Video Doorbell vs Professional CCTV: Do You Need Both?
By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
Quick answer
They're different products: a video doorbell is a door-answering device with a camera — superb for parcels, callers and the doorstep conversation; professional CCTV is continuous, multi-angle evidence and deterrence for the whole property. A doorbell alone leaves sides, rear and driveway dark — which is where burglars actually enter. Most homes are best served by both: doorbell for the door, wired CCTV for coverage.
What each does well
| Video doorbell | Professional CCTV | |
|---|---|---|
| Core job | Answer the door from anywhere | Continuous recorded coverage |
| Coverage | Doorstep cone only | All approaches and vulnerable points |
| Recording | Motion clips (subscription for history) | 24/7 to your own NVR, 30+ days |
| Evidence quality | Faces at the door: good; beyond 3–4m: poor | Identification-grade where designed |
| Resilience | WiFi + battery + cloud dependent | Wired, local storage, UPS-able |
| Deterrence | Mild (familiar, door-only) | Strong, visible, whole-property |
| Running cost | £0–£8/month subscriptions | None required |
Where doorbell-only homes get caught out
Burglary patterns are stubborn: most entries are rear or side — patio doors, side gates, kitchen windows — exactly the zones a doorbell never sees. Doorbell limitations compound at the worst moments: clip-based recording misses the approach, WiFi dropouts and dead batteries happen on cold nights, cloud history needs the subscription you lapsed, and a knocked-off or stolen doorbell takes its evidence with it (wired PoE cameras keep footage on the NVR regardless). None of this makes doorbells bad — it makes them one camera, at the one entrance burglars use least.
The hybrid setup that actually covers a home
Keep (or add) the doorbell for what it's for — deliveries, callers, the intercom function — and put wired coverage where risk lives: driveway/front overview, rear garden, side passage, any detached garage. A 3–4 camera PoE system from £600–£1,500 installed alongside your existing doorbell covers the classic entry routes with continuous local recording and no monthly fees. Integration tip: keep doorbell notifications people-only and let the CCTV app handle perimeter alerts — separate tools, separate jobs, no notification fatigue.
