Reliable PIR Motion Detection Rain or Shine

The VX Infinity Dual PIR Motion Detector with Anti-Masking (Inovonics Compatible) eliminates false alarms caused by small animals with its dual motion detection zones. The iSeries of VX Infinity Dual PIR Motion Detectors come with pre-installed Inovonics EN1941 transmitters for easy connection to Inovonics receivers and minimum electrical current consumption from a battery.

  • Dual PIR detection sends alerts when both zones are triggered
  • Senses motion up to 40 feet away in a 90-degree field
  • Built-in Inovonics Transmitter for quick connection to Inovonics receivers
  • Sensitivity adjustment switch for customized detection zones
  • IP55 protection and UV resistant ASA casing
  • Multipurpose back box for spacing or housing of wireless transmitters
  • Active IR Anti-Masking detects objects covering the lens

This Dual PIR sensor sends alarms when both detection zones are triggered. Integrated SDMA logic accounts for climate changes and wind-swept vegetation to further refine movement detection capabilities in any outdoor environments. IR Anti-Masking detects objects covering or obstructing the sensor's lens.

Installation Details

The Dual PIR Motion Detector can be screw-mounted onto most surfaces with the included mounting plate. Simply secure the plate onto a wall and mount the Detector and Backbox. Alternatively, the detector can be pole-mounted by using a band less than 25mm wide. Place compatible wireless transmitters into the Back Box for protection from the elements.
