Aiday Automatic Sliding Glass Dog Door with Collar Sensor (Large)

The door opens automatically as the dog approaches and locks after an 8-second interval. A single control button adjusts the sensing range to accommodate different spaces. The product includes two exclusive sensor collars for reliable detection and a patent-pending design on the sensor system. The frame adjusts to fit sliding doors from 76″ to 80-11/16″ in height, with a 10″ wide glass opening. This configuration suits medium-to-large dogs up to 100 lbs and is well-suited for households that want automated, pet-safe access during set hours.

This X-Large model from Aiday expands the same sensor-based access to extra-large dogs, up to 220 lbs. The door still uses two exclusive sensor collars to prevent intruders from triggering entry. It shares the 8-second auto-lock, adjustable sensing range, and custom scheduling. With a frame height range of 76″ to 80-11/16″ and a 13.4″ wide glass opening, it’s designed for oversized pets while maintaining smooth sliding door aesthetics. Manual override remains available for situations requiring non-sensor control.

This Tall variant by Aiday continues the sensor-driven access with the same collar system and scheduling controls. The adjustable height range stretches from 90-9/16″ to 95-1/4″, catering to tall doors and specific installation heights. The 10″ wide glass opening provides ample space for large dogs while maintaining secure, automated operation. Like the other Aiday models, it emphasizes pet-controlled access with a safety lock after entry and secure fit to minimize drafts around the frame.

The installation process involves drilling, reflecting a more permanent modification aimed at long-term durability and a patent-pending approach to the opening mechanism.

Buying Guide: Key Purchase Considerations
- Pet size and weight: Choose a height and opening width that accommodates your dog’s size and movement without friction or obstruction. Models with higher weight ratings are appropriate for large or XL dogs.
- Sensor vs. non-sensor: Sensor collars provide automated entry control and can reduce unwanted access, but may require ownership of compatible collars and battery maintenance. Non-sensor, manually controlled doors may be simpler and more cost-effective.
- Installation approach: No-cut or DIY-friendly options are ideal for renters, whereas fixed, drill-reliant installations often offer superior durability and security for long-term homes.
- Door swing direction: Some doors open inward, some outward, depending on left- or right-side installation. Measure your door orientation before purchase.
- Height adjustability: Sliding glass doors come in varied frame heights. Select a unit with an adjustable height that covers common door tracks from around 75″ to 81″ or higher for tall doors.
- Door opening size: A wider opening reduces friction for large breeds and enables easier passage. Ensure the opening width aligns with your dog’s shoulder width and gait.
- Durability and security: Look for tempered glass, aluminum frames, and hinge or locking mechanisms that withstand local weather and frequent use.
- Energy efficiency: A well-sealed frame minimizes drafts. Check for weatherstripping and tight tolerances around the door insert.
- Warranty and support: Consider brands with clear warranty terms and accessible customer support, especially for sensor systems and components like collars.
