The Optex VXS-DAM Outdoor 90° Dual-Tech PIR includes an integrated algorithm of both passive infrared and microwave technology for optimal stability in detection performance. In environments where strong sunlight hits the land, or environments facing direct light beams from traffic, the VXS-DAM works highly accurately to ensure false alarm immunities.

The VXS-DAM is equipped with a digitally enhanced signal recognition logic called SMDA. By analyzing detection patterns and environmental information, SMDA improves immunity against various noise factors such as climate changes and vegetation sways, and can distinguish between the cause of nuisance false alarms and genuine intrusions.
