OPTEX has 2 different detection logics, Quad Zone Logic and Milti-Focus Optics. Each logic creates high vertical density detection zones by original optical technology to prevent false alarms.
High Vertical Density Detection Zones of Quad Zone Logic and Multi-Focus Optics
Normally, a detector uses twin elements create two detection zones but Optex's detectors create an extremely high vertical zone density, two or three times the size of that in conventional PIRs. These taller zones capture the entire body mass of a person and enable detection of the smallest temperature contrast between them and the background.

Detection Logics
Multi-Focus Optics
In ordinary residences and offices, there are desks, shelves and other furniture. When these objects hide a part of the body, it may make detection difficult.

Quad Zone Logic
Optex utilizes another technology, "QUAD Zone Logic in order to achieve the highest resistance against false alarm sources like pet and small animals.
Quad Zone Logic generates more detection zones thereby increasing the density of the coverage area. This greatly enhances the sensors ability to discriminate between people and small animals.
For example, in the shorter distance, the highly dense, multiply segmented zone pattern requires 4 to 8 zones to be broken by human sized objects. At the furthest ranges, 2 or more zones captures the humans, while small animals may affect one or only part of one zone.
