How Many CCTV Cameras Do I Need? (Home & Business)
Share
Most UK homes are well covered by 4 to 6 cameras - one for each entry point and key area you want to see clearly. The right number isn't about blanket coverage; it's about covering the spots that matter: doors, driveway, side access and gardens.
Typical numbers by property
| Property | Typical cameras |
|---|---|
| Flat / small home | 2 to 4 |
| 3 to 4 bed house | 4 to 6 |
| Large house / corner plot | 6 to 8 |
| Small shop or office | 4 to 8 |
| Larger commercial site | 8 to 16 |
How to work it out
Walk your property and list every point you'd want on camera: front door, back door, driveway, side gate, garden, and (for a business) the till and stockroom. Plan one camera per point. That list is your camera count.
Leave room to grow
Your cameras have to fit your recorder's channels. Buying a recorder with spare channels - say an 8-channel NVR with 4 cameras now - lets you add more later without replacing the kit. What NVR do I need?
Cover more with the right camera
Turret and bullet cameras suit long views like driveways; wide-angle cameras cover open areas like a garden in one shot, sometimes reducing how many you need. Camera types explained.

Frequently asked questions
Is 4 cameras enough for a house?
For many 3 to 4 bed homes, yes - 4 cameras can cover the front door, back door, driveway and a side access. Larger homes often benefit from 6.
Can I add cameras later?
Yes, as long as your recorder has spare channels. Buying an 8-channel NVR even if you start with 4 cameras makes adding more easy.
How far can one CCTV camera see?
A typical fixed-lens camera gives clear identification up to around 10 to 15 metres; it can see further but with less detail. Night-vision range varies by model.
