How The Electronic Pet Door Works

The electronic dog door is powered either by batteries, electrical plugs or by both. This type of door uses high technology in oder to make life easier for the dog and its owner. These doors are specially designed and will only open for the dog that is wearing a special collar piece. This will keep other animals and potential crooks from entering the house. Of course, the technology of these automatic doors makes them more expensive, but they are worth it.
Traditional pet doors give the dog freedom to come and go, but they do not keep undesired elements out of the house such as cold weather and leaves like an electronic pet door can. 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 They Function
Although they can vary a bit from manufacturer to manufacturer, these doors usually work in the same way. The dog has to wear a collar, which in turn emits an infrared or a magnetic frequency; this frequency can be picked up by the door's sensors and it causes the door to open.
It doesn't matter if your dog approaches the door from inside the house or outside of it; the door will open itself 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.
A electronic pet door has sensors that can even detect the size of the being that approaches it, telling human from animal, and thus it won't open for burglars, even if they somehow get hold of the collar.
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.
