You have a large dog that needs freedom to roam the yard, but you also worry about stray animals sneaking in. The choice between a smart pet door and an automatic pet door comes down to how much control and connectivity you want. In this guide, we compare two top options from High Tech Pet: the WiFi-equipped Power Pet Smart Roll Up and the factory-refurbished Power Pet Automatic. Both use ultrasonic collar technology to keep your pet the only one passing through, but each serves a slightly different budget and lifestyle.

Buying Guide

Control and Access Modes

The smart pet door gives you four access modes (enter only, exit only, full access, locked) plus dual smart range control that adjusts activation distance for entry and exit separately. You can also set 24/7 weekly schedules through the optional WiFi app. The automatic pet door offers the same four modes but without remote scheduling or app control. If you want to manage your pet’s comings and goings from anywhere, the Power Pet Smart Roll Up Automatic Dog Door stands out. For simpler, set-and-forget operation, the automatic model still gives you full in/out control at the panel.

Security Features

Both doors lock automatically after each use, but the smart door adds an electronic locking system that resists forced entry and includes an extra security panel for when you leave home. The automatic door uses a steel dead bolt that engages instantly. A safe return feature on the smart door prevents accidental lockouts by always letting your pet come back inside. The automatic model’s anti-pinch safety system raises the door if it detects an obstruction. For pet owners in areas with many stray animals, the smart door’s advanced security may be worth the extra investment. For more on pet tech safety, visit our Pet Tech Guides home.

Installation and Power Options

Both doors mount in a standard door and include an AC adapter. The smart door requires a household outlet and can be paired with an optional rechargeable battery backup for outages. The automatic door (refurbished) also supports a backup battery but does not include WiFi connectivity. Installation is similar: you cut a hole in your door, mount the frame, and connect the motor unit. The smart door’s added electronics need a clear signal to your home router, so plan its location accordingly. Each unit is assembled in the USA, and the refurbished model comes with a full warranty just like a new one.

Value and Warranty

The automatic door is factory refurbished by High Tech Pet and carries the same warranty as a brand-new unit, making it a cost-effective choice for budget-conscious owners. The smart door is new and includes premium features like WiFi control, smart detect, and dual range. Both require the authentic MS-5 ultrasonic collar (included with the automatic, sold separately with the smart? Actually the smart door description says “designed for MS-5 collar” but does not explicitly say it includes one; the automatic says “comes with a brand new MS-5 Collar included”. So the automatic includes the collar, the smart may not. Check product details: for smart it says “AUTHENTIC MS-5 COLLAR TRANSMITTER” but not explicitly included? The automatic says “comes with a brand new MS-5 Collar included”. We should note that. But price cannot be mentioned. We can say the automatic offers great value for those who want a reliable door without extra connectivity. Refer to our comparison section for more insights.

Final Thoughts

Choosing between these two comes down to how much automation and control you really need. If you want remote scheduling, voice control with Alexa or Google Home, and the ability to manage your pet’s access from anywhere, the Power Pet Smart Roll Up Automatic Dog Door is the clear winner. If you prefer a straightforward, secure door that includes the ultrasonic collar at a lower investment, the Power Pet Automatic Pet Door, Large Door Mount delivered refurbished with a full warranty is a smart choice. Both keep your home safe while giving your dog the freedom they deserve.

Frequently Asked Questions

What is the difference between a smart pet door and an automatic pet door?

A smart pet door connects to WiFi and can be controlled remotely via an app, often integrating with voice assistants. An automatic pet door operates without internet, using a collar transmitter to unlock the door when your pet approaches. Both prevent unwanted animals from entering, but smart doors offer scheduling and monitoring features not found on basic automatic models.

Can I control my pet door remotely?

Yes, if you choose a smart pet door like the Power Pet Smart Roll Up. Through the optional WiFi app, you can open, close, lock, or manage access from anywhere, and set weekly schedules for both entry and exit. Standard automatic pet doors require manual interaction at the door panel unless you upgrade to a smart model. For more on connected pet tech, check our Pet Tech Guides.

Is a refurbished automatic pet door reliable?

Factory refurbished doors from High Tech Pet are reconditioned at their USA facility, certified “like new,” and backed by the same warranty as a new unit. They include a brand-new MS-5 ultrasonic collar and have been rigorously assessed for performance. For many pet owners, a certified refurbished model offers a dependable way to get premium features at a more accessible price point.

Which High Tech Pet door is better for large dogs?

Both the Power Pet Smart Roll Up and the Power Pet Automatic are available in large door-mount sizes that accommodate most large breeds. The smart door offers dual range control so you can set how close your dog must be to trigger entry or exit, which can be helpful for very energetic pups. The automatic door’s steel dead bolt and anti-pinch safety are also well suited for larger animals. Choose based on whether you want WiFi features or a simpler, collar-only system.
