منارة حضور شرطة التدخل السريع

هناك أسلوبان لتثبيت PIR PRESENCE, أحدهما عبارة عن شريط مزدوج الجوانب والآخر مثبت بمسامير. عندما تستخدم لرصد مكافحة السرقة, the PIR beacon with hall sensor is fixed on the wall while the magnet is fixed on the door frame or window, the distance between the two should be less than 1cm and the installation height should be 2.4m to 3m. And it should be directly aimed at anything whose temperature changes rapidly, especially heating objects such as air conditioners and radiators. علاوة على ذلك,it should also not aimed at the window as the thermal disturbance or personnel movement outside will cause false report. 2.4m to 3.0m.
