Camera installation

With the rise of smart home technology, the choice between wired Power over Ethernet (PoE) systems and wireless Wi-Fi cameras can be daunting. A professional installation ensures that your property has 100% coverage without "blind spots," while keeping cabling discreet and ensuring your system complies with UK privacy laws.

What Does the Work Involve?

• Site Survey: The installer identifies vulnerable entry points and determines the best mounting heights to prevent tampering while maximising the field of view.
• Mounting: Cameras are securely fixed to brickwork, soffits, or internal ceilings using weather-sealed brackets and backboxes to protect connections.
• Cabling: For wired systems, the pro will run Cat6 or coaxial cables through lofts, wall cavities, or discreet external trunking to a central recording hub.
• Power Supply: Connection to the mains via a fused spur or PoE (Power over Ethernet) switch, ensuring the system remains online 24/7.
• System Configuration: Setting up the Network Video Recorder (NVR), configuring motion detection zones, and setting up remote viewing on your mobile devices.
• Testing & Calibration: Adjusting lens angles, testing night vision clarity, and ensuring the "privacy masking" feature is active to avoid filming neighbours’ private property.

Typical Costs

Costs are primarily driven by the complexity of the cable runs and the quality of the hardware. While "off-the-shelf" kits are cheaper, professional-grade Hikvision or Dahua systems offer superior low-light performance and longevity, which reflects in the higher material cost.

How Long Does It Take?

• Single Wi-Fi Camera: 1–2 hours – Includes mounting, syncing to the hub, and app setup.
• Standard 2-Camera Wired System: 3–5 hours – The majority of time is spent routing cables through the loft or wall voids.
• Full 4-8 Camera System: 1–2 days – Often requires a two-person team to handle ladders and internal wiring simultaneously.
• System Upgrades: 2–4 hours – Replacing existing cameras using old cabling is significantly faster.

DIY or Professional?

Battery-powered "stick-up" cameras are well within the remit of a confident DIYer. However, for a permanent, reliable security solution, a professional installer is highly recommended. They possess the tools to drill through thick masonry safely and the expertise to secure your home network against hackers.

If your installation requires a new dedicated electrical circuit or a fused spur, this must be performed by a Part P qualified electrician to comply with UK Building Regulations.

Choosing the Right Tradesperson

• Check Accreditations: Look for installers registered with the SSAIB (Security Systems and Alarms Inspection Board) or NSI (National Security Inspectorate).
• Vetting: Ensure the installer is DBS-checked, as they will be accessing your private home and network.
• Local Knowledge: Choose someone who understands local Wi-Fi interference issues and common property layouts in your area.

Questions to ask:

• Are you installing an "open" system that I can upgrade later, or is it locked to one manufacturer?
• How much storage space is included, and how many days of footage will it hold before overwriting?
• Does the system require a monthly subscription to access all features?
• What is your policy for a "no-show" or hardware failure within the first 12 months?

UK Regulations

• Data Protection Act / GDPR: If your cameras capture images outside your property boundary (e.g., a public pavement), you become a "data controller" and must follow ICO guidelines.
• Privacy Signs: While not strictly mandatory for domestic homes not capturing public space, signs are recommended to avoid disputes and enhance deterrence.
• Building Regs (Part P): Any 230V mains electrical work must be certified.
• Right to Privacy: You must ensure cameras are not pointed directly into a neighbour's windows or private garden.

Common Problems

• Spider Webs & Insects: Infrared lights attract bugs, which can trigger false alarms; professional installers use "EXIR" technology to minimise this.
• Poor Night Vision: Placing a camera behind a glass window causes "IR bounce-back," resulting in a white blur; cameras should always be mounted externally.
• Weak Wi-Fi: High-resolution video requires strong upload speeds; a pro will install Wi-Fi extenders or use hardwired PoE to prevent signal dropouts.
• Cable Decay: Using cheap internal-grade cables for external runs leads to water ingress and signal loss within 12-24 months.

Frequently Asked Questions

Do I need planning permission for CCTV?

In most cases, no. CCTV is usually considered "permitted development." However, if you live in a listed building or a conservation area, you should check with your local council before drilling into the facade.

Can my neighbours complain about my cameras?

Yes, if the cameras infringe on their privacy. Use the "Privacy Masking" feature in your camera settings to black out their windows or garden, and be prepared to show them the field of view to maintain good relations.

Will CCTV work if my internet goes down?

Wired NVR systems will continue to record locally to the hard drive even without internet. You only lose the ability to view live footage remotely on your phone until the connection is restored.

How much storage do I actually need?

For a 4-camera 4K system, a 2TB hard drive typically provides about 7–10 days of continuous recording. If set to "motion-only" recording, this can extend to several months.

Is there a monthly fee for CCTV?

Professional NVR systems generally have no monthly fees. However, "smart" brands like Ring, Arlo, or Nest usually require a subscription (approx. £3–£10/month) to save and view recorded clips in the cloud.
