OPBXSST
The Optex BX Shield Outdoor Boundary Detector (Standard Model) provides enhanced and reliable outdoor motion detection of windows and boundary areas of your property. 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.

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.
