The SRPG2 combines quad PIR technology with advanced dual-tech glassbreak technology. This will provide a time saving, cost effective alternative to installing two seperate devices. The glassbreak portion uses a unique phased frequency circuitry which allows detection of both shock and glass breakage creating a high level of immunity to false alarms. This detector is combined with our PIR containing Crystal Vision technology. This technology is known to be five times more efficient than a traditional "soft fresnel" lens.


  • Specially designed, two detectors in one housing

  • Unique dual element pyro-sensor & hard spherical lens for outstanding detection,performance and elimination of false alarms

  • Shock and breakage detection with separate sensitivity adjustments

  • Allows detection of several windows with one detector

  • Unique signal analysis ignores environmental disturbances

  • Seperate relay outputs for PIR & glass breakage
