How Many CCTV Cameras Do I Need for My Home UK | Security Camera Installation South London SW SE CR SM KT | Home Surveillance System Wandsworth Lambeth Southwark Croydon Merton Sutton Kingston

This is one of the first questions homeowners ask when they start thinking about installing a security camera system near me — and it’s the right question to ask before anything else. The number of cameras you need depends on four things: the size of your property, the number of entry points, your property type, and how much coverage you want between “covered” and “fully monitored.” There’s no single correct answer — but there are clear starting points depending on your situation. Here’s a practical breakdown for South London homeowners.

---

For most residential properties in South London, two cameras cover the essentials: one covering the front door and one covering the back of the property — rear gate, back garden, or side access. This configuration closes the two most common entry points burglars use.

If your property has a driveway, a third camera covering the driveway approach is strongly recommended. A driveway camera captures anyone approaching the vehicle or front entrance before they reach the door — giving you earlier visibility and a wider evidence window if something happens.

The practical minimum for most South London terraced houses is therefore 2–3 cameras, covering front door, rear access, and driveway where applicable.

Different property layouts have different vulnerabilities. Here’s what we typically recommend by property type:

Terraced house (2 bed / 3 bed): 2–3 cameras. Front door coverage, rear garden or back gate, and a wide-angle side passage camera if there’s side access between properties. This is the most common configuration we install across Wandsworth, Lambeth, and Southwark.

Semi-detached house: 3–4 cameras. Front door, driveway, rear garden, and a side gate or side passage camera. Semi-detached properties have more perimeter to cover — the side of the property is often a blind spot without a dedicated camera.

Detached house: 4–6 cameras. Full perimeter coverage — front, rear, both sides, driveway approach. Detached properties in areas like Wimbledon, Kingston, or Epsom typically have larger gardens and longer driveways that require additional coverage to avoid blind spots.

Flat (ground floor): 2 cameras. Front entrance and any private outdoor space or parking. Upper-floor flats rarely need external cameras unless there’s a shared entrance or communal car park.

HMO or multi-occupancy property: 4–6 cameras minimum. Internal common areas (entrance hallway, communal kitchen, stairwell) plus external perimeter. Landlords and HMO operators have additional GDPR obligations for internal cameras — we advise on compliant positioning during every free site survey.

Not necessarily. Camera placement matters more than camera count. A single well-positioned camera covering the main entry point provides more practical security value than four cameras with overlapping fields of view and blind spots on the approach.

The most common mistake in DIY installations is positioning cameras too high — capturing rooflines rather than faces — or pointing them directly into light sources, which washes out the image. A professional site survey identifies the exact positioning that gives you maximum coverage from minimum hardware.

That said, there’s a legitimate argument for a higher camera count when you want complete perimeter visibility with no gaps — particularly for larger properties, properties in areas with higher local crime rates, or landlords who need footage of all entry and exit points for insurance and liability purposes.

Our installation packages are built around a standard 4-camera configuration — which covers the majority of South London residential properties comprehensively. Both the Basic and Standard packages include 4 cameras as the base configuration, with the option to expand if your property needs it.

Our standard packages include 4 cameras, which for most properties provides full perimeter coverage:

Camera 1 — front door (captures faces, packages, approach) Camera 2 — driveway or front of property (wider field, vehicle capture) Camera 3 — rear garden (back gate, rear access, garden) Camera 4 — side passage or side gate (the most commonly overlooked entry point)

This configuration leaves no blind spots on a typical terraced or semi-detached property. For detached properties or larger homes, a 6–8 camera configuration may be more appropriate — something we assess during the site survey.

The Standard Package uses Hikvision 5MP dome cameras — wired, weatherproof, with colour night vision — which gives clear facial recognition quality footage at all four positions. The Basic Package uses Hiseeu 3K PTZ wireless cameras with a 10″ monitor — a strong option where cable routing is impractical.

For most homeowners the answer is no — external cameras covering entry points provide the deterrent and evidence capture that matters most. Internal cameras add value in specific situations:

• HMO and rental properties — landlords often install internal cameras in communal hallways and staircases to monitor access and protect against damage claims
• Home offices or high-value storage areas — where specific internal rooms need monitoring
• Properties with frequent deliveries or contractors — an internal entrance hallway camera adds a secondary layer

Internal cameras raise additional privacy considerations, particularly in shared or rented properties. We discuss positioning and compliance as part of every installation — all our systems are fully ICO compliant.

The best way to determine exactly how many cameras you need is a free site survey — one of our South London engineers visits your property, walks the perimeter, identifies entry points and blind spots, and recommends the minimum camera configuration that gives you complete coverage.

There’s no obligation and no hard sell. Most homeowners come away with a clear picture of what they actually need — which is often simpler and more affordable than they expected.
