Infrared signals are electromagnetic rays having a wavelength higher than that of visible light and cannot, therefore, be seen. Your pet collar key transmits a digital coded infrared signal which is decoded when the key comes within range of your pet door, permitting only pets with keys of same code to enter the house. The range of the key is dependent on the reflection off the immediate surroundings such as your pet's fur, the floor, the pet door, and other walls or surfaces. Infrared signals cannot pass through walls or most other objects, but our patented reflection system will give you approximately 6" of range for the cat door key.Please click on "More Information" for training and further information.
