Repair your CCTV system.

Modern security systems range from simple Wi-Fi cameras to complex hardwired IP networks. Professional repair ensures that the delicate balance of data transmission, power supply, and storage remains stable, providing you with high-definition evidence should the worst happen.

What Does the Work Involve?

• System Diagnostics: Testing the DVR/NVR (recorder) and power supply units to identify hardware or software failures.
• Physical Inspection: Checking external camera housings for water ingress, loose brackets, or lens damage.
• Signal Testing: Using specialised monitors to test the video feed at the camera head versus the recorder to find cable breaks.
• Connection Maintenance: Stripping and re-terminating corroded BNC or RJ45 connectors and clearing debris from junction boxes.
• Software Updates: Patching firmware to fix bugs, improve cybersecurity, and ensure remote viewing apps work correctly.
• Image Optimisation: Cleaning lenses, adjusting focal lengths, and recalibrating infrared (IR) settings for better night vision.

Typical Costs

The cost of CCTV repair depends heavily on the type of system (Analogue vs IP) and the height at which cameras are mounted. Most UK technicians charge a fixed call-out fee that covers the first hour of diagnostics.

Price factors include the need for specialist access equipment (like cherry pickers for high-mounted cameras), the age of the system (obsolete parts may require full replacements), and the distance between the cameras and the recorder.

How Long Does It Take?

• Basic Diagnostic & Software Reset: 45–60 minutes.
• Single Camera Replacement: 1–2 hours (including ladder work and configuration).
• Hard Drive Replacement & Formatting: 1 hour.
• Tracing Complex Wiring Faults: 2–4 hours depending on the size of the property.
• Full System Health Check (4-8 Cameras): 2–3 hours.

DIY or Professional?

Homeowners can handle basic maintenance such as cleaning lenses with a soft cloth or checking that the recorder is plugged in. However, most repairs require a professional. CCTV systems involve working at height, handling delicate low-voltage electronics, and configuring network settings that can be easily "bricked" by an amateur.

If your system is hardwired into your consumer unit (fuse box), a professional with Part P electrical knowledge should handle the power supply repairs to ensure safety and compliance.

Choosing the Right Tradesperson

• Accreditations: Look for companies registered with the SSAIB (Security Systems and Alarms Inspection Board) or NSI (National Security Inspectorate).
• DBS Checked: Ensure the technician has been background-checked, as they are accessing your home's security infrastructure.
• Questions to Ask:
  • Are you experienced with my specific brand (e.g., Hikvision, Dahua, Reolink)?
  • Do you offer a warranty on both the replacement parts and your labour?
  • Will you show me how to use the remote viewing app after the repair?
  • Is the replacement hardware "surveillance grade" or standard consumer grade?

UK Regulations

• Data Protection Act / GDPR: If your cameras overlook public spaces or a neighbour's garden, your system must comply with ICO (Information Commissioner's Office) guidelines.
• BS EN 62676: The British Standard for video surveillance systems. Professional installers should aim for these performance benchmarks.
• Privacy Signage: In some residential contexts, particularly if the cameras capture public footpaths, you may be required to display a small sign.

Common Problems

• Spider Webs: Insects are attracted to the heat of IR LEDs; webs can trigger false motion alerts and blur images. Regular cleaning prevents this.
• Failing Hard Drives: CCTV drives run 24/7 and usually fail every 3-5 years. If your system isn't recording, this is the most likely culprit.
• Power Surges: UK storms can fry power supply units (PSUs). Installing a surge-protected power strip is a cheap way to avoid expensive repairs.
• Corroded Connectors: If external junction boxes aren't IP66-rated, moisture will eat through the copper connections, causing "flickering" video.
