Short answer: a video doorbell is the easiest way to see who is at your front door, but it only covers that one spot. A CCTV system covers the whole property and usually stores footage locally. For most homes the best answer is both: a doorbell at the front, and a few cameras covering the driveway, sides and rear.
Video doorbells have become one of the most popular home security purchases. They are cheap to start with, simple to fit and give you a live view on your phone. But they are not the same thing as a CCTV system, and it helps to understand what each one does well before you decide.
What a video doorbell does well
- Speaks to visitors. You can see and talk to someone at the door from anywhere, which is useful for deliveries and deterring callers.
- Simple installation. Battery or wired models can go up in an hour.
- Alerts. Motion and button-press alerts arrive on your phone.
Where a doorbell falls short
- One viewpoint. It covers the front door only. Side gates, back doors and driveways are not seen.
- Battery models. They need recharging and may miss events in sleep mode.
- Cloud storage. Saved clips often need a subscription.
- WiFi dependent. A weak signal at the front door is one of the most common causes of missed alerts.
What a CCTV system does well
- Whole-property coverage. Several cameras can cover the front, sides, rear and driveway.
- Local recording. Footage is usually kept on a recorder in your home, with no monthly charge.
- Wired reliability. PoE cameras get power and data through one cable and do not depend on WiFi.
- Higher quality. Better lenses, night vision and storage give more usable footage.
Where CCTV has drawbacks
- It costs more to install, and wired cameras need cable runs.
- It needs a recorder, a hard drive and a little planning.
- It is a bigger job than putting up a doorbell.

Privacy and the law in the UK
Both doorbells and cameras are covered by the same rules. If your camera records only your own property, it is generally treated as domestic. If it captures the street, a neighbour’s house or garden, UK data protection law may apply and you need to use the system responsibly. In a 2021 county court case, a neighbour’s doorbell and cameras were ruled to have breached data protection law. Pointing cameras carefully, using privacy masking and putting up signs all help. We cover this in home CCTV in Essex: what to know before you buy.
Why many homes use both
A doorbell is brilliant at the front door. A few well-placed cameras fill in the gaps and keep footage safe on a local recorder. If you are not sure whether to go wired or wireless, our guide to wired versus wireless CCTV cameras will help, and where to place CCTV cameras shows how to get the most from each one.
