Discreetly Monitor any Open/Close Object or Doorway

Monitor a door, window, or other Open/Close object without revealing the sensor's location with the Ecolink Recessed Door/Window Sensor, 433 MHz. This wireless battery-powered sensor installs into a narrow core of a frame of a door, window, cabinet, or other object and informs you whenever the object is opened or closed. When the sensor detects the magnet has moved more than 1 inch, a notification is triggered. The sensor can communicate with compatible receivers up to 100 feet away.

  • 433 MHz sensor discreetly monitors changes in open/closed status of a door/window
  • Battery-powered, no wiring required
  • Reports tamper condition if cover is removed
  • Wireless range up to 100 feet (line-of-sight)
  • DSC compatible
  • 5 year battery life

How It Works

The Recessed Door/Window Sensor consists of two components: the sensor and the magnet. The sensor installs into a 3/4" W x 2.5" hole drilled into the frame, or into the door itself, and the magnet installs on the door/window itself (or the frame if the sensor is installed in the door).
