Outdoor PIR Protection that covers a building's perimeter: the BX-80N's long, narrow detection area comes from the center point covering both sides. The BX-80N creates a multi-layered, horizontal barrier that detects intruders and sounds the alarm before they actually break in. Just one BX-80N can protect a long area, because it is installed in the center of the detection area and protects on both sides. Boundary Gard makes you feel secure knowing your building is well guarded. 80ft. Long Range Detection Optex's advanced PIR technology creates a narrow, 80ft. long range detection area that protects wide horizontal areas, such as a buildings perimeter. Limited Detection Range Function The detection range of the BX80-N can be adjusted to avoid detecting unwanted objects. Size Judging Function The BX80-N has a layered detection pattern that discriminates between large and small objects within the detection area. Only when both the upper and lower detection layers detect movement, does the BX-80N generate an alarm. High Durable Housing & Lens Metal Guard : MG-1 Helps protect against tampering or vandalism against the unit. Easy Installation Convenient and simple to install, the BX-80N is mounted in the center of the detection area and protects both sides.
