SimpliSafe Entry Sensor (SS3-ENTRY)

SimpliSafe Entry Sensor is easy to install on every type of door or window. The magnet goes on the door or window, and the sensor goes on the frame (or vice versa). Magnet can be placed up to 2 inches from the sensor, so sensors fit on all types of doors and windows. SimpliSafe sensors come with the battery pre-installed and adhesive tape pre-applied, making set-up a snap. When your system is OFF and a door or window opens, the Base Station will sound a door chime so you'll know if someone is entering. The sensor detects whenever the magnet moves more than two inches away from it—so it knows whenever the door or window opens. The Entry Sensor is compatible with a SimpliSafe security system and features a magnet moves detection; fit on all types of doors and windows; mounting hardware included. Pro tip: Stop burglars where they break in most. Ground floor doors and windows. For rooms with 3 or more windows, consider a Motion Sensor instead.
