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. Such products are made by Ideal Pet Products (a very good dog door manufacturer), Dog Mate and others. 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. 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). 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 doors that just unlock and swing open have to seal the sides of the swinging panel. 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. Not only are motorized dog doors convenient for you and your pet, they are better sealed and far more secure.
Motorized electronic doggy doors are in a class by themselves, giving you huge advantages over electronic dog doors that merely unlock. That is something that a lot of pets don't like to do. What About Motorized Doggie 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. By that definition Power Pet is the World's only truly Fully Automatic electronic dog door. What is "Fully Automatic"? We define "Fully Automatic" as being a pet door that not only uses a motor to automatically open an access panel but, one that also has 4 way access control, auto safety retract, directional sensing and automatic dead-bolt locking. In fact, our PX-2 large model is the single largest selling pet door (electronic or not) on Earth! That's why genuine Power Pet doors outsell all other electronic pet door brands combined.
They are fundamentally superior to all other competing electronic pet doors. Power Pet doors were created by some of the nation's best engineers. The fact is, no other electronic dog door or cat door on the planet even comes close. S ince the creation of our original Power Pet ®door in 1992, many so called electronic dog doors have come and gone, several claiming to have some of the features of the genuine POWER PET product. Electronic Dog Doors are NOT All Created Equal
