Three technologies to watch in fire, life safety

摘要

Many new fire and life safety technologies and innovations remain notable, and they may yet achieve greater use and application in the future. It is possible that some or all of them have achieved greater use in a specific market. There are several current products and systems available today. Video image smoke detection: VISD technology and devices have been available for more than a decade. The concept of VISD is relatively simple: a camera is used to "see" a fire event, which is recognized through the use of video analytic algorithms that analyzes the camera images. Once the algorithm analysis identifies a pattern that is indicative of smoke, an alarm signal is initiated. Video image smoke detection can be accomplished using a stand-alone camera designed specifically for that use, with the ability to perform the analytic algorithms within the camera. The stand-alone cameras can be used for security purposes as well as fire/smoke detectors. These cameras generally can be compared to optical flame detectors, where the processing occurs at the unit and it serves as an advanced spot type detector within a fire alarm system framework.
