2023 - Multilayered - Perimeter

The perimeter is the first line of defence against intruders which is why it's so important to get it right with reliable intrusion detection. Whether you have a physical perimeter or not we have sensing technologies to fit any site and detect potential threats.

At OPTEX we advocate multi-layered protection, starting from the perimeter. Sites that rely solely on cameras for their perimeter protection often underestimate the difficulty and cost of nuisance alarms. Therefore, adding that extra layer of intrusion detection to accurately alert when an intruder is approaching or crossing the perimeter is much more reliable and helps to warn of potential threats or loitering in the outermost zones.

Fiber Optic

Fiber optic technology is a fantastic choice for protecting larger sites, our FiberSensys for example ranges from 50m-100km, and is not affected by weather conditions or lighting. Fence-mounted fibre optic sensors work by installing optical fibres along the perimeter of the protected area, and monitoring changes in the light transmitted through the fibres. Any attempt to breach the perimeter, such as climbing or cutting the fence, will cause a change in the light transmission and trigger an alarm.

Fibre optic sensors are intrinsically safe for use in hazardous areas and are designed to operate in extreme temperatures as well as in dusty or harsh environments, making them suitable for a wide range of locations including critical infrastructure, industrial facilities, government buildings, and other sensitive areas. They can also be integrated with other security systems, such as video surveillance cameras and access control systems, to provide a comprehensive security solution.

LiDAR Technology

LiDAR technology uses laser beams to measure distances and can detect intrusions by measuring changes in the environment over time. Our REDSCAN LiDAR technology enhances your physical security by being able to create virtual walls and ceilings. With REDSCAN you can create multiple zones and set different requirements for each one. With advanced analytics our REDSCANs can analyse the size, speed and distance of the moving objects. It also provides accurate point detection by tracking the X & Y coordinates of the moving objects, allowing you to know exactly where the intruder is.


The REDSCAN Pro series are ONVIF compliant and provide high-security protection over large areas up to 100m. The REDSCAN Pro also has a built-in camera to assist with configuration and post-event analysis, delivering the ultimate solution and accuracy when it comes to intruder detection by recording the exact events as they happen. It offers up to 8 independent zones which can be individually adjusted to detect different object sizes, for example one zone can be set to protect the gate and detect just vehicles while another can detect people.

Active IR Beams

Active Infrared beams (AIR) provide a detection line that can be used as a virtual wall or placed on top of existing walls or fences giving them an additional virtual security line, or added inside the fence line further bolstering the physical perimeter line. They also work for open perimeters in sites where fences and walls are not possible. We have a variety of infrared beams ranging from the AX series for shorter distance and the SL series for long distances of up to 100m.

Another advantage of active IR beams is that there are wireless models available, making them easy to implement in temporary sites. They can also be stacked in beam towers to create a taller and more secure perimeter which will be more difficult to evade. The beam towers can contain multiple sets of air beams facing in either direction to connect with other towers and create an end-to-end virtual perimeter around the entire site.
