Digatech Life Watcher Presence Detector NP LW 01.01

Digatech Life Watcher NP LW 01.01 presence detector is designed for indoor use in office, warehouse, industrial, and similar kinds of security systems for remote detection of presence or absence of a living object in the secured zone.


The sensor is typically installed on a wall or ceiling in the area of interest and is capable to discover evidence of violation of the security policy (such as penetration or attempted penetration) with the transmission of the alarm signal to the control panel. It is possible to invert the alarm function thus making the sensor alarming when there is no living object detected in the room for a certain period of time.

Advantages of the Presence Detector:

  • Sensitivity – the sensor detects very small movements, such as motion of the chest due to respiration, so the sensor "sees" even statically lying, sitting, standing, and of course moving person
  • Sharp boundary of the sensing area – the sensor does not detect objects outside the sensing area
  • Simultaneous operation of several sensors in a single room
  • Ability to hidden installation – the sensor can be installed behind any non metallic panel
  • Easy wall and / or ceiling fastening
