A electronic pet door can be powered by batteries or by plugging it to a regular home electrical outlet. This type of door uses high technology in oder to make life easier for the dog and its owner. The door has detectors that can sense the presence of a special collar that your pet has to wear, and will open only when this collar approaches. This will prevent other dogs or animals and even potential burglars from going into your house. Of course, the technology of these automatic doors makes them more expensive, but they are worth it.

Unlike regular pet doors, automatic pet doors will let your dog come in and go out whenever it wants, but unlike regular pet doors, they will not only keep other animals out, but also water from rain and dust from the street. In addition, while a regular dog door will let your dog in too, only the automatic dog door will close and lock after your dog is inside, maybe saving it from attacks from other dogs or mean children.

How do they work?

There are various kinds of doors but they generally function in the same way. The door has some sensors which make the door open when they detect a magnetic (sometimes infrared) signal emitted by a collar that your dog has to wear at all times.

Whether the dog comes from inside or outside the house, the door will open for the pet and then it will lock itself again. There are some types which include a remote control that let the owner keep the door closed or opened regardless of where the collar is.

One of the unique features about an electronic dog door is that people cannot activate the door because the high-tech sensors can detect the difference between an animal and a person
