When it comes to electronic pet doors, there is a huge variety in the market to choose from. These pet doors are made a little differently from the flap doors; they are more like grooved, sliding doors that reduce draft, in turn reducing the loss of heating and air conditioning. Being power driven, these doors are electronically operated by the sensor attached to the pets collar, allowing only your pet to come in and go out and not the strays.

The opening and the distance need to be adjusted until the pet becomes familiar with the door. Made up of golden brown, transparent lexan, it is framed in strong, black aluminium that is anodized. The interior plate is made up of textured acrylic, which can be painted black to match the exterior trim plate. These doors operate on 115 volts of current. The power cord is supplied, along with the kit, which contains two sensor keys (these sensors are of different sizes for small and big pets) and an attachable clip for the pets collar.

These doors can be installed anywhere from walls, doors, sliders to French windows and can be installed by the home handyman, too. Also available are electronic doors made of unbreakable lexan with a four-way setting. It includes a breakaway collar and batteries but locks only in one direction, which could perhaps be a disadvantage.

Infrared pet doors could also be an option. In addition to keeping the house safe, these doors also restrict entry to unwelcome pets from outside. This door comes with two infrared keys, along with the collar and an optional power transformer that allows you to use regular power so that you can save on batteries. Ideal for small pets, these doors can be fitted onto doors of a maximum of two inches depth, or on walls or glass.

Most of these doors have common features like magnetic collar keys, restricting the pets movements, and nearly all of them can be installed on a door, glass, or walls. There is another kind of a door that needs to be fitted onto a panel. These electronic panel doors have the same features as the other electronic doors except that they fit into an assembled panel. The large-size panels have various size and height options. Small and small/medium-sized doors come with collar keys, while smaller keys that are more appropriate for cats can be bought for a bit extra.

Whether one opts for an electronic pet door or an infrared door what matters most is the convenience these doors offer the pet owner and of course, pets, too.
