Perimeter Breach Detection
Monitor fence lines, boundaries, and site perimeters with AI that detects intrusion attempts, climbing behaviour, and boundary violations across your entire estate.
How It Works
Under the hood
Perimeter security works differently from interior monitoring. The system analyses movement patterns at and around boundary lines, looking for the specific behaviours associated with intrusion attempts. This includes climbing motion on fences, cutting or pulling at barrier materials, crawling under gaps, and the approach patterns that precede forced entry.
The model distinguishes between legitimate boundary activity (maintenance workers at the fence, deliveries at the gate) and intrusion behaviour. Time of day, direction of approach, and movement speed all factor into the risk assessment. Someone walking alongside a fence during the day scores differently from someone approaching the same fence at 3am from an open field.
For large perimeters, the system tiles across multiple cameras and creates a unified boundary model. An individual detected moving along the perimeter by one camera is tracked as they enter adjacent camera zones, building a complete picture of their approach path and intent before they reach any access point.
Why It Matters
The real-world impact
Physical perimeter security is expensive and imperfect. Fences can be climbed. Barriers can be cut. Patrols can only cover a fraction of a large boundary at any given time. Most perimeter breaches on large sites go undetected until long after the intruder has entered.
Archangel turns every perimeter camera into an active sensor that never takes a break. The system provides the same level of awareness as a continuous human patrol but at a fraction of the cost and with perfect consistency. For sites with high-value assets, sensitive materials, or duty-of-care obligations, it's the most cost-effective way to maintain genuine perimeter security.

Capabilities
What it detects
Purpose-built detection models tuned for real-world conditions and operational environments.
Climbing & Scaling Detection
Recognises the motion patterns of climbing, vaulting, and scaling across fences, walls, and barriers in any lighting conditions.
Approach Path Tracking
Monitors the area around your perimeter, tracking approach vectors and identifying suspicious movement patterns before contact with the boundary.
Multi-Camera Stitching
Links adjacent camera feeds to track an individual moving along the perimeter, building a complete movement trail across your entire boundary.
Night and Low-Light Performance
Optimised for the lighting conditions that perimeters face at night. Works with infrared cameras, low-lux sensors, and mixed lighting scenarios.
