About High Tech Pet Motorized Power Pet Doors

Automatic Pet Doors

Power Pet doors open and close on their own and feature a translucent door panel made of bullet-proof resin. When your pet approaches, the ultrasonic M5 collar activates the panel and quietly powers it upward. The panel then safely closes into sealed grooves for weatherproof, airtight closure.

Relax and Feel Secure

Relax instead of jumping up every time your cat or dog wants to come in or go out—the ultrasonic collar triggers the door automatically. The fully programmable automatic pet door lets you decide when your pet can come and go, and the deadbolt-locked door panel keeps out critters and intruders.

Designed for Door or Wall Installation

Engineered for performance, design, value and reliability in all weather conditions, Power Pet Doors install easily into either doors or walls. The motorized doors come in two different sizes to accommodate large dogs or smaller pets and feature a translucent sliding door panel made of high-strength acrylic resin. For wall installation, purchase the additional wall tunnel adapter, sold separately.

Sliding Glass Patio Door Inserts

Turn any sliding glass door into a fully automatic pet door with these easy to install, full-height inserts that include an integrated Power Pet Door. Made of high-quality aluminum framing with a durable powder-coated finish, these weatherproof doors feature dual-pane tempered glass to insulate in even the harshest conditions. A spring-loaded top section makes for quick installation and a locking deadbolt helps ensure security.

Collar-Activated Automatic Doors

MS-5 Ultrasonic Transmitter Collar

Each Power Pet door comes with one small, lightweight MS-5 Ultrasonic Transmitter collar that easily adjusts to fit your cat or dog—additional collars can be purchased separately for other pets, too. The collar’s directional sensing system opens the door only when your pet directly approaches.

Added Security and Weatherproofing

After your pet walks through the Power Pet Door, the translucent door panel slides vertically to safely close it with an airtight seal. A deadbolt automatically engages to secure the door and keep out wild animals, neighborhood pets and intruders.

Fast and Easy Installation

Everything is included for door installation or use the optional Wall Tunnel (sold separately) to install in exterior walls.

Dual-Pane Tempered Glass

Our Sliding Glass Patio Door inserts feature high quality aluminum framing and dual-pane, tempered, LOW-E Glass for extra energy efficiency.

Secure Locking Patio Insert

Your sliding glass door Power Pet insert comes with a heavy-duty latch to securely lock the door shut against your existing sliding glass door.

Battery or AC/DC Power

Your Power Pet Door comes complete with a rechargeable battery or you can use the supplied AC/DC plug-in adapter.

Very nice magnetic door flap

The step height is very high. Cats would no longer use it. Only one dog adapted. Reused old door in the end.

Biggest waste of money I have ever spent. Every time my dog goes in or out, the door slides down and almost closes, but then opens again. And it will do it 4 or 5 times before finally closing- half the time I have to help it close. Not very handy when it is 15 degrees outside, my heating bill is going to be through the roof! Took a video but you can only post still photos. I also tried to post a review on the high tech website and it would not let me, very interesting. Super aggravating but do not waste your money like I did!

The construction of the door frame is good quality but I was missing several of the screws used to put in the locking mechanism. The latch mechanism is light and easily damaged. The door is not as deep as my sliding door so I had to jury rig a fix so it was solidly set in place. The pet door itself is great. It uses magnets to close so there are no gaps. Once I added more weather stripping and fixed the door in place it met my needs. I did get a different locking mechanism and installed it to ensure my home was secure.

We've had this for about 8 months now. Pro - easy to install, flap is heavy, very convenient. Con - not very much room to walk out the door yourself when this is installed, lock is really cheap and broke quickly, no replacement flaps for this very expensive purchase. My huskies are hard on this and the flap is on its way out

I had a Petsafe door for 4 years and this one is exponentially better for keeping out weather. It stays shut in even the highest winds. Very weather tight. Holding up to 3 large dogs slamming through it constantly. Only downside so far was the installation method. I would recommend getting rid of the factory lock tab and just screwing it to the frame in the same manner Petsafe is installed. Otherwise it will not seal well.

It’s cold when temperature drops. Top sliding piece has no insulation. Door frame itself seems to be hollow. It does stay shut in high wind but the plastic in the dog door becomes brittle and breaks over time. I glued the bottom flap on one fix but when the door broke at the top and the entire dog flap was outside, the door is done. Expensive, cold and doesn’t last
