The PIR-TECT's flexible mounting height (up to 20 feet) and adjustable pan (180ø) and tilt (90ø) allow the view of a security camera and the PIR-TECT sensor to coincide, providing more accurate threat detection. A single PIR-TECT device can be programmed for ranges of 30, 65, or 98 feet, thus eliminating the need for multiple devices and reducing costs and inventory.
