Video alarm verification: the complete guide to securing your business

When a security alarm is triggered, determining whether there is a genuine threat is essential. False alarms, caused by anything from environmental factors to human error or technical faults, can result in unnecessary disruption, wasted resources and potentially affect police response arrangements.

Video alarm verification provides an additional layer of security by enabling trained monitoring operators to visually assess an incident when an alarm is activated. By reviewing images from connected CCTV cameras, operators can establish whether there is evidence of suspicious activity and determine the appropriate response.

At Scutum, we understand the importance of reliable, responsive security. By combining advanced video technology with professional alarm monitoring, we help businesses reduce unnecessary callouts, improve incident management and make more informed security decisions.

What is Video Alarm Verification?

Video alarm verification is the process of using CCTV footage or images to visually assess an alarm activation and help establish whether a genuine security incident is taking place.

When an alarm is triggered, images from connected cameras can be reviewed by trained operators at an Alarm Receiving Centre (ARC). This enables them to assess the situation, identify potential threats and initiate the appropriate response in accordance with agreed procedures.

Video verification is the process by which an alarm monitoring operator views the images from a site’s cameras at the moment an alarm is triggered, in order to establish its real cause.

It differs from two set-ups it is often confused with:

Video alarm verification adds an important layer of security by enabling trained operators to visually assess an alarm activation and distinguish between potential security threats and false alarms. This additional information supports faster, more informed decisions and helps determine the appropriate response, whether that involves contacting keyholders, deploying security personnel or requesting police assistance where applicable.

Video verification services are typically managed through Alarm Receiving Centres (ARCs), which operate in accordance with recognised industry standards. In the UK, BS EN 50518 sets out requirements for the construction, technical facilities and operation of monitoring and alarm receiving centres, helping to ensure that alarm signals are handled securely, reliably and effectively.

ARCs can be independently certificated against relevant standards by accredited certification bodies, such as the National Security Inspectorate (NSI) or SSAIB. This provides businesses with additional assurance that their chosen monitoring provider operates to recognised industry requirements.

Good to know: When selecting an alarm monitoring provider, ask which standards its Alarm Receiving Centre is certificated to and which independent certification body provides the certification. This can help you assess the quality, reliability and resilience of the monitoring service.

Not all alarm receiving centres are equal. Before signing a contract, always ask which standard the centre that will handle your alarms is certificated to, and by which certification body.

1. Alarm activation

When a security detector, such as a motion sensor, door contact or glass-break detector, identifies potential suspicious activity, it sends a signal to the site's alarm control panel. The alarm system then transmits the activation to the monitoring centre.

2. Receipt and initial assessment

The monitoring centre receives the alarm signal and, where the system is configured to allow it, operators can access footage from CCTV cameras covering the affected area. For example, if an alarm is activated at a warehouse loading bay, the operator can review images from cameras monitoring that location.

3. Visual verification

A trained operator reviews the available live or recorded footage to assess the cause of the activation. This may help distinguish between genuine suspicious activity, accidental activation, environmental factors or technical issues.

4. Decision and response

Based on the available evidence, the operator follows established response procedures:

• Confirmed security incident: The operator initiates the appropriate response, which may include notifying the designated keyholder, arranging security attendance or contacting the police where the relevant requirements are met.
• False alarm: Where the activation can be confidently identified as a false alarm, the incident is recorded and handled in accordance with agreed procedures, helping to minimise unnecessary callouts and disruption.
• Inconclusive activation: If the available footage does not establish the cause, the operator follows the agreed escalation procedures, which may include further checks or contacting a designated keyholder.

All actions and outcomes are recorded to provide an audit trail of the incident and the response taken.

Why it matters: Effective video alarm verification depends on more than speed alone. Camera quality, strategic positioning and reliable connectivity between the premises and the Alarm Receiving Centre (ARC) are all essential. Combined with the expertise of trained monitoring operators, these factors enable accurate assessments and support a timely, appropriate response to security incidents.

An unverified false alarm has a real cost for your business:

Verified calls are the ones the police can treat as a priority, because they rest on concrete visual evidence rather than on mere presumption. In England, Wales and Northern Ireland, a monitored system registered with the police under a Unique Reference Number (URN) qualifies for Level 1 response, the immediate level, subject to police demand and resources at the time. Providing evidence from the outset (an image of an individual on site, a description of their behaviour, their precise location in the building) speeds up mobilisation and operational decision-making for the teams who respond.

The images captured at the time of the incident are evidence that can be used directly:

• For your insurer, in the event of a loss or theft, to speed up settlement of the claim;
• When reporting the crime, by giving investigators precise material evidence;
• In legal proceedings, if the offenders identified are prosecuted..

Simply knowing that an active surveillance system is in place, with human verification in real time, discourages a significant share of intrusion attempts. An intruder knows that an alarm combined with video verification drastically reduces their chances of leaving without being identified.

Yes. In England, Wales and Northern Ireland, alarm confirmation is even a condition of police response to a newly installed intruder alarm. This stems from police policy rather than from statute. Under the National Police Chiefs’ Council (NPCC) requirements for response to security systems, a remotely monitored alarm system must conform to PD 6662 and BS 8243, the code of practice for systems designed to generate confirmed alarms, in order to be registered with the police under a Unique Reference Number (URN). Detection-activated CCTV must, for its part, be installed to BS 8418. False calls have a direct consequence: after three in a rolling 12-month period, police response is withdrawn. Police Scotland applies its own policy, with its own thresholds.

In practice, this means that your system and your monitoring provider must be able to deliver confirmed alarms, whether that confirmation is visual, audio or sequential.

This framework comes with strict requirements under the UK GDPR and the Data Protection Act 2018:

• Images are viewed only when an alarm is triggered, never freely or continuously;
• Only authorised, trained operators have access to the video feeds;
• Access is secured and logged, to guarantee confidentiality and the traceability of every viewing;
• Your employees must be informed that the system is in place where it films workspaces;
• The retention period for footage is governed by contract and by data protection law.

This scrupulous compliance with the legal framework and the UK GDPR is directly linked to the professionalism of the alarm receiving centre. This is precisely what independent certification of a centre attests: that it meets not only performance requirements, but also strict requirements on the physical security of the centre, the logging of events and the screening and vetting of the staff who handle your alarms.

Video verification turns an alarm, uncertain by nature, into a fast, reliable decision. For your business, it guarantees three things: fewer false alarms and associated costs, a faster and more effective response when an incident is real, and usable evidence in the event of a loss or legal proceedings.

It is not one more security expense: it is an investment in the continuity of your business. This is how video verification fits squarely within the promise Scutum makes to its customers: to deliver operational certainty, so your success is built to last, whatever the size or complexity of your sites.

Conventional alarm monitoring relies mainly on the information sent by intruder detectors (movement, opening, etc.). Video verification allows an operator to check visually what caused the alarm to trigger. It makes it possible to tell a genuine intrusion from a false activation (an animal, a handling error, a technical incident and so on). Responses by the police or a security officer are therefore triggered on the basis of more reliable visual evidence.

In most cases, yes: the cameras must be compatible with the monitoring system and allow secure access to the images. Some existing installations can be reused if they meet the technical requirements. A preliminary survey makes it possible to check whether the equipment already installed is compatible.

Professional systems often have a back-up path over the mobile network (4G/5G). The alarm generally continues to work even if internet access is lost. However, the transmission of images may be limited if no back-up connection is available. A loss of communication can itself raise an alert at the alarm receiving centre. A dual transmission path is recommended to guarantee continuity of service.

Images are viewed only when an alarm is triggered or in the situations provided for in the contract. Only authorised, trained operators have access to the video feeds. Access is secured and logged to guarantee confidentiality. The processing of images complies with the regulations in force, in particular the UK GDPR. Employees must be informed that the system is in place where it films workspaces. Cameras are installed in line with the applicable rules, to avoid any disproportionate intrusion into privacy.

The cost is generally higher than for an alarm alone, because it includes video surveillance and the involvement of qualified operators. The price depends on several factors: the number of cameras, the size of the site, the level of monitoring required and the options chosen. Video verification can reduce the costs linked to false alarms and unnecessary call-outs. For businesses, it is often a cost-effective investment thanks to more effective protection of assets and operations.

Video verification can reduce the volume of call-outs by mobile security officers by 15% to 20%.
