Get the peace of mind you deserve from the knowledge that you’ll be notified immediately should a door or window be opened surreptitiously in your home. The Long Range Door/Window Sensor works by sending a wireless signal to the Household Alert Receiver (sold separately), which in turn notifies you immediately of the breach with both audio and visual indicators.
