Widely employed in high risk security applications including banks, museums, airports and rail stations, Eyetec is the first dual motion detector to combine both optical (ODS) and passive infrared (PIR) detection in a single unit.

Reliability is achieved by combining the signals from each of the physically independent sensors and subjecting those signals to sophisticated evaluation and intelligent combination.

Unparalleled false alarm immunity is ensured through a number of features: a new perspective correction facility enables specific areas, such as stairs or raised areas, to be custom configured and effectively screened out from surveillance; black triplex mirror optics filter out light sources efficiently; and ingress from insects or air drafts is prevented by hermetically sealing the Eyetec unit housing.

As with any detector, attention needs to be paid to the issue of tampering and Eyetec has been designed to ensure tamper protection without compromise. An innovative anti-blocking function moves beyond the conventional anti-masking technology which was only effective at close range. With Eyetec any attempt to block detection in the field of view (i.e. the entire room being scanned), whether intentional or unintentional, will trigger a real-time alarm, even when the unit is not armed. Enhanced protection from saboteurs is provided through an integrated back tamper monitoring feature to prevent unauthorised removal of the detector, while continuous monitoring of the detector's functions ensures prompt reporting of any irregularities.

For applications requiring selectable monitoring zones, where areas need to be screened out or surveillance confined to a specific object or area - a museum display being an obvious example - Eyetec can be configured accordingly through its perspective correction function. It can also be programmed to allow a permitted direction of motion, only activating an alarm when someone moves in the wrong direction.

The intelligent camera technology employed in Eyetec records multiple images per second and continuously compares the current image with the previous one, storing an alarm image history to ensure swift and simple evaluation of an alarm event.
