- Own 24/7 Monitoring Centre
Monitored Intruder Alarm Systems in the UK
Vigilant provides certified intruder alarm monitoring for homes and businesses across the UK. Our own centre watches each alarm 24/7. It checks every signal. If it finds a real threat, our team acts at once.
Commercial Asset Protection Checks alarm signals, keeps links live, and alerts the right people.
Why Premises Need Monitored Intruder Alarms
Empty business sites can face break-ins at night. They can also suffer damage. Bells-only systems sound a siren at the site. But people nearby may ignore it. Owners may not know about a break-in. This can also upset insurers.
An intruder alarm monitoring service gives your site 24-hour cover. Staff do not need to check each alert alone. Instead, signals go to our own alarm receiving centre (ARC). Trained staff check them. They then work with keyholders and alarm response teams.
Commercial Intruder Alarm Systems for Business Premises
Commercial sites need strong security that fits their daily work. Sensors spot unwanted entry. The system sends secure signals. It can also link to other security tools.
- 01
Corporate Offices and Commercial Premises
Motion sensors, glass break detectors, and door or window contacts help guard offices. Systems can also link with access control that helps staff manage the site.
- 02
Industrial Units and Manufacturing Plants
Long-range passive infrared sensors guard loading bays, tool stores, and work yards. They can spot entry after work hours.
- 03
Logistics Hubs and Warehouses
Beam sensors and roller shutter contacts help guard warehouses and delivery sites. They can link with CCTV and remote monitoring. Staff can then check alerts.
- 04
Retail Stores and Commercial Outlets
Dual-technology detectors guard stockrooms and sales floors. They help cut false alarms. If someone breaks in, the system sends an alert.
- 05
Educational Facilities and Public Buildings
Zoned detection lets staff turn on alarms in chosen parts of a building. Other areas can stay open for daily use.
- 06
Residential Properties and Private Estates
Specialist domestic intruder alarm monitoring helps guard high-value homes. It can use hidden perimeter sensors and wireless panic devices.
Commercial Benefits of Intruder Alarm Installation
Professional intruder alarm installation helps guard your property. It can stop unwanted entry. It also sends checked alerts if someone gets past the outer doors or gates.

02 RAPID NOTIFICATION
Immediate Alert Escalation

Complete Perimeter Coverage
A site survey helps us place sensors in key spots. These may include doors, rear fire exits, and rooms with high-value stock.
- 07
Lone Worker and Staff Safety
Panic buttons and perimeter alarms can help keep staff safe. They can help during late shifts and when one person works alone.

- 03
Professional System Installation
Engineers fit the sensors and set up the main and backup links. They test each zone too. We aim to keep work at your site to a minimum.

Frequently Asked Questions About Monitored Intruder Alarms
Find answers about alarm checks, police response, alarm grades, and alerts.
What is a monitored intruder alarm?
A monitored intruder alarm links sensors at your site to our own centre. When the alarm goes off, it sends a signal by mobile or IP link. Staff check the alert. They then contact the right people.
What happens when my alarm is triggered?
When an alarm goes off, our team gets an encrypted alert. Staff check the signals. They call the named keyholders. If the rules are met, they contact the emergency services.
What grade of intruder alarm does my business need?
Your insurer's rules and the site survey help set the right grade. Many low-risk business sites need Grade 2. But sites with high-value goods may need Grade 3.
How do I get a police response for my alarm?
To get a police response in Britain, your alarm needs an official number from the local force. An approved firm must fit and check the system. The alarm must also confirm the threat.
Do insurers require NSI approved alarms?
This depends on your insurer's rules. Many insurers ask an approved firm to fit the alarm. This can help keep your property cover valid. It can also help if you make a claim after a loss.
