Intro to Video Image Detection



Based on Machine Vision (video analytics)
technology



Utilized in:


manufacturing


facial recognition


inventory management


product identification






True early detection technology is here….

New Technology

Solution


The most effective fire detection system is
the human being, using visual identification
of fire or smoke.




Solution


Signifire uses visual imaging
and artificial intelligence
(machine vision) to emulate
human fire recognition.


“Trained” with 1000’s of real
and false fires.


Analyzes each frame of
480X640 pixels @15
frames/sec


Scans 4.5 million
datapoints

(
luma

value)/second analyzing
the image for signs of
combustion 24/7/365.





Challenge

Detection device challenges for high ceilings:

1.
Spot Smoke/Heat Detectors:

2.
Beam detectors

3.
Aspirating Systems

4.
Linear Heat



Smoke must interact with detection device


Installation, inspection and maintenance on high ladder, lift or scaffolding


Signifire can be installed lower than ceiling level and brings
detection to the fire.

Challenge


Conventional detection devices are not
suitable for many applications having large
volume or high ceilings


Stratification issues


Sprinkler systems designed for building
protection, require a large fire to activate


First responders require early, “actionable
intelligence” to avoid costly fire damage
and injury.


Cause of fires unknown


can rarely make
changes to avoid future incidents






Customized Fire Detection

Reflected Fire Light


Motion


All included on camera


Individually enabled and adjusted


Detect or blocking zones


Sensitivities


Time delay (Alarm verification)


Relay output


On/Off schedules

Targeted Detection

Reduce False Alarms






Signifire Video
Smoke and Fire
Detection


Uses visible spectrum
video images from
stationary cameras


Analytic
process
identifies characteristics
of flames and/or smoke


Outputs
alarms and
video to user interface

Reflected Fire Light Filter

Filter removes residual light,
leaving only light that is
originated from flames.

Coverage Comparison



It takes approximately 20
Spot

type smoke detectors
to cover the area of ONE
Signi
Fire camera.



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

NFPA Journal Aug/Jul 2011

NFPA 72


5.7.6.1 VID and all components thereof, including hardware
and software, shall
be listed for the purpose
of smoke
detection


5.7.6.2 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


5.7.6.2.1 System Shall be designed in accordance with the
performance based design requirements of 5.3


5.7.6.2.2 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


LED’s 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

Common Applications
