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 thereby protecting on both sides. Optex's advanced PIR technology creates a narrow, 80ft. long range detection area that protects wide horizontal areas, such as a building's perimeter.
The detection range of the BX80-N can be adjusted to avoid detecting unwanted objects, because 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.
