Using the "Time of Flight princi-
ple", the laser sensor continually
scans the area by emitting an infra-
red pulse which reflects back to the
sensor once it hits an object.
"The sensor can accurately
detect people and objects providing
the X and Y coordinates for any tar-
get, calculate the real-time location
and speed of movement, enabling
a smart tracking point-detection
security system," states Mark
Cosgrave, Divisional Manager at
Optex.
Complex analysis
Evolution in processing power
means that lidars are now able
to process a larger quantity of
data and perform more complex
analysis.
"Sophisticated lidar detectors,
such as the award-winning Optex
Redscan Pro, features advanced
processing capacity to analyse
environmental signals and filter
out noises created by challenging
environmental conditions, such as
heavy rain, snow sleet and hail to
maintain stable detection," stresses
Mark Cosgrave.
"It also analyses multiple echoes
(reflections) from a suspicious
object within a fraction of a second,
validating each echo to ensure a
detection is not fooled by weather
conditions. Additionally, the sen-
sors can dynamically adjust the
detection area to changes in the
terrain, such as accumulation of
snow or leaves."
Smarter intruder detection
Mark Cosgrave also claims that
improved processing power also
gives the ability for the sensor to
provide multi-zone logic where
the detection area can be divided
up to as many as eight detection
zones, each with independent con-
figuration, sensitivity and alarm
response.
One of the greatest develop-
ments in sensing technologies is
the fast and highly accurate point
detection which lidar can provide
thanks to its quick onboard
processing and data capture. When
used with a security platform,
lidars can improve monitoring and
enable a rapid and efficient security
response.
A game changer
The deployment of lidar detectors
looks set to grow significantly.
"And advanced intelligent
lidars, are set to change the pos-
sibilities available for smarter
intruder detection solutions for a
range of applications from high-
risk and critical infrastructure
to large commercial facilities,"
concludes Mark Cosgrave.
In recent years, Lidar technology has become more
prominent in the security sector. Originally used for
the automation and measuring industry, it has been
developed and improved by some security manu-
facturers to become one of the most accurate and
precise intrusion detection technologies available.
