A dog door sounds simple until you realize a standard flap also welcomes raccoons, drafts, and the occasional neighborhood cat. High tech dog doors solve that with ultrasonic collars, motorized panels, and app control, so only your pet gets in and out. The trade-off is real: these systems cost more and need power, collars, and occasional maintenance. This shortlist covers full electronic doors, patio models, backup batteries, and the collars that make them work, so you can match the setup to your home and your dog’s size.

More Details On Our Top Picks
The PX-1 is where most people should start with this brand. Its motorized panel slides vertically instead of swinging on a hinge, and an MS-4 ultrasonic collar worn by your dog tells it when to open. The directional sensing is the detail worth understanding: the panel responds to a pet walking straight toward the door, not one lounging beside it or strolling past.
In daily use, that means fewer surprise openings when your dog naps near the doorway. The 4-way access switch lets you set In Only, Out Only, Full Access, or Closed and Locked from the panel itself. The airtight seal and automatic deadbolt keep weather and unwanted visitors out between trips.
Strong Points
- Directional sensing means the door ignores pets merely wandering nearby, cutting false triggers dramatically.
- The vertical sliding panel seals airtight, so winter drafts stay outside where they belong.
- An automatic deadbolt engages after each cycle, adding a layer of security passive flaps can’t match.
- Four access modes give you training flexibility without touching your phone.
Things To Consider
- The MS-4 collar system is older than the MS-5 used by newer Power Pet models, so confirm compatibility before ordering spare collars.
- Installation requires cutting a hole in your door, which isn’t reversible if you rent.
Who It Suits Best
Owners of medium dogs up to 30 pounds who want proven automatic access without paying for WiFi features they won’t use.
A Better Fit Elsewhere
Large-dog owners over 30 pounds should step up to the Power Pet PX2-WIFI, which handles dogs up to 100 pounds and adds app scheduling.
This is the modernized take on the PX-1 above, built around the current MS-5 collar platform. The clever engineering choice here is gravity: the panel closes under its own light weight rather than being driven down by the motor, which removes a whole category of pinch risk. A patented anti-pinch system reverses the panel upward anyway if it meets an obstacle during closing.
The translucent panel is shatter-resistant and can’t be lifted or forced from the outside, which matters more than most shoppers expect. Like its sibling, it offers Enter Only, Exit Only, Enter and Exit, or Locked modes. Note that performance coverage applies specifically when paired with genuine MS-5 transmitters, so aftermarket collars are off the table.
What We Like
- Gravity-assisted closing plus anti-pinch reversal makes this one of the safer automated panels for nervous or small-jointed dogs.
- The intruder-resistant translucent panel can’t be pried open or lifted from outside.
- Same 8¼ x 10 inch opening as the PX-1, sized for dogs up to 30 pounds.
Worth Noting
- You must budget for genuine MS-5 collars; third-party transmitters void the performance terms.
- Collar batteries need periodic replacement, typically every couple of months depending on usage.
Made For
Cautious owners of medium dogs who prioritize anti-pinch safety and tamper resistance over smart-home features.
Where A Sibling Pick Shines
Anyone wanting remote monitoring should choose the PX2-WIFI instead, since this model has no app connectivity at all.
A door is useless without a working collar, and this single MS-5 unit with two batteries covers exactly that gap. The collar emits a coded 40kHz ultrasonic signal, which simply means a frequency above human and canine hearing, carrying your dog’s direction of travel to the door’s circuitry. That directional data is what prevents the panel from opening every time your pet ambles past.
It’s rated waterproof to one meter, so rain, snow, and the occasional swim won’t kill it. Owners commonly report the signal holds strong even through thick fur, though battery life varies with how often the door cycles.
Bright Spots
- Genuine OEM status keeps your Power Pet door’s performance terms intact, unlike generic transmitters.
- Waterproof to one meter depth, so lake days and downpours are non-events.
- Ships with two batteries so you have a spare ready before the first one dies.
Small Caveats
- Single-collar packaging means multi-dog homes pay more per unit than the two-pack later in this list.
Right Fit For
Single-dog owners replacing a lost or dead MS-5 collar who want warranty-compliant hardware without buying extras.
Swap It Out When
Households with two or more dogs get better per-unit value from the Genuine MS-5 Collar 2-Pack with six batteries.
Electronic doors have one weakness their flap ancestors never did: no power, no access. This rechargeable B12V-1.3 snaps into any Power Pet model’s battery compartment and keeps the panel cycling through outages, good for roughly 1000 open-close cycles per charge. That’s weeks of normal use for a typical two-walks-a-day household.
Recharging happens automatically whenever the door runs on its AC adapter, so maintenance is essentially zero once installed. An optional CRG-12V charger kit, sold separately, lets the door run entirely off-grid without wall power at all. For rural properties or areas with unreliable grids, this small purchase removes the biggest objection to going electronic.
Plus Points
- Roughly 1000 cycles per charge means your dog keeps yard access through extended blackouts.
- Self-recharges through the door’s own circuitry, so there’s nothing to remember or plug in separately.
- Fits all Power Pet electronic door models, making it a universal upgrade across the lineup.
Points To Note
- Off-grid operation requires the separate CRG-12V charger kit, an extra purchase some owners overlook.
- Rechargeable cells degrade over years of charge cycles and will eventually need replacing.
Who Should Grab It
Any Power Pet owner in an area with frequent outages, or anyone installing a door far from a convenient outlet.
Another Choice May Suit
If your concern is collar coverage rather than door power, the Genuine MS-5 Collar & 2 Batteries addresses that side of the system instead.
The PX2-WIFI is what happens when the classic Power Pet formula gets a smartphone brain. Sized for large dogs between 30 and 100 pounds, it pairs with genuine MS-5 collars and adds app-based control from anywhere: lock the panel remotely, set schedules around the clock, and receive real-time notifications each time your pet enters or exits. Low-battery and fault alerts arrive on your phone too, which heads off problems before your dog is stuck outside.
The motorized panel still needs no pushing, and a safety retract system lifts it clear of any obstruction during closing. A steel deadbolt locks automatically after every cycle. Compared with the PX1-Medium reviewed earlier, you’re trading a higher price for monitoring and scheduling that busy households genuinely use.
Highlights
- Live entry and exit notifications let you verify your dog made it inside while you’re at work.
- 24/7 scheduling automates curfews, locking the door overnight without manual switching.
- Steel deadbolt secures against strays and would-be intruders between openings.
- Handles dogs from 30 to 100 pounds, covering most large breeds.
Honest Caveats
- WiFi setup adds a configuration step, and owners report occasional reconnection needed after router changes.
- Still requires genuine MS-5 collars, an ongoing accessory cost worth factoring in.
Quick Facts
Who Will Love This
Tech-comfortable owners of large dogs who want proof-of-entry alerts and scheduled access from their phone.
Not Your Match When
Renters who can’t modify a door should look at the Power Pet Sliding Glass Patio model, which needs no permanent installation.
Not everyone needs electronics, and the Armor Flex is High Tech Pet’s answer for giant breeds and brutal climates. Instead of a motorized panel, it uses interlocking flexible flap segments with magnetic alignment, a design that seals tightly against wind and rain while letting a 90-pound dog push through effortlessly. The industrial-grade aluminum frame carries a powder-coated finish that resists chipping through years of hard use.
A rigid security panel slides in when you want the opening fully blocked. Available in regular height for doors from 75 to 80¼ inches and tall height up to 96 inches, it fits standard and oversized entries alike. The honest read: you lose automation but gain simplicity with nothing to charge, pair, or troubleshoot.
Reasons To Buy
- Magnetic interlocking flaps block drafts and driving rain far better than single-flap designs.
- Powder-coated aluminum frame shrugs off rust, dents, and years of enthusiastic exits.
- Flexible segments reduce pinching risk for pets squeezing through quickly.
- Included locking panel secures the opening completely when you’re away.
Softer Spots
- No selective entry: any motivated animal that pushes the flap gets through, unlike the PX2-WIFI’s collar-gated access.
- Flap segments may need periodic cleaning to keep the magnetic seal seating properly.
Whose Shelf It Belongs On
Owners of extra-large breeds in windy or storm-prone regions who value a mechanical, maintenance-light solution.
Consider Something Else When
Households worried about stray animals entering should pick the Power Pet PX2-WIFI, whose collar requirement blocks uninvited guests entirely.
Here’s the Power Pet system for people who can’t or won’t cut into a wall. This version mounts into a sliding glass patio track, fitting openings from 75 to 80¼ inches, and serves dogs from 30 to 100 pounds. You get the same MS-5 collar activation, steel deadbolt, and hermetically sealed panel as the wall-mounted units, just without a saw touching your house.
A dual-range feature sets separate trigger distances for entering versus exiting, handy for multi-pet homes or patios close to sidewalks. The panel opens instantly and runs whisper-quiet, which matters in quiet evening hours. Assembly in the USA and straightforward track installation make this the least invasive automatic option on the list.
Standout Traits
- Installs in a sliding glass track with no cutting, drilling, or permanent modification.
- Dual-range control lets you set different approach distances for entry and exit.
- Hermetically sealed panel keeps wind, rain, and drafts out even in extreme weather.
- Automatic steel deadbolt locks the panel shut after every cycle.
Trade Offs
- Occupies part of your sliding door track, slightly narrowing the human walkway when installed.
- Requires genuine MS-5 collars for operation, adding recurring battery costs.
The Right Fit
Renters, condo dwellers, and anyone whose best pet exit is a sliding glass door rather than a wall or wooden entry.
Reach For A Different Pick When
Owners wanting phone notifications should choose the PX2-WIFI door-mount version, since this patio unit lacks app connectivity.
Multi-dog homes need one collar per pet, and this two-pack with six coin-cell batteries is the economical route. Each MS-5 emits the coded directional ultrasound your Power Pet door requires, with low-current circuitry stretching battery life toward the longer end of the typical range. A test button on each collar lets you check battery condition instantly, and the LED draws nothing when idle.
These are submersible to three meters, a step beyond the single-collar kit’s one-meter rating, and built tough for rough-and-tumble dogs. The included batteries use high-density 2430 lithium cells rated at 320mAh, above the roughly 250mAh common in generic equivalents.
Upsides
- Two collars and six batteries cover a second dog plus years of spares in one order.
- Submersible to three meters, so swimming and heavy rain pose no threat.
- On-demand battery test button eliminates guesswork about when to swap cells.
Room For Improvement
- Overkill for single-pet homes, where the single MS-5 kit costs less upfront.
Who Should Grab It
Two-dog households equipping a Power Pet door, or single-dog owners who want a ready backup collar on hand.
Where Another Pick Suits Better
Solo-dog owners needing just one transmitter are better served by the Genuine MS-5 Collar & 2 Batteries kit reviewed earlier.
What Matters Most Before Choosing High Tech Dog Doors
Match The Opening To Your Dog And Door
Size drives everything. A medium opening around 8¼ by 10 inches suits dogs up to 30 pounds, while large models handle 30 to 100 pounds. Measure your dog’s shoulder height and chest width before ordering, then confirm the door material: wood and metal doors accept cut-in mounts easily, glass requires a patio insert, and walls need tunnel kits.
Understand The Collar Ecosystem
Power Pet doors only activate with genuine MS-4 or MS-5 ultrasonic collars, and the manufacturer’s performance terms apply exclusively to authentic transmitters. Budget for one collar per pet plus replacement batteries every few months. Skipping this line item is the most common regret among first-time electronic-door owners.
Plan For Power
Motorized panels need AC power, so check outlet proximity to your chosen installation spot. The rechargeable backup battery in this list covers outages, and the optional charger kit enables fully cordless placement. Flap-style doors like the Armor Flex sidestep power concerns entirely at the cost of selective entry.
Think About Installation Reality
Door-mount units require cutting a hole, which is permanent. Patio inserts slide into existing tracks and remove cleanly, making them the default choice for renters. Weigh your lease, your DIY comfort, and whether you might move within a few years.
Key Considerations Across These Picks
Traps First Timers Fall Into
The biggest mistake is buying a door without checking collar compatibility, since Power Pet models reject non-OEM transmitters outright. Second is ignoring dog size: an undersized opening forces awkward crouching that discourages use. Measure twice, order once.
Why Top Tier Costs More
WiFi models command a premium for app control, live notifications, and scheduling hardware. That spend pays off for working owners who want confirmation their dog got back inside, or anyone managing curfews remotely. For simple yard access, mid-tier units deliver nearly identical core function.
Frequently Asked Questions
Do high tech dog doors work for cats too?
Yes, provided the cat wears the compatible ultrasonic collar and fits through the opening comfortably. Many owners use them for both species in multi-pet homes.
How long do MS-5 collar batteries last?
Typical life runs two to four months depending on how often the door cycles. The test button on genuine collars lets you check status anytime.
Can other animals open an electronic pet door?
No, the panel stays locked unless it detects the specific coded signal from a paired collar. Strays and wildlife cannot trigger it.
Are these doors difficult to install?
Door-mount versions require cutting an opening, a moderate DIY job with basic tools. Patio models slide into an existing track in minutes with no cutting.
What happens during a power outage?
The door stops operating on AC power alone, which is why the backup battery exists. With one installed, the door continues cycling for roughly 1000 operations per charge.
Bottom Line
For most medium-dog owners, the Power Pet PX-1 remains the sensible starting point, while large-dog households get real value from the PX2-WIFI’s alerts and scheduling. Renters should head straight for the sliding patio version, and multi-pet homes need the two-collar pack from day one. Whichever route you take, add a backup battery and measure your dog before ordering, and the whole system will feel effortless within a week.
