Liverpool John Lennon Airport Modernises CCTV Management with Telent

Liverpool John Lennon Airport Modernises CCTV Management with Telent

Liverpool John Lennon Airport is undertaking a wider assessment of its surveillance infrastructure as technology specialist Telent works to improve the management and reliability of approximately 500 CCTV cameras across the airport estate.

The programme follows a successful trial of Telent’s Arbitex monitoring platform, which introduced automated camera checks to identify equipment faults and deteriorating image quality. Having subsequently begun a contracted rollout of the technology, the airport is now examining CCTV coverage, existing assets and opportunities to bring surveillance management together under a more integrated approach.

The work comes as Liverpool John Lennon Airport continues to expand its operations, having handled more than 5.6 million passengers in 2025, an increase of 11% on the previous year. Maintaining dependable surveillance across a busy airport involves a combination of equipment monitoring, physical maintenance and regular assessment of whether cameras continue to provide the coverage required.

Briefing

• Telent is assessing approximately 500 CCTV cameras at Liverpool John Lennon Airport.
• The programme follows a three-month trial of Telent’s Arbitex automated monitoring technology.
• Arbitex performs daily checks on camera connectivity, alignment and image quality.
• A contracted rollout of the monitoring platform began in April 2026.
• The wider assessment will inform surveillance coverage, maintenance priorities and future infrastructure investment.

Automated CCTV Condition Monitoring

CCTV installations are an established part of airport security and operational management, but maintaining a large camera network presents challenges that are not always apparent from a control room display.

A camera can remain connected to the network while its effectiveness gradually deteriorates. Dirt accumulating on a lens, a change in alignment or an emerging focus problem may compromise the usefulness of its images without producing the obvious warning associated with complete equipment failure. Conventional inspections can identify these problems, although their effectiveness depends on how frequently equipment is checked and the resources available to maintenance teams.

Telent’s Arbitex monitoring platform addresses this through automated image benchmarking. The system captures images from individual cameras and compares them against established reference frames, using algorithms to identify changes in alignment, image quality and availability.

The software can detect signs of contamination or obstruction and flag cameras requiring further investigation. It does not necessarily establish the underlying cause of every problem, leaving engineers to determine whether cleaning, adjustment, repair or replacement is appropriate.

Arbitex supports conventional analogue installations alongside IP-based cameras, with deployment options covering on-premises infrastructure and cloud environments. This compatibility allows automated monitoring to be introduced across equipment from different generations without necessarily requiring wholesale replacement of functioning cameras.

The technology is primarily concerned with the condition and performance of surveillance equipment. It differs from video analytics applications designed to recognise people, vehicles or particular activities within recorded footage, concentrating instead on whether the cameras themselves remain operational and capable of delivering usable images.

From Trial to Operational Deployment

Liverpool John Lennon Airport completed a three-month Arbitex trial earlier in 2026, working with Telent and its existing on-site maintenance contractor to evaluate automated checks across the CCTV estate.

According to Telent’s account of the trial, the deployment involved configuring individual camera records, calibrating reference images and refining reporting parameters to reflect the airport’s operational requirements.

This preparation is an important part of automated image monitoring. Cameras installed in different locations may experience changing lighting conditions, environmental contamination or legitimate alterations to their field of view. Establishing suitable reference images and reporting tolerances helps distinguish genuine equipment deterioration from normal variations in the operating environment.

Following the trial, the airport moved into a contracted rollout of Arbitex beginning on 1 April 2026, with the monitoring approach intended to cover its wider camera estate. Telent has not confirmed that every camera has completed onboarding, although the programme establishes a basis for more systematic condition reporting as deployment progresses.

Michael Brown, Head of Technical Services at Liverpool John Lennon Airport, said the trial had demonstrated the benefits of introducing automation to CCTV monitoring and that the airport was continuing to work with Telent on the next stage of modernisation.

While the companies have not published quantified reductions in camera downtime, engineering callouts or maintenance expenditure, automated reporting can give technical teams an earlier indication of potential problems and help organise inspections around equipment condition rather than relying entirely on scheduled checks.

Assessing Coverage and Existing Assets

The latest programme announced by Telent extends beyond monitoring individual cameras. Engineers will undertake a comprehensive review of the airport’s surveillance infrastructure, examining camera information, system performance and coverage across key operational areas.

A reliable equipment inventory provides the foundation for this work, bringing together information about camera locations, technical specifications, maintenance history and current operational condition. These records can then be considered alongside surveillance requirements to determine where existing arrangements remain suitable and where improvements may be necessary.

Although Telent has not identified specific deficiencies at Liverpool, the assessment provides an opportunity to examine overlapping coverage, ageing equipment and locations where operational changes may have altered surveillance requirements. Equipment that remains serviceable can potentially be retained, while cameras approaching the end of their useful life or no longer providing suitable coverage can be considered for replacement or repositioning.

The approach also allows maintenance and investment decisions to be based on the actual condition of the installation. An older camera delivering reliable images may require little attention, whereas a more recent unit operating in an exposed location could need regular cleaning or adjustment.

Mike Harten, Director of Transport Comms Systems & Services at Telent, explained the company’s approach: “Our work with Liverpool John Lennon Airport is focused on helping the team make the most of its existing infrastructure while planning for future requirements. By bringing together better visibility of CCTV performance, proactive maintenance and a more integrated approach to management, we can help the airport improve efficiency and make informed decisions about future investment.”

Managing Surveillance Across a Growing Airport

Liverpool John Lennon Airport recorded its busiest year in 2025, surpassing its previous passenger record set in 2007. The increase in traffic has been accompanied by investment in passenger facilities, including upgraded security screening equipment, new food and beverage areas and an expanded airport lounge.

Changes to terminal layouts, passenger circulation and operational facilities can affect surveillance requirements even where the existing camera installation remains broadly serviceable. Coverage that was appropriate when equipment was first installed may need reviewing as buildings, access arrangements and passenger movements evolve.

The modernisation programme will examine opportunities to improve how authorised personnel access and manage CCTV information, potentially reducing the administrative burden associated with maintaining separate records and monitoring arrangements. Integrating equipment data can also make it easier to coordinate maintenance activities across different parts of the estate, although the practical benefits depend on the compatibility of existing systems and the responsibilities assigned to individual teams and contractors.

Information governance remains another consideration. The UK’s Information Commissioner’s Office provides guidance covering surveillance systems, including appropriate access controls, data security and the handling of personal information.

Automated camera condition monitoring does not remove these obligations. As airports integrate surveillance infrastructure with wider technology management systems, arrangements for accessing footage, protecting information and maintaining operational accountability must remain appropriate to the environment in which the equipment operates.

Infrastructure Investment and Maintenance Planning

For Telent, the Liverpool programme combines its Arbitex monitoring technology with the engineering services required to assess and maintain a complex surveillance installation. The company already works across critical UK transport infrastructure, including railways, highways and airports, where monitoring equipment is often distributed across extensive operational estates.

The principles behind the Liverpool project are applicable beyond aviation. CCTV networks installed along highways, within tunnels, at railway stations and across major transport interchanges face similar maintenance challenges, particularly where cameras are difficult to access or exposed to weather, vibration and contamination.

Automated checks can improve the information available to maintenance teams, but physical inspection and engineering judgement remain essential when determining whether equipment is correctly positioned, providing suitable coverage or approaching the end of its useful service life.

Liverpool’s wider modernisation work remains at the assessment stage. Telent has not disclosed the contract value, a timetable for completing the survey or a budget for subsequent equipment upgrades, and the extent of any further investment will depend on the findings.
