Notifier, a part of Honeywell Fire Systems, is offering Video Smoke Detection (VSD) as part of its line of fire and smoke detection products. VSD is based on the computer analysis of video images provided by CCTV cameras. It uses standard CCTV cameras linked to a self-contained processing system which is capable of recognizing smoke and flame patterns within the video image. The system uses sophisticated software algorithms to automatically identify the specific motion pattern of smoke and fire while ignoring other on-screen movement patterns from up to four cameras simultaneously. When fire or smoke is detected, the system alerts the operator both at the operating terminal and at an unlimited number of remote locations. The system is designed for applications where traditional smoke detection technologies may be impractical or inefficient - such as large open areas, very high ceilings or high air flows that can prevent smoke from reaching a spot-type smoke detector, thereby delaying alarm activation.
