This is a relatively new category of doggy door that has become enormously popular in recent years. It offers one huge benefit that all other passive pet doors lack: selective operation. You see, the problem with passive pet doors is that they open for anyone who wants to push on them. That means other dogs, other cats, raccoons, kids, squirrels, and on and on. Most people generally don’t want those things in their house, they just want their dog or cat to come and go as they please.
Enter the RFID industry. Some marketing genius decided to take RFID, which is a mature technology, and pair it up with a dog door, which is another mature product. The result is a sweet little unit that recognizes your pet and only opens for them. No more neighborhood dogs wandering in your house and getting into your garbage.
The doggy door can be mounted in a wall or just as easily in a door. The package comes with a small transmitter on a collar that your dog wears, and when the transmitter gets in range of the door, it opens up. what a joy!
As part of the very slick control circuitry, the receiver on the door can tell how close the collar is, and also what direction it is traveling in. So if your dog is walking parallel to, or past the door, it won’t open. If they are walking directly at the door it will obediently open and let them in.
The door can also be set to only open on detection from either side, meaning you can set the door to only let your dog out or only let it in. That’s a nice little customization if it’s a nice day and you want your little mutt to play in the backyard and come in when they please, but not go back out.
These are the best things going on the market today. Don’t be afraid to buy one - you won’t regret it.
