Intrusion Detection

Argu adds perimeter security that understands distance and depth, flagging a fence violation the moment someone starts to climb, not after they are inside.

The differentiator is spatial perception. Standard motion sensors see pixels change and cannot tell a swaying branch from a person at the fence line. Because this system understands depth and three dimensional boundaries, it holds up at night and in adverse weather, conditions where pixel based motion sensors tend to produce the most nuisance alarms. Remote unmanned sites depend on perimeter agents as the first layer of critical infrastructure security.

Key facts:

Distance-to-fence tracking runs on existing RTSP or ONVIF Profile S/T camera streams at 1080p–4K, 15–30 fps.
Outdoor camera hardware rated IP66/IK10 continues reading through night, rain and fog.
Power and data run over existing 802.3af/802.3at PoE, up to 100m over Cat6, without new poles or trenching.
Fence-line video and the distance/behavior read can be retained together on an operator-set 30–90 day window.
Perimeter monitoring at utility and maritime facilities maps to the physical-security intent of NERC CIP-014-3/CIP-006 and the ISPS Code, 33 CFR Part 105 and MTSA.

Unmanned and remote sites in homeland security and critical facilities use the same distance tracking as their first line of defense; see how perimeter intrusion detection compares to a fixed sensor, and why the false alarm rate matters more than raw sensitivity.

What is Intrusion Detection

Traditional motion sensors treat perimeter security as a pixel change problem: a moving leaf and a climbing intruder can trigger the same nuisance alarm. This system understands spatial depth, tracking how far a person is from the fence line and what they are doing at that distance. As someone approaches, a distance is tracked in real time. As they begin to climb, a fence violation alert fires, rather than waiting for them to already be over the top. Feeds run at 1080p to 4K, 15–30 fps, over existing RTSP or ONVIF Profile S/T streams from IP66/IK10 rated outdoor cameras, and the fence-line record can be retained on an operator-set 30–90 day window.

Key Takeaways

These are the core principles that define how Argu approaches every deployment. Our solutions are built to work on your existing infrastructure, require no engineering overhead, and deliver measurable results from day one. Every feature is designed with one goal: giving your team the intelligence to act faster, with more confidence, and without adding complexity.

How It Works

A camera covers the fence line

An existing perimeter camera, already mounted along the boundary, provides the video feed used for spatial detection. at 1080p–4K resolution over RTSP or ONVIF Profile S/T.

Depth and distance are tracked

The system tracks how far a person or object is from the fence line in three dimensions, not just whether a pixel has moved. at 15–30 frames per second.

Behavior at the boundary is assessed

As a person approaches, the system tracks whether they are walking past, standing still or beginning to climb, rather than flagging every movement the same way. against the same distance thresholds every time.

A fence violation alert fires

Once climbing begins, an alert is raised naming the location and the time, while the person is still at the fence rather than already inside. The event is retained on the operator's 30–90 day window.

Frequently Asked Questions

How is this different from a standard motion sensor for perimeter security?

A standard motion sensor reacts to pixel change and cannot tell a swaying branch from a person at the fence line. This system understands spatial depth and three dimensional boundaries, tracking how far someone is from the fence and what they are doing at that distance, so it flags a climb in progress rather than any movement nearby.

Does perimeter intrusion detection work at night?

Yes. Spatial depth perception is not dependent on daylight pixel contrast the way ordinary motion sensors are, so detection continues to work at night and in adverse weather such as rain or fog. Camera hardware rated IP66/IK10 and feeds at 1080p to 4K, 15–30 fps, support this in practice.

Will this reduce false alarms from wildlife or weather?

That is the intent of fence line monitoring built on spatial understanding rather than flat motion detection. Because the system tracks three dimensional boundaries and distance, ordinary movement near the fence is far less likely to be mistaken for a person climbing.

Do we need new cameras along the perimeter?

No. The system connects to RTSP streams, IP cameras and NVRs already installed along the fence line, adding spatial detection as a software layer rather than requiring new poles or cabling. Power and data can run over existing 802.3af/802.3at PoE, up to 100m over Cat6.

Can perimeter security data stay on site?

Yes. On premise deployment is available for sites that need fence line and perimeter data to stay local rather than sent to an outside cloud, a common requirement for government and critical infrastructure facilities that Argu already serves across four continents.

Does this help meet utility or port physical-security requirements?

It maps to the physical-security intent of NERC CIP-014-3 and CIP-006 at utility sites, and the ISPS Code, 33 CFR Part 105 and MTSA perimeter requirements at port and maritime facilities, though the operator remains responsible for the applicable compliance program.

How long is fence-line video retained?

Fence-line video plus the distance and behavior read can be retained together for a 30–90 day window set by the operator's own policy, and an on-premise deployment keeps that data on site.

Can AI video analytics detect loitering and unusual behavior near a perimeter?

A site can describe the behaviour it cares about in plain language, for example a person staying near a fence line, and Argu turns that sentence into a live agent in about thirty seconds. For climbing and approach it tracks distance and depth to the fence line, so a fence violation alert fires as someone starts to climb. It runs on the perimeter cameras already installed over RTSP or ONVIF Profile S/T at 1080p to 4K and 15 to 30 fps.
