Crow D & D Double and Dual Outdoor PIR Motion Sensor

Crow’s D&D is so smart that it can actually tell the difference between a small animal and a genuine intruder.

It’s Double Dual™ optic system simulates 3D stereo vision so it “sees” a wider area and focuses only on real intruders. It’s ASIC technology controls the Double Dual™ elements with supreme accuracy and reliability, and is especially suited for harsh environments.

The D&D’s Double Dual™ Optic System is controlled by a powerful microprocessor which uses Crow’s proprietary digital signal analysis to produce a three-dimensional thermal image of the protected area.

It remembers this image and focuses only on the intruder. It will automatically adapt to environmental changes in wind, temperature and background noise. When conditions change, the D&D’s compensation circuitry automatically adjusts itself to the new conditions, maintaining sensitivity level and detection capability with virtually no false alarms.

The security logic for the D&D is embedded in the ASIC (Application Specific Integrated Chip) component and it can not be violated or decoded, making it perfectly suited for high security applications.

The D&D is available with the standard wide angle lens or optional long range and vertical barrier lenses (see array diagrams); all are interchangeable. The D&D’s water resistant case is especially suited for harsh environments.

This product should be installed by a certified security technician.
