DIY 2GIG Recessed Door Sensor

by 2GIG

Magnetic contact sensor provides concealed protection for doors or windows. Small design for a hidden professional look. Recessed door or window sensors work similarly to a standard door or window sensors, but can be installed inside the door or window frame to keep them hidden from view.


  • Conceal within a door or window frame
  • Long battery life
  • Good for situations where it is aesthetically preferable to keep the sensor out of sight


The Recessed Door Contact (2GIG-DW20R-345) is the industry’s most flexible supervised door contact. It communicates wirelessly with the control panel via the 345 MHz frequency. It also allows a multitude of applications while hiding the transmitter within a door or window frame. It is powered by a replaceable lithium battery and should last five (5) years under normal usage.
