How Many CCTV Cameras Do I Need?

A practical starting point for estimating camera count before a site assessment confirms the exact number for your property.

Camera count depends on entry points and areas you want covered — a villa might start around 4-8 cameras, an apartment 2-4, a small office 4-6 and a retail unit 4-10, as illustrative starting points only. The actual count is confirmed during a site assessment of your specific layout.

Think entry points and sightlines, not room counts

Camera count is driven less by how many rooms a property has and more by how many entry points, corridors and open areas need a clear line of sight. A single camera positioned well can cover a wide area, while a poorly placed one may leave blind spots even with more cameras added. The examples below are illustrative starting points, not a formula — an actual count is confirmed once we've seen the property.

Villa

A typical starting point covers the main entrance, driveway or gate, garden or yard areas, and any secondary doors, with additional cameras for larger perimeters or multiple building wings.

Apartment

Apartments generally need fewer cameras, often focused on the front door and, where permitted by the building, a balcony or external access point.

Small office

A starting point typically covers the main entrance, reception area, corridors leading to sensitive rooms, and any stock or equipment storage areas.

Retail unit

Retail coverage usually includes entrances, till or counter areas, aisles and stockroom access, with the exact count depending on the shop's size and layout.

Why a site assessment matters

Ceiling height, obstructions, lighting and cable routing all affect how many cameras are actually needed to cover a space without gaps. These figures are a planning reference, not a guaranteed count — the confirmed number comes from assessing your property directly.
