Infrared Sensor Independent Detection Method for Upper and Lower Sections PB-IN-100AT

An infrared sensor with an independent detection method for upper and lower sections that demonstrates effectiveness in preventing bypassing.

Adoption of a dual response time system To prevent malfunctions caused by small animals or birds and to reliably detect intruders, it is possible to individually adjust the response speed for simultaneous four-beam shading and individual upper and lower section shading. Simultaneous four-beam shading: 35ms to 500ms Individual upper and lower section shading: 100, 200, 300, 500ms Prevention of mutual interference and bypassing! Modulation frequency switching function When conducting linear surveillance with multiple infrared sensors or multi-stage surveillance, it is possible to easily avoid mutual interference and bypassing by switching the modulation frequency of the infrared pulse beam. (Switchable from 1CH to 4CH) Automatically set to optimal sensitivity! Auto gain lock function As long as it is within the maximum surveillance distance, the optimal sensitivity margin is automatically set according to the surveillance distance. Confirmation of gain lock is also easily performed with an electronic sound. Alerting to environmental deterioration! External environment diagnosis function If the infrared light reception level drops below a certain threshold due to dense fog, heavy rain, snowfall, etc., an environmental deterioration signal will be output separately from the alarm signal.
