Intruder Detection Systems

Detect and deter threats with reliable intruder alarm systems.
Intruder alarm systems are a vital first line of defence against unauthorised access, theft, and vandalism. At VWS, we design, install, and maintain tailored intruder detection solutions for commercial premises, care environments, housing associations, retail sites, and more.Whether wired, wireless, or hybrid, every system is specified to suit your building layout, risk profile, and day-to-day use. We ensure full compliance with British Standards and insurer requirements, delivering reliable detection through carefully selected sensors, control panels, sounders, and monitoring options. With robust installation, clear documentation, and ongoing support, we help safeguard your property — and your peace of mind.
Our service doesn’t stop at installation. We provide 24/7 reactive support, routine testing, and planned maintenance packages to keep your intruder systems performing reliably at all times.Integrated with our CAFM platform, every event, fault, and service visit is logged with photographic evidence and full compliance records. You’ll have real-time visibility of system status, outstanding issues, and completed works — without the need to chase updates. With VWS, intruder protection becomes a seamless, dependable part of your wider security strategy.

Detection & Sensors

The performance of an intruder system relies heavily on the quality, positioning, and configuration of its detection devices. We deploy a carefully selected mix of PIR motion sensors, door and window contacts, vibration and glass-break detectors, and beam systems to provide reliable coverage across vulnerable areas.Every device is chosen based on risk level, environmental conditions, and the need to minimise false alarms. Through intelligent zoning, sensitivity tuning, and precise installation and calibration, we ensure alerts are accurate and actionable — so your system responds only when it should.

Panel Control & Monitoring

The control panel is the central intelligence of your intruder system. VWS installs secure, intuitive panels that manage alarm zones, signalling, and response workflows with clarity and reliability.We provide both locally monitored solutions and systems connected to an Alarm Receiving Centre (ARC). Our panels can integrate seamlessly with CCTV, access control, and lighting systems, creating a unified approach to site security. To ensure continuous operation, we also specify backup power and tamper protection — keeping your system functional even during faults or power interruptions.

Remote Alerts & Automation

Modern intruder systems are significantly enhanced by remote monitoring and automation. We deliver solutions that provide real-time alerts and status updates via phone, SMS, or mobile apps, keeping you informed wherever you are.Automation features can include scheduled arming and disarming, geofencing, and integration with other building systems — such as triggering lighting or locking doors in response to an event. These capabilities strengthen security, reduce the risk of human error, and give you greater control when managing multiple sites or locations.

Maintenance & Response Services

Here’s a modernised version with a strong reliability and lifecycle focus:Ongoing performance is critical to effective intruder protection. Our maintenance packages include scheduled testing, sensor calibration, battery replacement, and on-site inspections, all recorded within our CAFM system with clear timelines and documentation.If a fault or alarm activation occurs, our reactive response team acts quickly to diagnose and resolve issues. By minimising downtime and maintaining compliance, we ensure your system remains ready — so when protection matters most, it’s there without fail.
