John Oliver, Senior Product Manager at HKC Security, looks at the evolution of security systems and how installers can evolve their capabilities at a level commensurate with the technologies they supply and support

Security systems for both domestic properties and commercial premises have evolved significantly in recent years, and intruder alarms are no longer standalone products designed to detect unwanted entry.

They are now becoming the hub of a wider security ecosystem, bringing together intrusion detection, video verification, access control, automation and remote management.

For professional installers that creates significant opportunities, but also a new set of challenges. The skills required to fit systems go well beyond traditional wiring and installation, while customers are becoming more demanding about connectivity, usability, resilience and cybersecurity.

What’s more, installers are competing with a growing range of DIY and subscription-based security products that can make professional systems appear more complicated or expensive.

So, what does the modern intruder alarm installer need to consider when fitting solutions, and how can they be future-proofed to last?

Connectivity changes

One of the most immediate challenges facing the industry is the termination of traditional analogue PSTN and ISDN lines in the UK.

With these technologies due to be switched off in January 2027, control panels still dependent on them will need to be upgraded if their signalling is to continue working.

This makes auditing existing installations increasingly important. Installers need to identify homes and sites that are dependent on legacy connectivity and plan upgrades according to risk, customer requirements and insurance requirements.

The change also highlights a broader issue that an alarm system is only as resilient as the communication path between the premises and the Alarm Receiving Centre (ARC).

As IP connectivity becomes the norm, installers need to think carefully about resilience. Dual-path signalling can provide an additional layer of protection, but the infrastructure supporting that connectivity also needs consideration.

Unlike traditional telephone lines, IP equipment such as routers and communications equipment may not continue operating during a power failure without appropriate backup power.

So, for installers, connectivity is no longer simply a technical specification, it is an integral part of the security solution.

The skills gap is changing

The traditional skill set of a security installer is evolving, too, and although wiring and system configuration are still important, today’s installer needs an understanding of IP networking, cloud platforms and cybersecurity.

As alarm systems become connected and integrated with other technologies, the ability to install the hardware is only part of the job.

Specification is also becoming more complex, and installers may need to consider security grades, signalling performance, EN 50136 and DP levels, PD 6662, BS 8243, insurer requirements and the appropriate method of confirmation.

Getting these requirements right at the specification stage is critical, as checking an insurer’s requirements or police response criteria after a system has been quoted and installed can create unnecessary cost, disruption, and disappointment.

Therefore, the professional installer’s expertise has greater value than simply putting equipment on a wall, it is about understanding the risk, the standards and the complete system architecture.

False alarms are still a critical issue

For customers, technical complexity is not usually the priority, they just want a security system that works reliably, is easy to use and provides an appropriate response when something happens.

Nuisance and false activations remain a significant pain point, as they can undermine confidence in a system, and where a police response is involved, potentially affect whether that response is maintained.

There is also still some confusion around what it actually means for an alarm to be ‘monitored’ and what is required to achieve a police response.

This puts greater responsibility on installers to explain the complete journey, from detection and signalling through to verification, ARC procedures and the relevant response.

Good system design is also essential. The right detector needs to be selected and positioned for its environment, taking account of factors such as pets, drafts and wildlife.

User training is equally important, because a technically sophisticated system can still generate avoidable false alarms if users find it difficult to set and unset or do not understand how it operates.

From alarm system to security hub

Perhaps the most significant change is the role the intruder alarm itself is beginning to play. Rather than operating as a standalone system, the alarm can act as the central hub for a wider security solution, integrating access control, video verification, automation and smart-home or building-management functions.

This convergence is being accelerated by IP connectivity and cloud technology, while video and AI are opening up new approaches to alarm verification.

Video analytics can help distinguish between people, vehicles and other movement, while video verification and ARC video checks can provide greater context around an alarm event.

This can help filter false alarms and improve the quality of information available when a genuine incident occurs.

AI is also likely to play a growing role within the alarm itself, and rather than simply responding to a pre-defined event, systems can analyse patterns of behaviour and identify changes that may warrant attention.

For installers, this means the opportunity is moving beyond the initial installation. Cloud diagnostics, remote servicing and over-the-air updates can reduce unnecessary site visits, while creating opportunities for ongoing managed services and maintenance.

Cybersecurity as part of the specification

As security systems become more connected, cybersecurity can no longer be treated as someone else’s problem. The security of an alarm system depends not only on the installer but also on the manufacturer, software, cloud infrastructure and account management surrounding it.

Installers should be asking manufacturers about their approach to vulnerability management, software updates, support lifespans and account security.

Features such as multi-factor authentication and the elimination of default credentials are increasingly important considerations.

Regulation is also moving in this direction, and the EU Cyber Resilience Act is bringing greater cybersecurity obligations for manufacturers, including requirements around actively exploited vulnerabilities and severe incidents, with the main obligations applying from December 2027.

This means cybersecurity should be considered a product attribute in the same way as reliability, performance and functionality.

Futureproofing solutions

Another common mistake is specifying a system only for what a customer needs today. Sites evolve, businesses expand, users change and security requirements become more sophisticated.

A system that appears suitable at installation can quickly become restrictive if it lacks sufficient zone or user capacity or cannot integrate with other technologies.

Scalability and openness should be considered during specification, and installers should look at the system’s expansion capabilities and the availability of open APIs and integration options.

The same applies to the end of the installation’s life, and end users should understand who will maintain the system, how it is monitored and who owns the relevant data and app account.

These may not be the questions customers ask initially, but they can become extremely important later.

Despite the pressure from DIY and subscription-based products, the increasing complexity of security systems could actually strengthen the role of the professional installer.

The market is moving towards hybrid wired and wireless systems, greater convergence between intrusion and access control, increased use of verified alarms and more managed-service models.

These developments require expertise, and the installers best placed to take advantage of them will be those who invest in their own knowledge as well as the technology they install.

Training in IP networking, cybersecurity and relevant standards will become increasingly important, alongside maintaining recognised industry approvals.

There is also an opportunity to change the conversation with customers, and instead of competing purely on the initial installation price, installers can demonstrate the ongoing value of monitoring, remote maintenance, verification and cloud-based services.

The future of professional intruder alarm installation is not simply about installing better alarms, it is about delivering resilient, connected and intelligent security solutions that can adapt as the customer’s needs change.

So installers should audit legacy systems now, design for resilience, take false alarms seriously, understand cybersecurity, and choose technology that can evolve.
