Automatic Dog Door Types – Features Separating the Electronic Dog Doors under Review

As stated earlier, different dog doors deploy varying technologies or working mechanisms. These differences are the only assurance of understanding the ideal electronic pet door for a non-regrettable purchase.

However, despite the tools having different working mechanisms, they all work ideally to offer your pet safe passage into and out of the house. Besides that, each model has its pros and cons, all of which are covered in the item review section. At the moment, let’s look at the principle that different auto dog doors deploy and find the one that fits your needs to perfection.

  • Chip-enabled dog doors

They are the best in terms of efficiency and security. Chips are embedded in your pet, and they are ideal door triggers. They also help prevent stray dogs from entering your house. Besides that, chips can be used to track lost pets and know when they are hurt.

  • Magnetic doors

These work under two different mechanisms. However, they all require an ideal dog collar to work. In the first principle, the magnet on your dog’s collar pulls the lever on the door as your dog approaches, thus releasing a mechanism to open it.

In the other mechanism, the door is triggered by the magnetic field from the collar and opens. All in all, the opening is smooth and quiet. Magnetic doors are advantageous since they don’t require any power source to work. You, therefore, have nothing to worry about when it comes to battery replacements or recharging.

  • Radio Frequency Identification doors

These are highly effective and equally expensive. They are almost similar to magnetic doors in their opening mechanism, although RFID doors detect another implanted device having a particular electromagnetic field. The tags in your pet must match with the door settings for it to open, making RFID doors perfect when it comes to preventing other pets from entering. 

  • Ultrasonic wave doors

These doors are triggered by high-frequency waves emanating from the fixed sensors. One advantage of ultrasonic wave doors is that pet owners can easily adjust the sensor’s sensitivity to prevent regular opening when the dog gets close to the door. Likewise, the waves can be directed so that when the door doesn’t open if the pet is heading to the door without the intention of going out.

  • Radiofrequency chip doors

The doors open upon detecting close-range radio frequency signals. However, there is no specific information embedded in the device, meaning any dog with a radiofrequency chip can easily gain entry to your house.

Electric Doggie Doors Buyer’s Guide – Considerations When Buying an Ideal Dog Door

Under this section, you will find some factors to consider when purchasing a smart dog door. These features are the only way you are assured of making a non-regrettable purchase. So, let’s get started and ensure you get a pet door worth the investment.

  • Size

You need to measure the size of your pet before buying an electric dog door. After recording the height and width, do not buy an exact fit. Ensure the door is over 2 inches tall and 2 inches wide than the recorded dog size.

This allowance enables your pet to use the entry point even after a few years of growth. Additionally, if you need a door for your puppy, ensure you consider the maximum size of adult breeds so that the item accommodates your pet for long.

  • The incorporated sensor

Microchip sensor doors are the best option as they are highly secure, and they easily differentiate between pets. The doors are even a better choice if your dog already has a microchip implant.

All in all, ultrasonic and RFID doors are also highly recommended as they are cheaper. Lastly, radiofrequency and magnetic doors have a major flaw in the way they don’t contain embedded dog data; therefore, the doors are accessible by all dogs with a similar detector.

  • Design

The items come in two designs; door and wall-installs. Door-installs are easy to put in place as compared to wall-installed pet doors. This is because, for thick walls, a tunnel is required, thus complicating the process. However, the location of a dog door is more of a personal choice, which can only be made by the pet owner.

  • Frame

Here, you need to choose between a plastic and aluminum frame. However, plastic frame doors are cheaper and a viable option for small puppies, whereas aluminum ones are ideal for large and stubborn breeds.

  • Energy efficiency

Regular opening of dog doors causes a change in your in-house thermal degrees. Therefore, you need to consider insulated doors or those with an extended tunnel so that it minimizes the amount of cold air entering as your dog leaves or accesses your house.

How to Use an Automated Pet Door

Automatic dog door openers have different working mechanisms; therefore, their process of use varies. All in all, most of these doors require you to install them on a wall, glass panel, or door and fit your dog with a microchip implant or collar that will trigger the door to open, once the pet is close enough. In some cases, the pet won’t have to push the door to open as some open when the dog approaches.

How to Install an Electric Door for Dogs

The device is advantageous as you can install it without professional help. Here is the easy and simple process to follow for ideal pet door installation.

  • Ensure your tools and door are within reach.
  • Use the provided cutting template to outline the pet door on the wall or door.
  • Use a cutting tool to make a hole following the drawn template. If you are installing on a door, unhinge it for a precise cut.
  • Check if the hole you’ve made fits your door perfectly.
  • Secure the door using the conveyed screws but do not overtighten. Additionally, use caulk to make an airtight seal.

Frequently Asked Questions Concerning Automatic Doggie Door Openers

Under this section, you will find some essential answers to electronic dog door questions that might be bothering you. They should enable you to understand the item better before purchasing it.

  • Do pet doors compromise your house safety?

Well, traditional pet doors will pose a huge threat to your home security as they aren’t ideally made to keep intruders and other animals out. However, the item under review requires specific triggers to open, thus making it hard for strange dogs and people to enter.

  • What are the power requirements of an electric door?

As seen in most items under review, these doors are battery powered, but most batteries last for 6 or 12 months, meaning that replacement is at most twice a year. Additionally, there are magnetic doors that do not require electricity or batteries to operate.

  • Where can I install my electric door?

Well, there are multiple options for electric door installation, and first, it depends on the type of door you’ve purchased. An automatic dog door for sliding glass door can be used on a glass panel and such specific product fit in given settings. Additionally, door installs will not work on walls without purchasing additional wall installation accessories for the kit.

Final Thoughts

As I wind up my electronic dog door reviews, we can all agree that electric doggie doors are convenient for pets and pet owners. Purchasing an ideal item will undoubtedly make you understand the real benefits of these uniquely made devices.
