“A moment's delay can lead to a disaster, but early warning can save lives, ” said
Eric Chen, VFDS Product Manager, GKB Security.
“We know that where there's smoke, there's fire. But quite often, by the time smoke sensors detect the flames, there is not much response time left. Therefore, GKB saw the need to incorporate video image detection (VID) technology into early detection, so smoke and small flames can be brought to attention at soonest before developing into a big fire.”
“GKB's Video Fire Detection System has been out for 7 years now, and we keep on improving to better service our clients. The system is most critical for outdoor and spacious indoor/semi-indoor areas where smoke detectors are not easily installed, like power plant, cotton storage field, chemical/petroleum/oil storage sites, air hangars, nursing homes, and many more.”
Chen described with a success story in Australia's air hangar. “The ceiling of the hangar is so high that it would take a longer time for smoke to be picked up by detectors mounted on the ceiling. Therefore, it became necessary to safeguard the hangar with a VFDS server that analyzes video feeds from 8 cameras. The VFDS is also connected to a fire control panel so when suspicious images are determined, immediate notification can be sent to the attendants showing where, when, and how the smoke/flame happened for further action.”
Pre-determined smoke and flame lines can raise detection rate and lower false alarm rate. Careful calibrations can lower the false alarm rate per channel to be 2 times/month.
