Signal and video image processing technologies are widely used in many fields today. Fire detection with video imaging is also a system that uses image processing technology. The basic principle of this system is based on the detection of alarm conditions by analyzing the pixels in the camera image by video analysis. Although it varies according to systems and manufacturers, today it is possible to detect smoke, flame, reflected flame and oil leaks with a camera and central server.
The use of video imaging technology in fire detection systems has also continued its rapid development and has taken its place in international standards. Fire detection systems with video imaging, first defined in the 2007 version of NFPA 72, have ceased to be complementary systems today and have started to be used as primary detection systems.
Especially in areas where the installation and use of point type detectors is difficult due to factors such as large area, detection distance, height, dust/dirt, etc., detection with video imaging technologies has shown successful results. VFD systems are also accepted and classified by UL and FM organizations. While American standardization and certification bodies include VFD systems in their literature, signaling that their widespread use will increase in the future, it has not yet found a response in EN, the European standardization.
EN is continuing its studies and tests on this subject and is considering to include VFD systems in future revisions of EN-54.
BS, the UK standard, has included VFD systems in the “Section 21.1.3 Smoke Detectors” of the “BS5839-1:2002+A2:2008 – Code of Practice for System Design, Installation, Commissioning and Maintenance” standard. In this article, it is stated that smoke can be detected by imaging techniques using a closed circuit camera system in the protected area.”
Even a small fire can have big consequences, both in high-impact (e.g. airplane hangars) and high-risk environments (e.g. chemical plants). Traditional smoke detectors might only get activated when the damage is already done.
FireCatcher operates flawlessly in environments where chemicals, dust or vapor are present every day. Unlike traditional smoke detection systems, FireCatcher does not generate false alarms because of these phenomena.
FireCatcher is ideal for use in tall buildings or large indoor spaces. In these environments, smoke might never reach your traditional smoke detector, because of a process called stratification, which stops the upward movement of smoke.
