A electronic dog door can be powered by batteries or by plugging it to a regular home electrical outlet. This door uses state of the art technology in order to give your pet a greater degree of freedom. 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. With this system, no other animal will be able to get 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. Also, while both types of pet doors let your dog inside, only the electronic pet door will close after your dog is inside, which might save it from other dogs or cruel children.
How These Doors Work
The specific design may vary from model to model, but they all usually work on the same principle. 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.
The door will automatically open after the dog passes through and it will lock until the dog returns to pass through again. There are also styles that allow the owner to use a remote control device which allow the owner to control when the door is opened or closed.
It is interesting to know that a electronic pet door's sensors can tell the difference in size between a dog and a person, and thus won't open to burglars.
Price
Price will not only depend on the material and size of the automatic dog door, but also on the number of features it has, with prices ranging from $40 to up to $700.
Other features include battery back up and different locking options.
The electronic dog door gets its power from batteries or by connecting to a normal electrical outlet. It locks after the dog comes in, keeping animals and rain outside. While a bit more expensive, a electronic pet door will offer more benefits than a regular dog door.
