Wirelessly Detect Intruders or Events From the Outside: Finally, the ability to quickly link the outside of a home to the way your customers live and expect. With the FITLink, give real coverage to driveways, outdoor living spaces, entryways, garage & sliding doors, or even side yards & gates. Get notifications with chimes, on smart phones or even trigger cameras through panels' connected services and existing keypads at a cost of traditional indoor sensors with the same installation convenience. (Battery and wireless transmitter included.)
