Does a Motion Sensor Dog Barking Alarm Really Work? | 1800Doorbell
Jul 1, 2015 - The motion sensor dog door opener has an infrared sensor that sees your pet and allows them to enter the home
Install a motion detector above the door where the doggie door is installed. You can purchase a sensor that buzzes or makes a sound every time something comes near the door, or one that flashes a special light. In both instances, the alert will keep you conscious of your dog's comings and goings, and also warn you of any threats entering the house.
@Eliot: I do something similar. My dog is almost 18 and is almost deaf therefore he no longer vocalizes to let me know he has to go out to potty. I set up a motion sensor near the back door where he paces, and I have it set to turn on my Sonos. So when I hear Howard Stern, I know my dog is by the back door waiting to go out and if i don’t hurry to open the door, I will have a clean up to take care of. I do have to maneuver the motion sensor behind some furniture so it doesn’t pick up all activity in the room. I wish they would come out with an electronic eye sensor; similar to the type used as a safety with garage doors.
