גלאי נפח חיצוני וילון דו כיווני מופעל בסוללה אופטקס OPTEX

With long, narrow detection areas that extend from both its sides, the battery-powered BX-80NR is specifically designed to be wirelessly wall-mounted centrally on a building. This unique detection pattern covers the building perimeter with a multi-layered, horizontal barrier that detects intruders before they break in. Included on the unit is a backbox that accepts most manufacturers wireless systems, making the BX-80NR a versatile, stable outdoor PIR requiring no running wire. To help reduce false activations, the range can be adjusted so that detection extends only to the end of the building. The unit also has a size-judging function, which helps it discriminate between large and small objects within the detection area.
