CCTV Systems for UK Homes¶
CCTV (Closed-Circuit Television) systems capture video footage from cameras positioned around your property, transmitting the feed to a recording device, monitor, or cloud service. For UK homeowners, the choice comes down to four main camera types — dome, bullet, PTZ, and wireless — each suited to different use cases, mounting locations, and budgets. This guide covers everything from camera selection through UK legal compliance, installation, and cost.
UK Legal Requirement
If your CCTV cameras capture footage beyond your property boundary — including public pavements, neighbours' gardens, or communal areas — you are legally required to register with the Information Commissioner's Office (ICO), comply with UK GDPR data handling rules, and display visible signage stating that CCTV is in operation. Failure to do so can result in enforcement action and fines.
Types of CCTV Cameras: Comparison¶
| Camera Type | Best For | Pros | Cons | Typical Cost (per camera) |
|---|---|---|---|---|
| Dome | Indoor, discreet surveillance | Vandal-resistant, discreet design, wide viewing angle | Prone to IR glare in reflections, harder to clean | £40-£150 |
| Bullet | Outdoor, long-range monitoring | Visible deterrent, weatherproof, excellent night range | Bulky, more vulnerable to tampering | £50-£200 |
| PTZ | Large areas, active monitoring | Remote pan/tilt/zoom, can cover wide areas | High cost, requires active operator | £200-£800 |
| Wireless | Quick DIY installation | No cable runs, easy repositioning, app control | Battery life concerns, Wi-Fi interference risk | £60-£250 |
Dome Cameras¶
Dome cameras feature a compact, rounded housing that makes it difficult to determine which direction the lens is pointing — a psychological deterrent for potential intruders. Their vandal-resistant polycarbonate dome makes them the preferred choice for indoor mounting where physical attack is a concern. Most modern dome cameras offer wide-angle 2.8mm lenses, providing 90-110 degree fields of view suitable for open-plan areas, hallways, and reception spaces.
Best installation locations: Living rooms, hallways, landing ceilings, reception areas, shop interiors.
Bullet Cameras¶
Bullet cameras are the most recognisable CCTV form factor — cylindrical, protruding, and visibly directional. This visibility is by design: research on burglary target selection consistently shows that visible security devices act as primary deterrent cues. Bullet cameras typically have longer housings that accommodate larger lenses, giving superior long-range performance and low-light capability.
Best installation locations: Front and rear elevations, driveway monitoring, garden perimeters, garage and outbuilding coverage.
PTZ Cameras¶
Pan-Tilt-Zoom cameras provide motorised remote control over viewing direction and magnification. A single PTZ camera can replace multiple fixed cameras when actively monitored. Key features include patrol patterns (pre-set巡视 routes), auto-tracking (following moving objects), and 360-degree continuous rotation.
Best installation locations: Large gardens, commercial premises, farm and rural properties, driveways longer than 20 metres.
Wireless Cameras¶
Wireless cameras transmit video over Wi-Fi rather than coaxial or Ethernet cables, dramatically simplifying installation. The trade-off is reliance on Wi-Fi signal strength and, for battery-powered units, periodic recharging. Most modern wireless cameras offer 1080p or 2K resolution, two-way audio, and cloud recording subscriptions.
Best installation locations: Rented properties where drilling is restricted, sheds and outbuildings without existing cabling, temporary setups, flats and apartments.
CCTV Resolution Guide¶
Higher resolution means more detail, but also larger files and higher storage requirements.
| Resolution | Pixel Count | Suitability | Storage per camera per day (24/7) |
|---|---|---|---|
| 1080p (Full HD) | 1920 x 1080 | General monitoring, LPR up to 10mph | 15-25 GB (H.265) |
| 2K / 4MP | 2560 x 1440 | Better face/plate identification | 25-40 GB (H.265) |
| 4K / 8MP | 3840 x 2160 | Maximum detail, large area overview | 50-80 GB (H.265) |
| 5MP | 2592 x 1944 | Good balance of detail and storage | 30-50 GB (H.265) |
For most UK homes: 1080p is sufficient for general monitoring and identification up to 8-10 metres. If your cameras need to capture number plates or identify faces at greater distances, 4MP or higher is recommended.
UK Legal Requirements for CCTV¶
ICO Registration¶
Under the Data Protection Act 2018 and UK GDPR, you must register with the ICO if your CCTV system captures images of people outside your household — including visitors, neighbours, passers-by on public footpaths, or anyone on adjacent property. The annual fee is £40 for most domestic users, and the registration is valid for 12 months.
Signage Requirements¶
CCTV signage must be clearly visible before a person enters the camera's recording area. The sign must include:
- That CCTV is in operation
- The name and contact details of the data controller (you)
- The purpose of the recording (e.g., crime prevention)
- Information about how to request access to footage
GDPR Compliance for Footage¶
Recorded footage is classed as "personal data" when individuals can be identified. Your obligations include:
- Storing footage securely (encrypted, access-controlled)
- Retaining footage no longer than necessary (typically 14-30 days for domestic systems)
- Deleting footage when no longer needed
- Responding to Subject Access Requests within one calendar month
- Not positioning cameras to deliberately record neighbours' private spaces (gardens, windows)
Privacy Considerations¶
The ICO provides specific guidance on domestic CCTV: cameras must not be positioned to record exclusively or primarily areas beyond your property boundary. If unavoidably capturing public space, you must adjust the camera's motion detection zones to minimise unnecessary recording. The ICO can investigate complaints and has the power to serve enforcement notices requiring system modification or removal.
CCTV Installation Guide¶
Step 1: Survey Your Property¶
Walk the perimeter and identify all potential entry points: front and back doors, ground-floor windows, patio doors, side gates, garage doors, and conservatory access. Note blind spots where an intruder could approach undetected.
Step 2: Choose Camera Positions¶
For each entry point, decide between:
- Overview coverage — a wide-angle camera covering the entire approach
- Facial capture — a narrower field positioned at head height on the approach path
- Number plate capture — a low-angle (30-45 degrees) shot aimed at vehicle access points
Step 3: Cable Management¶
For wired cameras, plan your cable routes. Ethernet (PoE) cable runs should not exceed 100 metres. Use external-grade cable with UV-resistant sheathing. For cable entry into the building, use a weatherproof junction box and seal all entry points with silicone.
Step 4: Camera Height¶
Mount cameras between 2.5 and 3.5 metres above ground level — high enough to avoid vandalism but low enough to capture usable facial detail. For bullet cameras, aim slightly downward at 15-30 degrees from horizontal.
Step 5: Configure Recording¶
Set motion detection zones to avoid triggering on trees, roads, or public footpaths unless necessary. Configure recording schedules and retention periods. Test night vision by walking through the camera's field of view after dark.

CCTV FAQ¶
- Do I need to register my home CCTV with the ICO?
- Only if your cameras record beyond your property boundary. Purely domestic cameras covering only your own garden and front door generally do not require registration. The ICO provides a self-assessment tool to check your obligations.
- How long should I keep CCTV footage?
- For domestic systems, 14 to 30 days is standard. Keeping footage longer increases your data protection obligations and storage costs. Set your NVR or cloud service to auto-overwrite after your chosen retention period.
- Can my neighbour complain about my CCTV?
- Yes. If your cameras capture areas beyond your property, particularly neighbours' gardens or windows, they can raise a complaint with the ICO. The ICO will investigate and can order you to reposition, adjust, or remove cameras. This is why careful positioning and privacy masking are essential during installation.
- Are wireless cameras as good as wired?
- For image quality, wireless cameras match wired equivalents at the same resolution. The trade-offs are reliability (Wi-Fi interference, battery life) and latency. For critical security applications — particularly continuous recording — wired Power over Ethernet (PoE) systems remain more reliable. Wireless is excellent for DIY installation and rental properties.
- What is the best CCTV resolution for identifying intruders?
- For facial identification at distances under 10 metres, 1080p (Full HD) is adequate provided the camera has good low-light performance and proper positioning. For greater distances or number plate capture, 4MP or 4K is recommended, combined with appropriate lens selection and IR illumination.
