Our Alarm Receiving Centre Services

We provide a range of flexible ARC monitoring services tailored to your site security risks and monitoring requirements.

CCTV Monitoring


We oversee numerous commercial CCTV systems, both permanent and temporary, throughout the United Kingdom. In addition to serving as a conspicuous visual deterrent to discourage illicit activities, monitored CCTV enhances security by issuing audible warnings to potential intruders.

Furthermore, any disruptions can be remotely verified and promptly confirmed. Our CCTV monitoring services benefit from the backing of a skilled network of security personnel, prepared to intervene as necessary, and even proactively, to safeguard your business.

CCTV Monitoring

Fire Alarm Monitoring


In the year to December 2025, fire and rescue services in the UK responded to over 640,000 incidents, an increase of 6.8% on the previous year. Within those callouts, over 175,000 related to actual fires, increasing by 29%, and there were a tragic 266 fire-related fatalities recorded.

However, of all incidents attended, false alarms account for 39%, of which many occur when commercial buildings are unoccupied. To ensure proper notification of emergency services in the event of a fire, your commercial property must be equipped with fire alarm monitoring.

If your fire alarm system activates outside of business hours, without monitoring in place, who will be alerted? Clearway provides 24/7 fire alarm monitoring, ensuring that any false alarms are appropriately managed and that, in the event of a fire, emergency services are promptly contacted.

Fire Alarm Monitoring

Intruder Monitoring


Our advanced sensors enable immediate activation of your intruder alarm and a swift response from our team at the Alarm Receiving Centre, irrespective of the circumstances or the property’s remoteness, in the event of any unauthorised entry attempt.

Similar to our temporary CCTV solution, our wireless intruder detection systems seamlessly integrate with our Gold Standard accredited ARC.

This ensures that you can trust all alarms and alerts to be managed with the same high-quality security monitoring as our comprehensive, fixed CCTV services, providing you with peace of mind.

Intruder Detection

Alarm Monitoring Audit Trails


Many Clearway clients require alarm-monitoring services to protect vacant properties – these are extremely vulnerable targets without the right security protection in place.

24-hour ARC monitoring ensures that empty sites are continually monitored, and a rapid response is actioned should any attempted intrusions occur.

The Alarm Receiving Centre team provides real-time access to security monitoring, which means you have a complete audit trail that details and breaks down the sequence of events every time an alarm is activated or a call-out is required.

This process includes the provision of video and audio footage, time logs and details of liaison with the police and other emergency services.

Audit trails are also useful for managing your site, overseeing work progress and keeping a clear view of the premises even when you are not in attendance. Read more about our alarm monitoring services.

    Our Process

    Clearway NSI Gold accredited Alarm Receiving Centre

    How Our Alarm Receiving Centre Works in Action

    1. Alarm or CCTV System Is Activated

    When an alarm or CCTV camera is triggered, a secure signal is sent directly to our facility.

    2. Alert Is Logged

    Signals are received at our NSI Gold Cat II ARC and recorded by the assigned operator.

    3. Verification by a Trained Operator

    Qualified responders investigate the activation and determine the appropriate response.

    4. False Alarms Filtered Out

    Alarms found to be false are stood down to avoid unnecessary callouts or concern.

    5. Security Personnel or Emergency Services Contacted

    If a live incident is taking place, the responder will liaise with the appropriate teams or emergency services.

    6. Actions Recorded in an Audit Trail

    All alarms, responses and data are recorded with a full audit trail for insurance purposes, compliance or investigation.

    Key Problems Professional Alarm Monitoring Can Solve


    Clearway has over 20 years of experience at the forefront of the sector and regularly invests in our systems to leverage the latest technologies and newest advancements. We can assist with a wide range of challenges, including the following.

    1. You Aren’t Able to Respond to Alarms Outside of Working Hours


    Without monitored alarms, security incidents may go unnoticed until significant damage has already been done. ARC monitoring ensures every verified activation receives an immediate professional response.

    2. False Alarms Are Causing Increasing Costs and Time Wastage


    Repeated false callouts disrupt operations and increase costs. Our trained operators verify alarms before escalating incidents, ensuring responses are proportionate.

    3. You’re Trying to Manage Security Over Multiple Sites


    Managing security across several properties can leave gaps in oversight. Centralised monitoring enables every location to be supervised by a single accredited monitoring centre.

    4. Your Insurance Provider Requires Monitored Alarms to Offer Coverage


    Many insurers require professionally monitored alarm systems. ARC monitoring helps demonstrate compliance while reducing the financial impact of security incidents.

    5. Your Vacant Property Is Vulnerable to Criminal Activity


    Vacant buildings typically become attractive targets for criminals. Continuous monitoring ensures attempted break-ins are identified and managed immediately.

    6. You Need Clear, Verifiable Audit Trails of Alarm Responses


    Every alarm, response and action is recorded, providing evidence for investigations, insurance claims and compliance.

    What Do Our Alarm Monitoring Experts Say?

    ‘Effective alarm monitoring isn’t simply about receiving an alert—it’s about making the right decision within seconds.

    By verifying every activation, following agreed response procedures and coordinating the appropriate action, an Alarm Receiving Centre helps prevent security incidents from escalating while giving businesses complete confidence that their premises are protected around the clock.’

    A Successful Project: Remote Monitoring Captures Theft From Van

    Operators at the alarm receiving centre were able to review recorded footage from the tower and observed a van parking further up the road from the compound. A male in high viz vest and hard hat was seen to enter the site and approach the side door of the van the equipment was stolen from.

    He opened the door, removed an item of machinery and walked off site with the stolen item and drove away. Our recorded footage established exactly when, where and who committed the crime. The footage was downloaded and provided to the police.

    Frequently Asked Questions

    What Does ARC Mean in Security Terms?


    ARC stands for Alarm Receiving Centre, a central facility managed by trained responders who detect alerts, respond to alarm signals and investigate the cause of an activation or distress signal.

    Clearway’s ARC operates 24/7, 365 days a year, providing always-on assurance that if an alarm detects movement, activity triggers a CCTV surveillance system, or a colleague uses a lone worker alarm device, a professional response will be deployed.

    One of the key advantages, alongside a robust security response solution, is the ability to avoid false alarm callouts and identify when an alarm or alert does not require a keyholder to attend the premises. Common examples include wildlife, often setting alarms off during the early hours of the morning.

    What Is an Alarm Receiving Centre?


    An Alarm Receiving Centre acts as the hub where all data, alarms, and signals are monitored, reviewed, and logged by handlers in accordance with the client’s protocols. For example, a high-risk site may instruct responders to liaise immediately with on-site security teams when any alarm or sensor is triggered, for any reason, to allow for a rapid response.

    Alarm Receiving Centres manage all incoming alerts and can also monitor CCTV surveillance or AI-enabled security systems to alert the emergency services, communicate with personnel, or dispatch a security response team as appropriate.

    Our Alarm Receiving Centre is purpose-built and equipped with advanced monitoring and communications infrastructure and equipment, managing alerts ranging from security and intruder systems and alarms to business fire alarms and other elements of a risk management solution.

    How Does an Alarm Receiving Centre Work?


    When a security system, alarm, camera, or device is first installed, whether temporary or long-term, the signal is tested and verified, with secure transmission to ensure that communications or alarm signals cannot be intercepted or interrupted.

    This testing requirement ensures that when any piece of equipment transmits an alert, it is directed to the appropriate response team within the Alarm Receiving Centre, who will:

    • Log the alert or alarm signal.
    • Evaluate the cause.
    • Filter out false alarms.
    • Liaise with security teams, emergency services or other personnel.

    Monitored alarms help prevent a common scenario in which an alarm is activated, but no one is aware of it or responds to the alert until a break-in, security breach, or intrusion has already occurred. In contrast, an Alarm Receiving Centre is actively poised to react to any alarm signal.

    Responders can also evaluate the reason for an alarm by reviewing CCTV footage, body-worn safety cameras or alarm-activated cameras, which capture a snippet of live footage for assessment.

    What Is BS5979?


    BS is the abbreviation for British Standards, and BS5979 is the UK standard for remote centres that receive signals from security or fire safety systems.

    Holding the BS5979 quality mark demonstrates adherence to the highest standards related to alarm monitoring, including:

    • Alarm Receiving Centre management.
    • Facilities, planning and construction.
    • Centre operational standards.
    • Signal security and response protocols.

    To apply for BS5979, an Alarm Receiving Centre must be continually staffed, assuring clients of an around-the-clock monitoring service, with evidence of robust risk assessment processes. Other requirements include high-security locking systems and data protection.

    Clearway’s Alarm Receiving Centre is equipped with extensive infrastructure to ensure a flawless, reliable and professional response service, including military-grade security assets, emergency power generators, data back-up and replication facilities and an uninterruptible power supply.

    We are proud to uphold the highest quality standards in alarm monitoring, ensuring that our Alarm Receiving Centre is accessible only to accredited, trained personnel and that all data captured, stored, or transmitted is secure.

    Note that BS5979 remains applicable to established monitoring centres that already meet the required certification standards. However, BS8591 is also used to set codes of practice for remote centres managing alarm system signals.

    What Can Be Monitored?


    Clearways’ accredited Alarm Receiving Centre can monitor a wide variety of alarms, security, surveillance, safety and detection devices, including but not limited to:

    • Fire safety systems
    • CCTV monitoring
    • Security alarms
    • Vacant property alarms
    • Panic alarms
    • Emergency SOS calls
    • Keyholding signals
    • Personal attack alarms
    • Environmental alarms

    Each alarm signal is screened according to the policies and protocols in place, logging the alarm and actions taken, retaining comprehensive records of the response, and ensuring that relevant footage, infrared captures, and photos are safely stored for reference, investigation, and to assist in intruder apprehension.

    Businesses, landowners and public sector bodies can combine alarm and systems monitoring throughout their safety and risk prevention solutions, with coverage of all security assets or equipment provided by a highly qualified team of experienced alarm responders.
