More Info

Microwave Technology
(Patent Pending Area Shaping Technology)
Optex has created a breakthrough in Microwave Detection. This DX series reduce one of the biggest weak points of microwave detection, that is the penetration of walls and unwanted detection of movement outside the coverage area. In addition, the detection area has uniform sensitivity which minimizes false activations caused by spot movement in the detecting area, i.e.small animals. The DX series is new dimensions in microwave technology.

Passive Infrared Technology
(Patented Quad Zone Logic)
By utilizing Optex Advanced Optical Technology, the DX-40/60 create evenly distributed sensitivity throughout the detection area. Accurate focus creates even sensitivity and high resistance to spot temperature changes. Other detectors may have inconsistent detection creating hot spots (false alarm can occur) and dead spots (no detection). In addition, the New Spherical Lens contributes to a superior aesthetic appearance.

Detection Area Size Configuration
(Microwave Area Shaping Technology and Quad Zone Logic)
The Microwave Area can be easily shaped to fit the desired area and have even sensitivity. In addition, Quad Zone Logic in the PIR provides high tolerance to spot temperature changes and movements caused by small animals, heating vents, moving curtains and vibrations caused by big machinery.
