The PetSafe PIRF-100 indoor radio fence is a safe, easy and effective device. You can choose a range inside your home that you want your pet to avoid. Just place the small, disk-shaped transmitter near the area you want to protect, adjust the range from as little as 2 feet and up to 20 feet. When your pet's receiver collar strays into an area that's off limits, the dog receives a warning tone followed by a mild stimulation to remind the pet to move back into the safe zone.
