The principle of operation of Visual Smoke Detection is based on the sophisticated computer analysis of the video image, i.e. the area covered by the CCTV camera’s field of view. With the Fire Sentry VSD system, detection zones can be placed anywhere within the camera view, on or around the areas and items to be protected. The ability to visually verify the alarm condition from the front end processor screen or CCTV surveillance monitor represents a powerful new tool in the very early detection of fire.

Fire Sentry´s VSD-8 Visual Smoke Detection System™ is a world first in delivering early warning of fire at the incipient stage, using cost-effective, tried and tested equipment combined with leading edge image processing technology. This technology has been subject to rigorous scrutiny by the Nuclear Power industry, one of the world’s most demanding applications for fire detection systems.
