Southwest Microwave has been known for proven perimeter detection technologies, including fence detection systems, buried cable systems, and microwave detection. These technologies have been trusted in demanding environments because they are built for reliability, long service life, and consistent performance.
But perimeter security is changing.
In a recent discussion with Tom Fontana, Jeff Drews from Southwest Microwave explained how LiDAR is adding a new layer of intelligence to the perimeter security conversation. Rather than replacing proven technologies such as microwave or fence detection in every application, LiDAR gives system designers another powerful tool for sites that need more precision, more programmability, and more target classification at the edge.
Southwest Microwave’s INTREPID™ LiDAR Series is designed around solid-state LiDAR technology. That means it has no moving parts, captures movement in three dimensions, and performs detection, tracking, and alarm functions directly at the sensor. For security-sensitive facilities, this combination can help reduce nuisance alarms, improve situational awareness, and simplify deployment.
Traditional microwave perimeter detection is highly effective, especially in harsh outdoor environments. However, a microwave field is generally a detection field. It is excellent at detecting activity within that field, but it does not classify targets in the same way a LiDAR sensor can.
LiDAR works differently. Instead of creating a microwave field, LiDAR sends light energy into the monitored area and measures reflected energy from objects and targets. That allows the system to build a more detailed understanding of what is happening inside the detection area.
This opens up several important capabilities for perimeter security:
You can create narrow detection areas.
You can build exclusion zones.
You can focus detection on specific areas instead of treating the entire scene the same way.
You can classify different types of targets.
You can reduce alarms from targets you do not care about.
For example, if a site does not want to alarm on small animals, a LiDAR sensor may be programmed to help exclude those targets. If a site only wants to alarm on people or vehicles, the system can be configured around those target types. This gives security teams more control over what creates an alarm and what does not.
One of the most important points is that the INTREPID LiDAR sensors perform processing directly at the sensor.
That matters because LiDAR can require significant processing power. In some systems, the sensor may be located at the edge, but the actual processing happens elsewhere, such as on a server or in the cloud. That can introduce additional infrastructure, added cost, network dependency, recurring fees, and added complexity.
With INTREPID LiDAR, detection, tracking, and alarm functions are executed directly at the sensor. This edge-based approach can help simplify deployment and reduce the need for separate processing infrastructure. It also makes the cost structure more straightforward because the sensor is not dependent on a separate cloud service or server for its core detection logic.
For integrators, consultants, and end users, that is an important design advantage. It allows the LiDAR sensor to be treated more like a self-contained perimeter detection device rather than a field device that depends on a larger backend processing environment.
Another major differentiator is the solid-state design. Many LiDAR technologies use moving mirrors or rotating mechanical components to scan an area. Moving parts can create long-term reliability concerns, especially in perimeter security environments where devices may operate outdoors, continuously, and in challenging weather conditions.
The INTREPID LiDAR Series uses a semiconductor-based, solid-state design with no moving parts. This supports continuous 24/7 operation with minimal maintenance.
This also gives designers more flexibility in how the device is mounted and oriented. Jeff Drews explained that because the device is solid state, it can be turned or positioned to change how the field of view is applied to a detection area. That can be useful in applications where the designer wants to encapsulate a specific zone or align the sensor with a unique perimeter geometry.
The INTREPID LiDAR Series is described as providing high-resolution 4D detection. In practical terms, the sensor maps the environment in three physical dimensions, then adds time as the fourth dimension.
That matters because security is not only about where something is. It is also about how that object moves over time.
With 4D detection, the system can help determine target size, movement, position, and behavior across time. This makes it possible to track and classify targets more intelligently. In the transcript, Jeff explained that a person, animal, or vehicle can be identified as a different class of target, and the system can be configured to alarm only on the types of targets the site cares about.
This is especially valuable for perimeter applications where nuisance alarms can overwhelm operators. For example, a facility may want to ignore dogs, reduce alarms from certain vehicle movement, or prioritize human activity in a specific zone. Instead of simply detecting motion, LiDAR gives the system more context.
Apex: Up to 100 meters
Vector: Up to 150 meters
Horizon: Up to 300 meters
The models are not only different in range. They also have different fields of view and angular resolutions. Apex has an 80° x 22° field of view, Vector has a 45° x 13° field of view, and Horizon has a 22.5° x 6.5° field of view.
That means the right model depends on the application. A wider field of view may be useful for shorter-range coverage, while a narrower field of view may support longer-range detection and higher point density.
This is important because perimeter security design is not simply about choosing the model with the longest stated range. It is about choosing the right sensor for the target, the environment, the zone layout, and the detection requirement.
One of the most valuable parts of the discussion was Jeff's explanation of range.
The stated maximum range of a LiDAR sensor is not always the same as the best design range for a real-world security application. LiDAR range depends on several factors, including target size, reflectivity, weather, zone setup, and detection requirements.
Jeff explained that larger and more reflective targets can be detected at longer distances. Smaller or lower-profile targets may require more conservative design assumptions. For example, he noted that if the application requires consistent detection of walking targets in inclement weather, the practical design distance may be significantly less than the maximum range. If the requirement involves detecting a crawling target, the design distance may need to be reduced even further.
This is a critical point for consultants, integrators, and end users. Perimeter detection should be designed around the threat profile, the environment, and the performance requirement, not only the maximum range printed on a data sheet.
The INTREPID LiDAR Series is designed for simplified installation using PoE, allowing a single Ethernet cable to carry power and data.
From a system design standpoint, that makes deployment more familiar for modern security integrators. The sensor connects to the network, can be installed on a pole or fence line, and can be incorporated into broader security systems.
In the discussion, Jeff also referenced integration options including ONVIF, MQTT, relay boards, Southwest Microwave modules, and common VMS environments such as Genetec and Milestone. This gives designers multiple paths for incorporating LiDAR alarms and detection data into the broader security ecosystem.
Another important feature is the ability to classify and track targets.
Jeff described how a target can be walked through the detection area so the system can learn the parameters of what to look for. In that sense, the system can be configured around the real needs of the site. He also explained that the system can distinguish and track separate targets moving through the same area.
That is a major advantage in complex perimeter environments. Instead of treating every object the same way, the system can help differentiate between target types and apply alarm logic accordingly.
For security teams, this can support better alarm quality. For integrators and consultants, it creates more flexibility when designing around a site’s specific risks.
INTREPID LiDAR is a strong fit for applications where precision, classification, and zone control are important. That may include critical infrastructure, utility sites, correctional environments, transportation facilities, industrial properties, and other security-sensitive locations.
It can be especially useful where the site needs to:
Monitor specific perimeter zones
Reduce nuisance alarms
Classify humans, vehicles, or animals
Create exclusion areas
Detect activity in narrow or constrained spaces
Add intelligent detection near gates, fence lines, or open areas
Integrate detection into a larger VMS or alarm system
Like any perimeter technology, LiDAR should be applied carefully. Weather, target type, mounting location, distance, and detection expectations all matter. But when designed properly, it gives security teams a more intelligent and programmable way to monitor the perimeter.
Southwest Microwave’s INTREPID LiDAR Series represents a practical next step in perimeter security detection. It builds on the company’s long history of perimeter protection while adding modern capabilities such as solid-state reliability, edge-based processing, 4D detection, target classification, PoE installation, and flexible system integration.
For sites that need more than basic detection, LiDAR can provide valuable context. It can help security teams understand not just that something entered a detection area, but what type of target it may be, where it is moving, and whether it should generate an alarm.
That distinction is what makes LiDAR such an important technology for the future of perimeter security.
Southwest Microwave INTREPID LiDAR is a series of PoE solid-state LiDAR sensors designed for perimeter security. The sensors use advanced LiDAR technology to detect, track, classify, and alarm on activity directly at the sensor.
Traditional microwave detection creates a detection field, while LiDAR uses reflected light energy to map and analyze activity in a detection area. This allows LiDAR to support target classification, exclusion zones, and more precise detection logic.
