摘要 |
The movement detector has a housing (1) enclosing an IR sensor (2) with several windows (3) in the cylindrical housing mantle each fitted with a collector lens (4). The heat radiation (5) received through each collector lens is focussed onto the IR sensor via a deflection mirror (6) fitted in a rounded housing cap (7) positioned above the IR sensor. The cap is provided with a respective deflection mirror or mirror segment for each collector lens, relatively positioned for covering different sections of the 360 degree field of view.
