog Doors and Cat Doors
In evaluating an electronic doggie door the first question is, "Does the door really open and close by itself or does it just unlock, requiring the pet to push it open?" Most so called "electronic pet doors" on the market are not opened by a motor and require the pet to push open the panel. That is something that a lot of pets don't like to do. Motorized electronic doggy doors are in a class by themselves, giving you huge advantages over electronic dog doors that merely unlock. Not only are motorized dog doors convenient for you and your pet, they are better sealed and far more secure. This is because the linear track in which the panel moves up and down provides a continuous, air tight seal and also provides a mechanically stronger holding mechanism that resists being kicked in by an intruder. Electronic dog doors that just unlock and swing open have to seal the sides of the swinging panel. These seals are not air tight and allow air to pass through just like flap doors, making them susceptible to drafts, less energy efficient and less secure against intruders, just like flap doors. Electronic dog door models like the Petsafe Smart Door and the Petsafe Passport are not motorized and are simply not in the same class of a Power Pet door (although, they like to advertise as if they were). There are also various magnetic and electro-magnetic dog and cat doors that operate a simple solenoid that unlocks the door when is senses a magnet on the pet's collar. Such products are made by Ideal Pet Products (a very good dog door manufacturer), Dog Mate and others. These types of products really do not provide much more in the way of security or insulation than a conventional flap door and don't really warrant much consideration here.
