|PlexiDor Electronic seen from the outside|
The door is controlled through an RFID key attached to the pet's collar.
The image to the right shows what the door looks like outside the house. Below is a short video showing the inside, and the function of the door. Sorry it's a little blurry. The video is from the Global Pet Expo - it's hard to keep a camera still in a place like that. ;-)
We put the key in the opening to make it go up and down.
