An integrated 32-zone intrusion detection upgrade for STMicroelectronics Loyang, ensuring 100% perimeter integrity through alarm-surveillance coordination.
STMicroelectronics' Loyang facility is a critical node in the global semiconductor supply chain. Protecting high-value fabrication equipment and intellectual property requires a perimeter strategy that is both highly sensitive to intrusion and resilient against environmental triggers. Securevision was engaged to overhaul the site's ageing perimeter detection system with a unified, verified alarm platform.
| Client | STMicroelectronics (Loyang Facility) |
|---|---|
| Location | 11 Loyang Lane, Singapore |
| Sector | Industrial - Electronics Manufacturing |
| Facility Type | High-Value Semiconductor Manufacturing Plant |
| Environment | Highly restricted zones, large perimeter fence line |
| Project Type | Perimeter Security Upgrade |
| Completion | October 2021 |
| Scale | 1.2km fence line, 32 zones, integrated RISCO alarm platform |
The primary challenge for the STMicroelectronics Loyang facility is its scale. With a 1.2km perimeter bordering industrial roads and adjacent foliage, the site is vulnerable to environmental false alarms. High winds, heavy rain, and local wildlife frequently triggered legacy PIR sensors, leading to "alarm fatigue" where genuine intrusions could be missed by a desensitised guard team.
In a high-value semiconductor environment, unverified alarms are a significant operational risk. Each alarm requires a manual patrol to verify the cause, diverting security resources and creating windows of vulnerability. The industrial reality of this site demanded a system that could not only detect an intrusion but immediately verify it visually for the control room.
Furthermore, the long-distance cabling required for a 1.2km perimeter necessitates industrial-grade network infrastructure that can deliver consistent power and data across the entire site without signal degradation in harsh weather.
| Security Dimension | Legacy State | Securevision Upgrade |
|---|---|---|
| Perimeter Detection | Unverified PIR sensors | 32-zone RISCO LightSYS platform |
| Alarm Verification | Manual exploratory patrol | Automatic PTZ preset triggering |
| Response Time | 3–5 minutes (manual) | Under 10 seconds (visual) |
| Infrastructure | Standard network switching | Ruijie industrial-grade PoE backbone |
The key engineering decision at Loyang was how to segment the 1.2km perimeter. A single large zone would be impossible to manage, as an alarm would not provide enough detail on where to look. Conversely, too many zones would overcomplicate the management platform.
Securevision designed a 32-zone logical architecture, with each zone corresponding to a specific camera field of view. We recommended an integrated RISCO-Hikvision bridge that allows the alarm panel to command PTZ cameras to instantly "slew-to-cue" upon a zone breach.
This approach transformed the security operation from a blind search to a directed response, significantly reducing the time-to-verification for the site's security team.
Our engineering team focused on building a perimeter that remains functional even in the event of partial hardware or network failure.
Divided the 1.2km fence line into manageable zones, allowing for precise incident location mapping in the control room.
Programmed PTZ cameras to automatically zoom into the triggered zone upon an alarm event, providing instant visual proof.
Deployed Ruijie Reyee industrial PoE switches to ensure consistent power delivery to cameras at the furthest points of the site.
Unified the RISCO alarm feeds with the VMS, providing a single dashboard for the guard team to manage the entire perimeter.
This layered approach ensures that the STMicroelectronics facility is protected by a system that is as resilient as the manufacturing processes it guards.
The final system provides an end-to-end detection and verification workflow that hardens the site against unauthorised access.

The slewing PTZ integration has ensured that every perimeter alarm is instantly verified before a patrol is dispatched.
Comprehensive 32-zone coverage has eliminated the security gaps and blind spots inherent in the legacy system.
By automating the verification process, the security team can focus on genuine incidents rather than exploratory patrols.
When securing a 1.2km perimeter, the enemy is not just the intruder-it is ambiguity. An unverified alarm at a remote corner of a semiconductor plant is a liability. By bridging the alarm panel and the surveillance platform into a "slew-to-cue" workflow, we remove the guesswork and provide the control room with instant, actionable visual evidence.
Every project Securevision delivers draws on multiple systems working together - cameras, access control, intercoms, vehicle management, network infrastructure, and platform software. The cards below show the full range of systems we design and install. Each one links to a deeper explanation of how it works, when it is needed, and what to look for when specifying it.
