Intruder Monitoring FAQs

Intruder Monitoring involves the 24/7 surveillance of intruder detection systems – such as motion sensors, door contacts, and glass-break detectors – by a professional remote monitoring centre. When a sensor is triggered, an alert is sent to Corps Monitoring’s ARC, where trained operators verify the threat and take immediate action. This transforms passive alarm systems into a dynamic, managed service capable of stopping intrusions before loss or damage occurs.

Once a sensor is activated, the system sends a signal to our ARC. Operators assess the situation using live CCTV feeds (if available), check system logs, and follow a pre-agreed escalation procedure. If unauthorised access is confirmed, they can contact emergency services, dispatch a response unit, or alert keyholders. In some cases, live audio warnings can be issued through on-site PA systems, deterring the intruder before they enter the premises. Events are logged in real time, and full reports are provided after each incident.

Intruder Monitoring can include:

• Passive Infrared (PIR) motion sensors
• Door and window contact sensors
• Glass-break detectors
• Vibration and acoustic sensors
• Shock sensors
• Pressure mats

These devices create an invisible net of security across your premises, particularly outside normal operating hours. For high-risk areas such as server rooms, cash offices, or restricted access zones, additional layered detection may be added for enhanced sensitivity.

Yes. One of the key benefits of a monitored intruder system is the ability to verify alarms before escalating. By combining sensor alerts with live CCTV footage, operators can determine if a real intrusion is occurring. This reduces unnecessary callouts and avoids wasting police time. Many insurance companies favour monitored systems for this reason, especially in commercial settings with high false alarm rates.

If a genuine threat is detected, Corps Monitoring operators follow a strict escalation protocol. This may include:

• Issuing a live audio challenge via on-site PA systems
• Notifying keyholders or designated staff
• Contacting police or emergency services
• Coordinating with mobile response teams
• Locking access points (if integrated with access control)

Each situation is dealt with calmly and professionally, ensuring the fastest possible response with minimal disruption. All actions are logged and reported to the client after the event, including timestamps, operator notes, and outcomes.

Yes. Intruder Monitoring is scalable and flexible, making it suitable for:

• Small offices and independent retailers
• Warehouses and logistics depots
• Multi-site businesses with centralised control
• Educational and healthcare campuses
• Construction and temporary sites

Whether you operate from one location or across a national estate, Corps Monitoring can build a solution that fits your risk profile and budget. Temporary systems are also available for short-term security requirements such as refurbishments or seasonal operations.

Insurers increasingly require that high-risk sites have professionally monitored intruder systems in place. Corps Monitoring’s NSI Gold status, combined with accurate alarm logs and verified incident response, helps clients meet their insurance obligations and may reduce premiums. Our audit-ready reporting ensures you can demonstrate due diligence and an active approach to risk management.

Absolutely. Intruder Monitoring works seamlessly with:

• CCTV Monitoring
• Fire Alarm Monitoring
• Lone Worker Monitoring
• Access Control
• Corps Protect Personal Protection Services

Integrated monitoring ensures that all aspects of your site’s safety are covered and allows for coordinated response. When systems are connected, one event – such as a forced door entry – can trigger multiple actions, including camera recording, alarm activation, and automatic notification to response teams.

Yes. All alarm data, recordings, and communication logs are securely stored and handled in accordance with GDPR and UK data protection legislation. Only authorised staff can access sensitive data, and detailed records are maintained for compliance audits. Corps Monitoring ensures that your privacy obligations are met while maintaining rigorous incident accountability.

Getting started is simple. Corps Monitoring conducts a site survey, connects your existing intruder system to our ARC, and agrees on escalation procedures with your team. We test all integrations and ensure alarm communications are functioning correctly. Once live, your premises are monitored 24/7 by security professionals trained to act swiftly and effectively. Ongoing support, maintenance, and service reviews are also included as standard.
