Today you can find an electronic pet door designed to be installed just about anywhere. We carry electronic pet doors for walls, for doors and for sliding glass patio doors.
An electronic pet door may use infrared, RFID, ultrasonic, magnetic or electro-magnetic wireless technologies to provide either a fully- or semi-automatic pet door.
Whichever technology is utilized, all electronic pet door brands work in basically the same way. They have sensors that receive a signal from a tiny transmitter on your pet's collar. When the signal is received, the door opens just long enough to let your pet go out or come back in.
When it comes to convenience electronic pet doors can't be beat. Additionally, they prevent other animals that don't belong to you from getting into your home. A traditional manual flap pet door has no such discretion.
