With over 30 years of experience, we’re trusted across Nottinghamshire, Derbyshire, Leicestershire, and the wider UK for quality CCTV repair and maintenance services.

Why CCTV Servicing matters
CCTV has changed enormously over the last 10-15 years.
The industry has seen a shift from analogue CCTV and large camera form factors, to digital sealed-unit turret style cameras. Image quality and resolution has improved dramatically and systems are now more advanced with AI features and video analytics built into even entry level cameras.
This means our engineers need to be familiar with traditional cameras and servicing requirements, as well as digital networking. Fortunately, our directors all have computer science degrees and worked in the IT industry before joining the company. This positions us well to ensure our staff are trained accordingly for a changing industry.
Firmware updates are more important than ever to tackle hacking and malicious activity. Regular CCTV camera service helps prevent problems, reduce downtime, bring new features for your system, and ensure compatibility for years to come.
Some key benefits of a regular surveillance camera service include:
Some common issues you may encounter with your CCTV system include:
Cameras losing power or signal
Blurred or distorted images
Recording devices failing to store footage
Software or network problems
Damaged or weather-affected equipment
CCTV Repairs and System Upgrades
If your system develops a fault, our engineers provide fast and reliable CCTV system repair services.
Where possible, we repair faulty systems quickly on-site. If your system is outdated or beyond repair, we can recommend and install cost-effective upgrades to restore full protection. We can also provide CCTV repairs and maintenance for third-party systems, not just those we’ve installed.

Business CCTV Maintenance
A faulty or poorly maintained commercial CCTV system can leave gaps in coverage, compromise evidence, and even affect insurance compliance.
That’s why we offer tailored and flexible business CCTV maintenance packages designed to keep your system operating at peak performance all year round.
Our commercial CCTV maintenance services include:
- Scheduled inspections
- System testing
- Cleaning of lenses
- Full camera and recorder performance checks

If any issues are found, our engineers will provide prompt CCTV repairs or recommend suitable upgrades to restore full protection. With regular maintenance, you can be confident that your CCTV will provide reliable coverage, high-quality footage, and long-term return on investment.

Over 90% of CCTV systems are now internet connected. This is great for the end user as it allows us to offer even more value to our maintained customers.
Through platforms like Hikvision’s Hik-Partner Pro or Dahua’s DoLynk, we can request permission from our client to view live images, access their recording equipment, and offer help, advice, and support, often saving costly engineer visits. This is a service we provide as standard for all our maintained customers.
Asset Tracking
At Mercury Fire & Security, we’ve made significant investments in industry-leading asset tracking software to improve both customer experience and the efficiency of our operations.
This technology allows us to deliver clever reporting, smoother communication, and faster, more accurate servicing, ensuring every aspect of your systems is managed to the highest standard.
The two main reasons why we have done this are:
Customer experience:
We strive to offer our customers the best experience and appreciate the importance of clear reporting. We’ve put a lot of effort into our forms to ensure you focus on what’s important. For our large clients, customer portals help to manage service schedules and quotations for repairs and new work.
Efficiency:
We want our engineers to service all equipment on your site, to not only complete it quickly, but more importantly, complete it properly. By using site imagery, floor plans, asset lists, and photos, our engineers find your site and the appropriate equipment quickly. Our step-by-step maintenance forms guide our engineers through checks to ensure nothing is missed and to ensure standards are met.

This technology-driven approach allows us to combine speed, accuracy, and accountability, giving clients complete confidence that their assets are properly maintained and compliant at all times.

Floor Plans
By using floor plans, our engineers can quickly get to your equipment, saving time and money. Not only can engineers and office support staff see these plans, but with the customer portal, our maintained customers can quickly see where problems lie.

Our powerful forms show engineers what to check and when, as well as showing previous results from the last visit helping to spot trends and faults developing.
Reporting
To help our clients understand some of the jargon within the industry, our reports use powerful categorisation of defects, including:
- Critical Defect
- Non-Critical Defect
- Non-Conformance
- Recommendation
- Information
At a glance, our clients can see the importance of issues raised in a clear table. Links take customers to quotes that can be approved online with photos of the issues highlighted by engineers.
