How Many CCTV Cameras Does Your Property Actually Need?
There's no universal number. The right camera count depends on entry points, blind spots, and what you actually need to prove happened. Here's how to work it out.
Start With Entry Points, Not a Target Number
The most common mistake is picking a camera count first and fitting the layout to it. A better starting point is every way in or out of the property: front door, back door, side gates, parking entrances, loading bays. Each of these needs its own camera, because a single wide shot rarely captures a face or plate clearly enough to be useful later.
Add Coverage for High-Value or High-Risk Areas
Beyond entry points, think about where loss or disputes are most likely: a till point, a stockroom, a server room, a driveway where deliveries are left unattended. These areas usually justify a dedicated camera even if they're technically visible from another angle, because a clearer, closer shot is what actually holds up when you need to review footage.
Don't Forget Overlap at Blind Spots
Corners, stairwells, and anywhere a corridor bends create blind spots that a single camera can't solve. Rather than adding more cameras everywhere, a short walk-through with a technician usually reveals two or three specific spots where an extra unit, or simply repositioning an existing one, closes the gap without inflating the whole system.
Typical Ranges by Property Type
As a rough starting point: a villa often needs 4–8 cameras covering the gate, driveway, and main entrances. A small shop typically runs 4–6, covering the entrance, till, and stockroom. Offices and warehouses vary widely with size, but usually start around 8–16 for meaningful coverage. These are starting ranges, not fixed rules. Every property still benefits from a proper walk-through.
More Cameras Isn't Always Better
Beyond a certain point, extra cameras add storage cost and monitoring effort without adding much real coverage, especially if they're duplicating an angle another camera already has. The goal is deliberate placement that answers "what do I need to see, and why," not maximum camera count.
A Site Survey Settles It Properly
Floor plans and photos only tell part of the story: sightlines, cable routes, and existing infrastructure decide the rest. A free site survey lets a technician map exactly where cameras should go and why, so you end up with a number that's based on your actual property rather than a generic guide like this one.
