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.

Quality construction

Very easy to install. It is a solid product. Expensive but worth every cent. You get what you pay for.

The first dog door was great quality but was just a bit tight for my dog; I contacted Chewy and they promptly agreed to exchange it for the next size

Looks like it might survive my little chewer, Woody. We'll see!

If this one works, will definitely get one for the other dog door as well. Fingers crossed.

It has positives and negatives

Pro: This thing seems very well built. Cons: The unit sold by chewy claims to be a door and wall version, but doesn't come with the tunnel. You have to buy that

Pro: This thing seems very well built. Cons: The unit sold by chewy claims to be a door and wall version, but doesn't come with the tunnel. You have to buy that separately from the manufacturer. Additionally if you have a thick wall like a stucco with insulation, the tunnel isn't long enough. I've tried emailing and calling the manufacturer for advice but they haven't gotten back to me. Summary: If you have a normal wall or a door this might be a good quality dog door for you.
