Our indoor transmitters are small 5-inch units that works seamlessly with our Outdoor Solution using our innovative Computer Collar^®. It sets up in minutes and sends a signal out from its center. You adjust the signal's radius and the signal field to create your pet-free area. When your dog approaches an area he's not allowed to enter, the Computer Collar sounds a warning tone. A few simple training lessons teach your dog to stop when he hears this tone.

The Invisible Fence Brand In-Home Solution allows you to create pet-free area wherever you want inside your home. No more unsightly baby gates. No more keeping all the doors closed. No more keeping watch over the trashcan.

The IFA12 features include:

• Portable design: This small 5-inch square unit can be hidden behind furniture, under stairs, in between floors or mounted on a wall.
• Adjustable signal field: Since the signal field is adjustable, you can protect as specific an area of your home as you'd like, whether it's a valued heirloom, an individual room, or a larger area of the house.
• Great for multiple pet owners who need to allow different pets into different areas of the home.
• The Invisible Fence Brand transmitter is FCC certified, and its unique design will not interfere with other electronic devices.
