Originally developed for mapping and surveying, LIDAR (Light Detection and Ranging) has found an essential niche in security, offering unparalleled capabilities in proactively detecting threats. OPTEX pioneered the use of LiDAR as an intrusion detection technology and has led the way for more than a decade using laser scanning capabilities to protect high-value assets and critical facilities. As we approach the introduction of our latest LiDAR solution, we take a look at how the technology works and how we got to where we are today.

How it works

LIDAR technology uses laser light to measure distances and create detailed maps of environments. Think of it like a high-tech radar, but instead of using radio waves, it uses light waves. The LiDAR or laser scanner emits an infrared beam of light and measures how long it takes to return after hitting a certain object. The time between the exit and return of the beam (commonly referred to as Time-of-Flight) allows the sensor to capture, every second, millions of distance measurement points from which it can identify the size and behaviour of objects, and accurately track their movement within the detection zone.

Compared to other technologies, LiDAR is not affected by lighting, temperature changes, or weather, factors that considerably increase its reliability as an intrusion detection technology that can be used both in very dark indoor environments (such as false ceilings or tunnels) or outdoors in extreme weather conditions. The LiDAR detection area is defined as an invisible (virtual) thin curtain or ceiling where very high-resolution scanning occurs.

OPTEX’S LiDAR History

OPTEX launched its first LiDAR sensor, the REDSCAN RLS-3060, back in 2009. The long-range 2D detector quickly proved its capabilities to identify a moving objects size, location and distance, being successfully deployed across a variety of settings, from underground stations to critical infrastructure.

The REDSCAN mini series (RLS-2020S and RLS-2020I models) followed in 2016, featuring fully customisable detection within a 20x20m area with up to four independent zones that can be seamlessly integrated with existing security systems. Its innovative features and functionalities were recognised at the Benchmark Innovation Awards in 2017.

Fast forward to 2021 and OPTEX launched its new and improved REDSCAN Pro sensor series across EMEA, specifically designed to meet the needs of high security sites and installations that require a greater level of customisation. Featuring our longest detection range yet (up to 50x100m), the sensors feature a rectangular detection pattern (instead of fan-shaped) to protected facades, roofs and building perimeters. Through the ONVIF protocol (Profile S), the REDSCAN Pro allows sending alarm outputs and the video stream from the device to any ONVIF-compliant video system in the network or to connected devices.

Since launching, the REDSCAN Pro has been recognised with multiple prestigious industry awards, including Detektor International Award in October 2021, selection by SICUR for the Innovation Gallery 2022 and Perimeter Security Product/Service of the Year in the Intersec Dubai Awards 2023.

The LiDAR journey in the OPTEX portfolio goes on, with the new generation of REDSCAN sensor due to be announced very soon.

Useful Application of REDSCAN series

REDSCAN mini and REDSCAN Pro sensors can provide advanced security in each key layer of a site: the perimeter, approach, building, and interior. Designed to work in both indoor and outdoor, and short and long-range applications, the sensors can be mounted horizontally to create virtual planes to protect roofs, skylights, and ceilings and vertically to create virtual walls to protect high-value assets, walls, or facades. Moreover, different environments require different solutions. For this reason, there are different models to guarantee the right answer to the specific need of the site needed to be protected.

Thanks to their unique features, efficacy, and adaptability they are perfect to protect critical infrastructure and high-security sites; access to logistics centres where there is a need to discriminate against passing vehicles or trucks but alert to the passage of people, transport infrastructure and tunnel protection; asset protection, for instance in datacentres, museums, warehouses, and locations with high-value assets.

Conclusion

The use and application of LiDAR technology within the security industry continues to evolve, and it can play a vital role in enhancing safety and protection. Its ability to provide detailed environmental insights, detect threats, and facilitate rapid responses has redefined the landscape of modern security solutions. As LIDAR technology continues to advance and integrate with other innovations, OPTEX remains at the forefront of leveraging its full potential, contributing to creating safer environments for individuals and communities around the world.
