High Tech Power Pet Door review
Published 20 June 2026
A fully motorised door for dogs up to giant breeds, opening via an ultrasonic collar sensor. A solid panel slides up and seals shut, giving better security and weatherproofing than any flap and no gap for wildlife. Premium and power-dependent.
Best for: Large and giant dogs needing a secure motorised door

How it scores
We rate every product in this category on the same criteria, weighted by how much they matter in daily use. Each score is out of 10.
| Criterion | Weight | Score | Why |
|---|---|---|---|
| Recognition accuracy and reliability | 25% | 8.5 | Ultrasonic collar sensor opens reliably; directional sensing avoids false triggers |
| Security and stray exclusion | 20% | 9.5 | Solid sliding panel seals fully, no flap for wildlife to push, the most secure design here |
| Weatherproofing and seal | 15% | 9.0 | Solid panel gives excellent weatherproofing and insulation, no flap gap |
| Response speed | 10% | 7.0 | Motorised panel takes a moment to slide open, slower than a flap |
| Pet capacity and compatibility | 10% | 7.0 | Collar-sensor based rather than microchip; suits the registered collar wearers |
| App and access control | 10% | 5.0 | No full app; operated by the collar sensor and unit controls |
| Installation and fit | 5% | 6.5 | Larger install, sizes up to 16x23.5 inches for giant breeds; more involved fitting |
| Value | 5% | 6.5 | Expensive and mains-dependent, justified for large dogs needing security |
| Weighted total | 7.93 |
How we score: each rating combines the manufacturer specification with the weight of feedback from owners and independent reviewers. We do not copy other reviews. The score is our own synthesis, and we show the reasoning so you can judge it yourself.

Common questions
How is the Power Pet different from a flap?
It is fully motorised: a solid panel slides up when your pet's collar sensor approaches, then closes and seals. With no flap, there is no gap for wildlife to push through and far better weatherproofing, making it the most secure design here.
Is it good for big dogs?
Yes, it comes in sizes up to 16x23.5 inches, large enough for giant breeds, where most flaps top out at small dogs.
What is the downside?
It is expensive, needs mains power, and the motorised panel opens a little slower than a simple flap. Installation is also more involved given the size and wiring.
