Control your pet inside your home with our PetSafe Indoor Wireless Invisible Fence. The Indoor Wireless Invisible Fence is a simple to operate system designed to keep pets away from designated areas specified by the user. This system can be used to keep your pet away from a certain room, away from a sofa, table top, etc. by simply placing the transmitter near the doorway or under the sofa or wherever. Although the transmitter is designed for indoor use, it can be used in a garage or under a covered patio where a 110 outlet is accessible.

Just place the small, disk-shaped transmitter (about the size of a Frisbee) near the area you want to protect. The transmitter plugs into a standard outlet and emits a radio signal which is picked up by the lightweight receiver worn on your pet's collar.The range adjustment dial (also ON/OFF switch) determines the distance from the boundary that the receiver will pick up the signal. The range is adjustable from 2 feet to over 10 feet in each direction from the disk depending on the surface the transmitter is on. Adjusting the dial to the right will increase the signal range. When your pet gets near the signal, a warning beep sounds on the receiver worn on your pet's collar. Your pet responds to the transmitter’s stimulation through 2 contact points on the receiver collar that touch your pet’s neck. If your pet continues to approach the protected area, he or she receives a mild static correction which is startling but not harmful.

Each PetSafe Indoor Wireless Invisible Fence Transmitter is good for as many pets as you have. You will just need an extra receiver for each additional pet. You can contain an unlimited number of pets with this fence system as long as each has his/her own collar/receiver.

You can set up as many separate protected areas as you need in separate parts of your home. All you will need is one of our IRF-100M Indoor Invisible Fence Transmitters for each area to be protected. The same collar/receivers are compatible with each IRF-100M Indoor Invisible Fence Transmitter (as well as with our outdoor Invisible Fence Transmitters) no matter if your pets run from one protected area on one side of your house to another on the other side or on a different level or even outside of the house for that matter if you have one of our outdoor Invisible Fence systems in place.

Each IRF-100M Indoor Invisible Fence Transmitter can be set for a different range from as little as a 2 foot radius (which equals a 4 foot diameter) to up to a 10 foot radius (which equals a 20 foot diameter). The radio signal will also travel through walls including brick.

Safety features:

Digitally coded signal to prevent false activation. Only our transmitter can activate the receiver. Other brands' receivers can be activated by televisions, cordless phones, garage door openers, etc. We use filters and coded signals to prevent this. Don't trust your pet's safety to anything but a PetSafe™ Containment System. Our receiver is Fail-Safe. If your pet gets trapped in the correction zone, the receiver will shut down after 20 seconds to prevent overcorrection. The only UL and CE rated system on the market.


Which Indoor Wireless Invisible Fence Kit Should You Get?


If your dog is over 30 pounds and is extremely stubborn or hard to train, you may need our Indoor Wireless Invisible Fence with Stubborn Dog Receiver. The Stubborn Dog Receiver has 5 levels of correction plus vibration in the warning area for an added deterrent and a low battery light to let you know when to replace the battery.  Some breeds need the Stubborn Dog Receiver even though they may not necessarily be hard to train. Our experience has been that Labs, Shepherds, Akitas and similar breeds often need the Stubborn Dog Receiver. This is usually due to these breeds being less sensitive to the correction due to thick skin and/or thick fur.


We recommend our Indoor Wireless Invisible Fence with Deluxe Ultralight Receiver for any dog or cat that is 5 pounds or over. With 5 levels of programmable correction and a low battery indicator light to let you know when to replace the battery, this is our most versatile and advanced receiver. You can increase or decrease the correction to meet your pet's training needs. At level 5, the Deluxe Ultralight Receiver is strong enough for most hard to train dogs.


We recommend our Indoor Wireless Invisible Fence with Standard Ultralight Receiver for easy or average to train small to medium size dogs 5 pounds or over. The Standard Ultralight Receiver has 1 correction level, similar to level 3 on our Deluxe Ultralight Receiver.

*Should you have another pet, depending on his or her breed, age and weight, you may decide that the collar/receiver from one of our other compatible Invisible Fence systems would be more appropriate for your other pet. It is no problem to mix and match. To custom order this system by adding collar/receivers from any of our compatible Invisible Fence systems different from the one which comes with the system described on this page, please contact us prior to purchase at

Please note that all of the collar/receivers used by each of our PetSafe brand outdoor and indoor Invisible Fence systems are all cross-compatible with each other.

Our Instant Fence Receiver is not compatible with any of our other outdoor or indoor Invisible Fence systems.
