Our bespoke, all-in-one commercial intruder alarm system is designed to keep your business safe and help you stay in complete control of your business’ security. 

Comprising a series of sensors connected to a control panel, the system sends alerts directly to your smartphone to notify you when it has been activated, armed or disarmed.

What you get with SECOM’s
Intruder Alarm System

24/7 Protection

Our intruder alarms are designed to offer you maximum protection whenever you need it. With a range of bespoke features to suit your needs, and our advanced analytics – you can rest easy knowing that your staff, property and valuable assets are being monitored.

Sensors That Do More Than Protect

Our wired and wireless business intruder alarm systems do more than alert you to dangers — they enable you to fix maintenance issues before they escalate. Sensors can be installed to measure doors opening or closing, temperature changes, and humidity levels. They can even be installed on pipes to detect leaks.

The commercial intruder alarm system can also pick up on other security risks, such as windows or doors that have been left open. We have a wide range of wired and wireless PIR sensors and door contacts to fit your business and fulfil your detection needs.

Manage Security On The Go With The App

Want to add or remove an employee’s access rights, review alerts or change door codes? All you need is our integrated SECOM app.

Our commercial intruder alarms allow you to remotely control and manage your security without having to contact us.

You can also remotely arm/disarm, and receive all alerts regarding the opening and closing of your business. The system also sends out activity/inactivity alerts to let you monitor areas that should typically be staffed, such as tills or changing areas.

Accessing Your Alert Log

Our commercial intruder alarm system comes with the ability to view alerts online, so you can receive a notification on the other side of the world in real-time. You also have access to previous alerts, which you can compare and review to identify any patterns or recurring problems across any of your sites.

Alarm Receiving Centres

Your commercial intruder alarm system will be connected to our state-of-the-art Alarm Receiving Centre (ARC), which is manned 24/7 by SECOM security experts. They monitor your alarms and react with utmost priority when an intruder has breached your premises, or if alarms are activated.

If your alarm is activated, we have different response types available to suit your needs:

  • Keyholder Only: You will be notified of an alarm activation via the SECOM app, and you will receive a call from our monitoring team.
  • Key Response Service & Police Response: If you do not answer after being informed of an alarm activation at your business, the police will be alerted and a professional keyholder will be dispatched to your site to investigate the alarm and secure the premises.
  • Keyholder & Police Response: If you do not answer after being informed of an alarm activation at your business, we will alert the police.
  • Guard Patrol Response: Once your alarm has been activated and received by the ARC, a fully vetted security professional is sent to your premises to conduct a thorough external check. They will not enter the property, and will immediately notify the police and wait for them if there are signs of a break-in.

More than just security

SECOM’s intruder alarms empower you to better manage health and safety compliance, and even find opportunities to reduce costs. Our commercial intruder alarm systems are designed to go above and beyond your basic security needs. By integrating them with other SECOM products, such as our monitored CCTV cameras, we can provide you with a truly comprehensive solution that meets all your business requirements.

Our suite of commercial intruder alarms can be connected to existing Building Management Systems, allowing you to save energy too. The commercial intruder alarm system is configured so that lights, heating and air conditioning can be switched on and off depending on whether the building is occupied.


Highly sensitive sensors can be placed on the ground level to detect water, and specialised water valves can detect when water is flowing and be turned off to prevent damage, if needed.

  • Install sensors to detect flooding and specialised water valves to turn water supply off in emergencies.
  • Receive notifications on your phone as soon as the sensors or valves detect water, allowing you to respond quickly.
  • Save time and money by dealing with problems as they occur, and not after it causes significant damage.


Most business premises require heating at some point of the year for employees, so it’s important to measure temperature to maintain stability and reduce waste.

  • Temperature sensors can alert you to cold or hot spots, allowing you to intervene in real-time.
  • Alerts for a sudden change in temperature or humidity may suggest a more serious problem which you can prevent early.
  • Essential for businesses that store temperature-sensitive goods to prevent degradation or spoiling.

Combine Products

Sensors provide important data, but they don’t give you eyes on the situation or give you additional information needed to make a decision.

  • When you receive an intruder alarm alert, check the nearest camera to assess the threat.
  • React quickly to alerts for temperature changes and burst pipes to prevent bigger costs.
  • Take advantage of the various human metrics CCTV cameras can record, such as heat mapping or occupancy to find new insights.

Your integrated business
security solution

Our suite of security solutions functions effectively across a diverse range of businesses, regardless of industry or size. Multi-site owners can rest assured knowing they will receive real-time alerts for all kinds of abnormal activity across every single site. Whether you’re getting one notification a week for an abnormal door opening at your single site, or multiple notifications a day from numerous locations, we can build you a bespoke, tailored commercial intruder alarm system to keep your business safe.

Integrating CCTV and access control solutions with your intruder alarm creates a comprehensive security solution that works more effectively and efficiently, allowing you to focus on growing your business. When one system is activated, the others can be used to verify. For example, the repeated opening of a window that must be kept shut can be checked against CCTV footage to find the root of the problem, so you can rectify it. Combine multiple solutions to create a bespoke package that works for your business.

Why does a business need a bespoke commercial intruder alarm system?

The cost of break-ins is felt keenly across the UK, and especially so due to the low prosecution rates. According to the British Retail Consortium’s 2022 data, 96 out of every 100 victims were potentially failed by the police and justice system. The security of your business is in your hands, so it is essential that you equip yourself with a commercial intruder alarm system that is designed to cope with the needs of a business.

The intruder alarm system must be bespoke because every business is different. By designing your intruder alarm system around your business, you can rest easy knowing there are no blind spots. SECOM meticulously surveys your business to understand where the risks are, and how to mitigate those risks with our suite of intruder alarms. Whether you need a simple office alarm system or something more extensive to cover multiple locations, we have you covered.

We’ve been in business for over 60 years, work with 15,000 customers, and have over 40,000 active contracts across the UK. We’ve continually honed our understanding of security and the measures businesses need to take to be safe. We don’t rely on our history and track record, we’re always looking to learn and contribute to the industry.

That’s why we are a Gold member of the National Security Inspectorate (NSI). This gives us the ability to link the wireless intruder alarm systems to an ARC for monitoring. Our NSI membership means that if your intruder alarm system is activated, we’ll contact the authorities.

Can SECOM monitor the safety of my business in real-time?

Yes. No matter what day or time of day, if any of your alarms are triggered, we will react as fast as possible. How we react depends on the nature of the issue and the type of system response you have, but we are always ready to contact the authorities and begin an immediate response.
