See What Cameras Cannot.
Detect intruders in zero visibility -- fog, dust, snow, or total darkness. Radar triggers your PTZ cameras to zoom and track the target automatically. This is the perimeter technology no camera-only system can match, and no competitor offers.
Your perimeter is long, exposed, and vulnerable around the clock.
The Problem: Cameras work in daylight and clear weather -- but what about the other 14 hours? Fog rolls in. Dust storms reduce visibility to feet. Snow blankets the landscape. Night falls and your infrared cameras reach a few hundred feet at best. Intruders know this. They time their approach for the conditions that blind your cameras. With a property crime clearance rate of just 15.9% (FBI UCR, 2024), the odds already favor the intruder -- and camera-only systems make the gap worse by going blind exactly when threats are highest.
Why Camera-Only Falls Short: Standard video surveillance detects what it can see. Thermal cameras extend range in darkness but are still defeated by heavy fog, blowing dust, and precipitation. Motion sensors generate excessive false alarms from wildlife, vegetation, and weather -- traditional alarm systems have 94-98% false alarm rates. Fence-mounted sensors detect perimeter contact but provide no advance warning. By the time the fence alarm triggers, the intruder is already at your boundary. None of these technologies detect a person approaching across open ground at long range in zero visibility.
The RadiusVision Approach
RadiusVision's radar-based intrusion detection uses Axis ground surveillance radar to detect, classify, and track moving targets regardless of lighting, weather, or atmospheric conditions. The Axis Radar provides 180-degree coverage, detecting people at 200 feet (60m) and vehicles at 280 feet (85m). AI-powered classification distinguishes people, vehicles, and animals to dramatically reduce false alarms. And here is the capability that changes everything: slew-to-cue. When radar detects an intruder, it automatically commands the nearest PTZ camera to lock on and track the target -- giving your monitoring team verified video of an approaching threat before they reach the perimeter. Complete managed security available with 24/7 monitoring and ongoing support.

Features
Detect Through Zero Visibility
Radar penetrates fog, dust, smoke, snow, rain, and total darkness. Your perimeter protection does not degrade when conditions change -- it remains constant, 24/7/365. Detect people at 200 feet, vehicles at 280 feet with the Axis Radar unit.
Slew-to-Cue PTZ Automation
When radar detects a target, it sends coordinates to your PTZ cameras, which automatically rotate, zoom, and lock onto the target for visual verification. Detection to visual confirmation in seconds -- no manual camera operation required.
Target Classification
Distinguish humans from vehicles from animals. Advanced signal processing classifies targets by size, speed, and movement pattern. False alarms from wildlife and environmental motion drop to near zero.
Wide-Area Coverage Per Device
A single radar unit covers a 180-degree detection zone that would require dozens of cameras to monitor. Protect your perimeter with fewer devices, less infrastructure, and lower cost per linear foot.
Verified Alarm Response
Radar detection plus automatic camera verification equals verified alarms with visual evidence. Dispatch law enforcement with confirmed intrusion data, not guesswork. Verified alarms receive priority police response.
Works in Every Condition
No degradation in fog, rain, snow, dust, smoke, or total darkness. Radar operates on microwave returns, not visible light. Your security does not take weather days.
Radar-Camera Integration
Radar Scans the Perimeter
Axis radar continuously scans a 180-degree field of view, detecting people at 200 feet and vehicles at 280 feet. Works through rain, fog, snow, and total darkness. The radar operates 24/7/365 without pause.
Classify and Filter
AI algorithms classify each detection — person, vehicle, animal, or environmental. False positives from wind, rain, or wildlife are filtered automatically. Only real threats generate alerts.
Slew-to-Cue Camera Verification
When radar detects a confirmed target, it sends GPS coordinates to the nearest PTZ camera, which automatically slews to track the intruder and captures verification footage. No operator intervention needed.
Alert, Respond, Document
Verified intrusions trigger immediate action — central monitoring dispatch, on-site audio warnings, or direct client notification. Every event is time-stamped and documented for evidentiary use.

Use Cases
Critical Infrastructure Perimeters
Power substations, water treatment plants, and communication facilities. Radar detects intruders approaching long before they reach the fence, in any weather, day or night. Copper theft at substations costs U.S. utilities an estimated $1 billion annually.
Oil and Gas Facilities
Refineries, compressor stations, and pipeline corridors face sabotage, theft, and environmental compliance threats. Radar provides early warning across vast perimeters where camera coverage alone leaves gaps.
Mining Operations
Open-pit mines, haul roads, and processing facilities in dusty, remote environments -- exactly the conditions where cameras fail and radar excels.
Power Substations
Copper theft at electrical substations causes widespread outages and billions in damages. Radar detects approach at long range, triggering camera verification and law enforcement dispatch before the fence is breached.
Perimeter Detection Solutions
Radar is the foundation of RadiusVision's perimeter detection capability -- combining detection, automatic camera verification, and verified alarm dispatch into one integrated system.
We design, engineer, and assemble complete surveillance systems in-house — not resold off-the-shelf cameras on a pole. Every system is built for the specific conditions it will face.
