SERVAL-6M Single-position microwave security sensor

New product

Designed for effective extrusion detection the single-position microwave sensor covers the area of 70 m2 (753 ft2). The alarm signal is triggered (normally closed loop) when a person's movement is detected.

Ideal for indoor and semi-outdoor installations. The sensor can be used in an area with active air circulations (storages, warehouses hangars, etc.) and can be masked by radio-transparent materials such as plastics, plywood, gypsum, etc.

The Doppler effect microwave detection algorithm guarantees equal movement sensitivity within the whole volume of the covered zone.


  • Ideal balance between functionality and affordability.
  • Improved noise immunity thanks to the state-of-art linear frequency-modulated scanning signal.
  • Convenient sensor’s sensitivity adjustment.
  • Built-in power supply monitoring.
  • Internal tampering attempts detection sensor.
  • Compact form-factor.

Designed for real-life conditions

  • Not sensitive to movements of single small animals.
  • Built-in electromagnetic noise protection including high-voltage power lines and flashes of lightning.
  • The sensor ignores sitting or standing person making short movements within +/- 0.2 m (1 ft.)
  • Wide range of supported power supply voltages.
  • Protected against interference with other microwave sensors.
  • Electrically protected signal and power lines.
