I. System Positioning
Perimeter Protection System is the outer "first line of defense" and "invisible fence" of the security system. Its core mission is tosecure the perimeter boundaries and intercept climbing intrusions— By deploying electronic fencing, infrared beams, and other detection devices along the perimeter walls of parks, residential communities, and factory sites, the system achieves real-time detection and automatic alarm for illegal climbing, scaling, and wire cutting. The system upgrades traditional "wall-based human interception" to "smart early warning and proactive interception," forming a three-dimensional defense of "alarm at the perimeter, evidence on camera" through linkage with video surveillance — serving as the "moat" of park security management.
II. Equipment Composition and Functions
| Equipment | Core Function | Selection Key Points |
|---|---|---|
| Electronic Fence | Pulsed high-voltage electronic fence, combining detection and deterrence | High-voltage pulse host + alloy wires; triggers alarm upon contact and delivers a deterrent shock (safe current, non-injurious); selected by perimeter length, supports 4/8 zone division |
| Infrared Beam Detector | Infrared beam detection, triggers when crossed or climbed over | Opposed infrared detectors (2/4/8 beams), detection range selected by perimeter length (30-250 meters); waterproof and anti-fog design, rapid alarm response |
| Pulsed Power Grid | High-voltage pulsed power grid, strong deterrence + precise alarm | High-voltage pulse grid host + galvanized steel wires; detects short circuit / open circuit / contact triple alarms, mainly for high-security perimeter walls |
III. Core Functions
Intrusion Climbing Alarm— When someone attempts to climb or scale the perimeter wall, the electronic fence triggers an alarm upon contact, and infrared beams trigger when obstructed. The system sends alarm signals within seconds, achieving "instant alarm on climbing, immediate notification on crossing"
Multi-tier Defense System— Electronic fence (contact detection + deterrent shock), infrared beams (beam interception), and pulsed power grid (strong deterrence) can be deployed in combination, forming multi-layer protection of "line - surface - grid"; supports zone division by wall segments, with alarms precisely located to specific sections
Alarm Linkage and Response— Upon alarm trigger, on-site sirens and strobe lights activate, and alarm information is simultaneously pushed to the monitoring center and mobile APP; automatically links with video surveillance to retrieve footage of the corresponding zone, allowing security personnel to remotely verify the scene and respond quickly, forming a closed loop of "alarm — linkage — response"
All-weather Stable Protection— The system features anti-cutting, anti-short-circuit, and anti-tamper alarm functions; deliberate equipment damage also triggers alarms; adapts to harsh conditions such as rain, snow, fog, and nighttime, operating 24/7 to ensure gap-free perimeter security
IV. Solution Advantages (Based on Yunzhi Company's Practice)
Leveraging its weak-current intelligent system integration capabilities, Yunzhi Company provides unified integration of perimeter protection systems with video surveillance, intrusion alarm, and electronic patrol systems, achieving three-dimensional protection of "perimeter alarm + video linkage + patrol verification." These solutions have been deployed in park, residential community, and factory projects, helping clients build a collaborative "human defense + technical defense" outer security barrier.
