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. Common Issues We Fix ### We've Seen It All CCTV not recording — hard drive failure, storage full, or settings issue Camera showing black screen or 'no signal' on one or more channels Poor image quality — blurry, foggy, or degraded footage Night vision not working — IR LEDs failed or blocked App not connecting — network changes or router replacement False alerts and excessive notifications flooding your phone Water damage to external cameras — seal failure or condensation System too old — analogue cameras producing unusable footage [Read our CCTV troubleshooting guide](/blog/cctv-not-recording-troubleshooting-guide) Our Services ## Repair, Maintain, or Upgrade Three service tiers to keep your CCTV system working at its best — from emergency repairs to planned maintenance and full system upgrades. ### CCTV Repair Diagnose and fix faults on any CCTV system.

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. Upgrades ### 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](/services/cctv-installation) 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. ![Eagle All Security engineer configuring a CCTV system after upgrade](/assets/alarm-panel-eagle-BenLZMf_.jpg)![Security engineer on ladder installing upgraded CCTV camera](/assets/bellbox-ladder-BkF0HUKO.jpg) Pricing ## 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. #### Diagnostic & Simple Fix £80–£150 Settings reconfiguration, network reconnection, firmware update, app setup. Most software and configuration issues resolved in a single visit. #### Camera Replacement £120–£250 Replace a failed camera with a matched or upgraded unit. Includes camera, mounting, cable testing, and NVR configuration. #### Hard Drive Replacement £80–£150 Replace failed NVR/DVR hard drive. Includes surveillance-grade drive, installation, and recording verification. #### Annual Maintenance From £150/year Scheduled service visit, lens cleaning, recording check, firmware update, night vision test, cable inspection. Priority callout response. #### Full System Upgrade From £500+ Replace outdated cameras and recorder with modern 2K/4K system. Free survey, fixed quote, 12-month guarantee. Reuses existing cables where possible. How It Works ## 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. Repair Process ### Step by Step 01 #### 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. 02 #### 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. 03 #### 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. 04 #### 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. 05 #### 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. Upgrade Guide ## 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.
