How does an Invisible Fence system work outdoors?
Very simply, a wire is concealed around the perimeter of your property, establishing your pet’s Invisible Boundary®. A transmitter hidden in an out-of-the way location – like a basement or garage – sends a radio signal along the wire. The radio signal is picked up by your pet’s Computer Collar®, which emits a warning sound when he approaches the Invisible Boundary. Through Safe Dog® training your dog learns to obey the signal and stay within the established boundaries.
