Reliable Boundary Detection Coverage With Anti-Masking

Provide enhanced and reliable outdoor motion detection of windows and boundary areas of your home or office with the Optex BX Shield Outdoor Boundary Detector (Anti-Masking Model). It features four PIRs (two on each side of the detector), an adjustable detection range of 8ft to 40ft (per side), and Logic Function, which will only trigger an alarm signal when the upper and lower detection areas detect movement at the same time.

  • IR Digital Anti-Masking detects when the lens surface has been covered
  • Detection security of window, boundary, and long narrow areas
  • 8 feet to 40 feet adjustable detection range (per side)
  • Logic Function triggers alarm when both upper and lower areas are detected
  • SMDA Logic: differentiates between false alarms & genuine intrusions

Individual Left/Right High Sensitivity Detection Settings

The Optex BX Shield Outdoor Boundary Detector can trigger alarm signals on both the left and right side individually of long narrow areas of your property. The PIR sensors (2 per side) can differentiate between large and small objects within the detection area, minimizing chances of false alarms. The detection distance can also be adjusted between 8ft to 40ft.

Reliable Detection

  • The IR digital anti-masking function helps detect when a covering object, such as tape, is on the lens surface.
  • SMDA Logic (Super Multidimensional Analysis) technology can differentiate between climate changes and vegetation sways and actual intrusions.
  • An alarm signal is only triggered when movement is detected by both upper and lower detection areas.
  • Extreme High Detection Mode increases PIR sensitivity to prevent missed alarms caused by small temperature differences between the background and a human body.
