Using the “Time of Flight principle”, the laser sensor continually scans the area by emitting an infrared 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 target, 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 fi lter 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 (refl ections) 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 sensors 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 confi guration, sensitivity and alarm response.

One of the greatest developments 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 effi cient security response.

A game changer

The deployment of lidar detectors looks set to grow signifi cantly.

“And advanced intelligent lidars, are set to change the possibilities available for smarter intruder detection solutions for a range of applications from highrisk and critical infrastructure to large commercial facilities,” concludes Mark Cosgrave.
