CCTV Repair, Maintenance
& System Upgrades
Across London
Cameras not recording? App stopped connecting? System outdated? We fix, maintain, and upgrade CCTV systems from any manufacturer. Same-week callouts, fixed pricing, and repairs guaranteed.
Your CCTV System Should Work When You Need It Most
A CCTV system that isn't recording is worse than no system at all — it gives you a false sense of security. You discover the problem when you actually need footage, and by then it's too late.
We repair and maintain CCTV systems from all manufacturers — Hikvision, Dahua, Swann, Samsung, Qvis, and others. Whether it's a single failed camera, a dead hard drive, a connectivity issue, or an entire system that needs replacing, we diagnose the problem and fix it with same-week callouts across London.
Every repair comes with a fixed quote before work begins. No hourly rates, no surprise charges, no parts markup. You know exactly what you're paying before we touch anything.
Already have a system installed by someone else? That's fine — we service and repair systems regardless of who installed them. Many of our maintenance clients came to us after their original installer stopped trading or became unresponsive.

Diagnose First, Fix Right
We don't guess — we diagnose. Every repair visit starts with a systematic check of your entire system: cameras, cables, connections, NVR, hard drive, and network. We identify the root cause before quoting a fix.
This approach means we fix the actual problem, not just the symptom. A camera showing intermittent black screens might be a cable issue, a power supply problem, or water ingress — the fix is completely different in each case.
When Repair Isn't Worth It
Sometimes repairing an old system costs more than it's worth. If your cameras are producing low-resolution footage, your DVR no longer receives firmware updates, or multiple components have failed, a full upgrade delivers better value.
Modern CCTV systems offer dramatically improved image quality, reliable remote viewing, AI-powered detection, and 60+ days of recording. Many upgrades reuse existing cable routes — keeping installation cost down while delivering a completely new system.
Transparent Repair & Maintenance Costs
We quote a fixed price before starting any work. You approve the cost, we complete the repair — no hourly rates creeping up, no parts marked up to 300%.
Repair costs depend on the fault. Simple fixes — network reconnection, settings reconfiguration, firmware updates — are at the lower end. Hardware replacements — cameras, hard drives, power supplies — cost more but include the replacement component.
Maintenance contracts provide the best value for ongoing reliability. A single annual visit catches problems before they cause footage loss, and priority callout response means faster attendance when urgent issues arise.
For systems beyond economical repair, we provide a free upgrade survey with a detailed specification and fixed quote for a complete new system.

From Fault to Fixed — Fast
When your CCTV stops working, every hour without footage is a risk. Our repair process is designed for speed without cutting corners — diagnose accurately, quote honestly, and fix permanently.
Most repairs are completed in a single visit. We carry common replacement parts — hard drives, power supplies, connectors, and popular camera models — so we can often fix the problem on the spot without a return visit.
For upgrades, we start with a free survey to assess your existing system, design the replacement, and provide a fixed-price quote. Installation is typically completed within a week of approval.
Step by Step
Describe the Problem
Call or message us with your CCTV issue. We'll ask targeted questions to narrow down the likely cause and schedule a same-week visit.
On-Site Diagnosis
Our engineer systematically tests your entire system — cameras, cables, NVR, hard drive, network, and power. We identify the root cause, not just the symptom.
Fixed Quote
Before touching anything, you receive a clear, fixed quote for the repair. You approve, we proceed. No approval, no charge for the diagnostic.
Repair & Test
We complete the repair, test every channel, verify recording, check remote access, and confirm night vision. The system is fully operational before we leave.
Guarantee Activation
Every repair is guaranteed — 6 months on repairs, 12 months on replacement components. If the same fault returns, we fix it at no cost.
Signs Your CCTV System Needs Upgrading
Not every problem needs a repair. Sometimes the most cost-effective solution is a modern replacement that delivers dramatically better performance and reliability.
Low Resolution Footage
If your cameras produce grainy, pixelated images where faces aren't identifiable at 5+ metres, they're too old. Modern 2K and 4K cameras capture clear facial detail at 15–20 metres.
Frequent Hard Drive Failures
NVR hard drives run 24/7 and last 3–5 years. If you're replacing drives regularly, the NVR itself may be causing premature failures. A new system is more reliable and cost-effective.
No Remote Viewing
Older systems without smartphone access mean you can't check your property remotely. Modern systems include app access as standard — view live feeds and receive alerts from anywhere.
Multiple Failed Cameras
If 2+ cameras have failed, repair costs approach the price of a new system. A full upgrade gives you modern cameras with improved specifications and a fresh 12-month guarantee.
System Over 7 Years Old
CCTV technology has advanced dramatically. A system from 2018 or earlier likely lacks AI detection, colour night vision, and reliable remote access. The performance gap is significant.
Unusable Night Footage
Failed IR LEDs produce dark or washed-out night footage — exactly when you need clear images most. Modern cameras with smart IR and colour night vision perform dramatically better.
