The short answer
The right home CCTV system is the one that covers the views your property actually needs at a resolution and storage setup you can live with — not simply the largest package on offer. For most homes that means a four-camera system covering the main entrances and approaches, in HD or higher resolution for clear, usable footage, with cameras that have night vision for after-dark cover. You then choose between local storage (a one-off recorder) and cloud storage (an ongoing subscription), and between wired reliability and wireless flexibility. The honest answer is to start from the views you need and the way you want to run it, and let those decide the camera count, resolution and storage — rather than a fixed package.
There is no single system that suits every home — the right one depends on what you need to see, how you want to store footage, and whether reliability or easy installation matters more. Here is how to weigh it.

- Storagelocal recorder vs cloud subscription
- Night visionfor after-dark cover
- Connectionwired reliability vs wireless flexibility
What to look for
- Coverage: start from the views that matter — front and back doors, side access, driveways and any blind spots — and size the camera count to those, not to the kit's maximum.
- Resolution: HD or higher gives footage clear enough to be useful; very low-resolution cameras can record an event without capturing usable detail.
- Storage: a local recorder is a one-off cost you own, while cloud storage adds a recurring subscription but keeps footage off-site.
- Night vision: infrared or low-light cameras matter for the hours most incidents happen.
- Wired or wireless: choose reliability or easy installation based on your property (see the wired vs wireless page).
| Feature | Sensible home choice | Why |
|---|---|---|
| Cameras | around four for most homes | covers main entrances & approaches |
| Resolution | HD or higher | footage clear enough to be useful |
| Storage | local recorder or cloud | one-off cost vs off-site subscription |
| Night vision | infrared / low-light | covers after-dark hours |

How to match it to your property
A small flat with one entrance needs far less than a detached house with a driveway, side gate and large garden. Map the approaches and blind spots first, then choose a camera count that covers them — often around four for a typical house. Decide how you will store and review footage, since that drives the recorder-versus-cloud choice and any ongoing cost. Then pick wired or wireless based on how much reliability and footage quality you want against how disruptive the install can be. Matching the system to the property this way usually beats buying the biggest advertised package.

Frequently asked questions
What CCTV system is right for a home?
For most homes, a four-camera system covering the main entrances and approaches, in HD or higher resolution and with night vision, is a sensible starting point. You then choose local or cloud storage and wired or wireless, matched to your property and how you want to run it, rather than buying the largest package on offer.
How many CCTV cameras does a house need?
Around four covers the main entrances and approaches of a typical house, but it depends on your layout — a small flat may need one or two, while a detached home with a driveway, side gate and garden may need more. Map the views and blind spots first, then size the camera count to them.
Is local or cloud storage better for home CCTV?
Both work — it is a trade-off. A local recorder is a one-off cost you own and keep on site, while cloud storage adds a recurring subscription but keeps footage off-site in case the recorder is taken or damaged. Some systems combine the two.
