Intro to Video Image Detection Based on Machine Vision (video analytics) technologyBased on Machine Vision (video analytics) technology Utilized in: manufacturing facial recognition inventory management product identification
True early detection technology is here…. Old Technology New Technology
Solution The most effective fire detection system is the human being, using visual identification of fire or smoke.The most effective fire detection system is the human being, using visual identification of fire or smoke.

Signifire Video Smoke and Fire Detection Uses visible spectrum video images from stationary camerasUses visible spectrum video images from stationary cameras Analytic process identifies characteristics of flames and/or smokeAnalytic process identifies characteristics of flames and/or smoke Outputs alarms and video to user interfaceOutputs alarms and video to user interface
Reflected Fire Light Filter Filter removes residual light, leaving only light that is originated from flames.
Motion Detection Motion detection is a byproduct of analysisMotion detection is a byproduct of analysis Generally not as sophisticated as security analyticsGenerally not as sophisticated as security analytics Can be tied to image location and scheduleCan be tied to image location and schedule

It takes approximately 20 Spot-type smoke detectors to cover the area of ONE SigniFire camera. Very cost effective in ceilings with beam construction. Very cost effective in ceilings with beam construction. Area of coverage based on 100 = approx. 7800 sq ft Area of coverage based on 150 = approx. 17,600 sq ft
FM Global and UL Recognizes Use of Flame & Smoke VID Systems Flame VID Classified as Radiant-Energy Sensing Detector UL – 268B Video smoke detection FM – Uses FM 3260 (new FM 3232) and UL 268. FM 5-48 (Jan. 2011) Recommends video smoke detection Property/Business Continuity vs. Life Safety
NFPA 72 220.127.116.11 VID and all components thereof, including hardware and software, shall be listed for the purpose of smoke detection 18.104.22.168 VID shall comply with all of the applicable requirements of Chapters 1, 4, 5, 6, and 10 of the code –Chapter 4 power supply criteria –Communications integrity –Listed for the purpose –Alarm signal to FACP 22.214.171.124.1 System Shall be designed in accordance with the performance based design requirements of 5.3 126.96.36.199.2 Location and spacing of VID shall comply with 5.10.5 Prevent tampering and ensure integrity of mission of system.
Visible vs IR Illumination VID systems need illumination either IR or Visible Light LEDs most common due to long life expectancy and low power consumption NFPA 101 requires emergency lighting (1 Foot candle) Switching between IR and white light can result in a focus shift (competition) Blinding of competitor CCD chip with IR IR is not visible to humans –White light provides safety and security
