FlashBack-2 Compatible Video Motion Detector with Optional
Pre-event Video and Audio Memory Buffer


FlashBack-2 Motion Detector

FlashBack-2 Motion Detector module is designed to provide a rugged, easily installed motion detector capability for the FlashBack-2 range of covert MPEG-2 video recorders.

The module features advanced scene and motion vector analysis, together with user selectable zones, providing highly reliable motion detection. The module is easy to configure via 6 control buttons and an interactive onscreen display.

With standard motion detectors, the delay in detecting motion and then starting a video recorder can be a major problem. The FlashBack-2 Motion Detector Module solves this issue by an internal 7.5 second video and audio memory buffer. When motion is detected, the memory buffer contains several seconds of video before the event, which is then available for recording. The memory buffer time is adjustable so the start of each recording can be at the alarm point, or a few seconds before the event.

The module is housed in a tough milled aluminium enclosure with a rugged hard anodised finish. The unit has two FlashBack compatible 25 way D-Type connectors, so it can be easily installed without any wiring changes.
