The all new and improved, PX2-WIFI Automatic Pet Door represents the state of the art in electronic dog and cat doors. Like all genuine POWER PET Models, it is operated by your pet with a small pet collar transmitter. It opens completely under its own power, so your pet doesn’t have to push open a flap (something the many pets don’t like to do.) But, there is no need for a flap. This pet door uses a vertically sliding panel that is hermetically sealed in its track so that it is 100% air tight, even in Hurricane force winds! The panel is secured by an automatic locking, steel dead bolt that prevents the panel from being lifted by an intruder or stray animal. Our smart phone app is also new and improved for quick, easy connection and intuitive operation. It allows you to control and monitor the Power Pet door from anywhere with a WiFi connection. Open and Close the door, Control Exit and Entry permissions, Set an unlimited number of individual entry and exit timers to allow your pet to come in or go out on the schedule you choose. The app can control an unlimited number of doors and may be shared with family members or pet care givers. The door can also be operated via the convenient manual control panel. The PX2-WIFI door comes with our improved MS-5 automatic pet door collar which is now even more rugged, waterproof and comfortable on your pet. The MS-5 collar uses a unique, patented ultrasonic signal that is directional. This allows the Power Pet door to open when your pet is on a direct approach, not when it is just wandering by or sleeping next to the door. Operation is quiet and extremely quick allowing the panel to open in about 1 second. Perhaps best of all, the Power Pet WIFI door is manufactured by High Tech Pet Products, Inc., a US based company and leader in the manufacture of automatic pet doors for over 35 years. From High Tech Pet, you can expect the highest quality product backed by our highly trained US based customer service team who will provide friendly, knowledgeable, HUMAN support when you need it. No other pet door even comes close to a genuine Power Pet door from High Tech Pet.
