Vector Pyro - direction of motion
GE patented 4-element Vector pyro-electric sensor
provides:
•
Multi-dimensional signals
•
Effective detection coverage area via 4 interactions
•
Spatial discrimination, significantly reducing the probability of a
false alarm source appearing in both channels in the same
manner
•
Time discrimination, determining the motion of a signal and its
direction as channels are shifted in time
Twice the number of verification points
combined with the channels’ shift in time
proves that the IR source was IN MOTION!

Multi-dimensional signals
•
Conventional pyro’s have 2 elements, connected in opposed polarity,
providing a one-dimensional signal (value)
•
Sophisticated pyro’s have more elements, connected in a variety of
patterns, providing multi-dimensional signals
•
Possible lay-outs for multi-element pyro-electric sensors:
(1) GE patented 4-element Vector pyro.
•
(2) Interleaved structure
The difference in the structure of the elements affects the performance of
the motion detector in 3 ways (see next slide)

GE internal information - Not for external distribution
Effective detection coverage
•
Radiated IR energy is projected by the optics of the motion detector onto the element surface
area of the sensor.
(1) GE patented 4-element Vector pyro
(2) Interleaved structure
•
(1) GE Vector pyros add sensitive elements which preserve the full interaction between radiated
IR energy and element area, resulting in maximum signal strength
•
(2) By dividing the area of a sensitive element into separate elements, the IR energy received
per element is also divided and the signal-to-noise ratio decreases.
More elements required to maintain the reliability in alarm-decision

GE internal information - Not for external distribution
Spatial discrimination
•
A false-alarm source will interact with the sensitive surface area of the pyro and the
corresponding electrical output signals of the pyro
•
(1) GE Vector pyros spatially separate the sensitive elements of the pyro, significantly
reducing the probability of a false alarm source appearing in both channels in the same
manner (and producing identical signals)
•
(2) When elements are interleaved, a false alarm source is always visible in both channels
simultaneously, generating identical signals and verification of one channel with another
cannot help to eliminate these signals

GE Security EMEA

GE internal information - Not for external distribution
Time discrimination
•
The IR radiation of an intruder is projected onto the sensitive area of the pyro’s and the
resulting phase-related signals. Note that since the signals on the left are shifted in time, they
can easily be distinguished from the in-phase signals of item 2 (spatial discrimination),
whereas on the right side of figure 4, the two channels still remain in phase.
•
(1) With GE Vector pyros the intruder interaction with the element surface area at four points
in time instead of two (2).
•
Twice the number of verification points combined with the channels shift in time unmistakably
means that the IR source was IN MOTION!
•
False alarm sources, including stationary thermal sources, can never generate the unique
phase-relation between the elements of the GE Vector multi-element pyro and can therefore
easily be eliminated.

V2E Signal Processing
•
False alarm sources, including stationary thermal sources, can
never generate the unique phase-relation between the elements of
the GE Vector pyro and can therefore easily be eliminated.
•
The sophisticated algorithms, using pattern recognition,
can even determine the direction of motion of the intruder
