A Homeowner's Guide to CCTV: What to Consider Before You Buy
CCTV has gone from a niche security purchase to something a lot of homeowners just consider part of a decent front-door setup. Before you buy the first system that comes up in a search, here's what actually affects whether it's useful.
Wired vs wireless
Wireless (WiFi) cameras are far easier to install and are the obvious choice for renters or a quick single-camera setup, but they depend entirely on your WiFi coverage and battery life, and can be jammed or disrupted. A wired system, with cameras running back to a central recorder, is more effort to install but is far more reliable for a permanent, whole-property setup, and doesn't rely on your home broadband to keep recording.
Local storage vs cloud
Local storage (an SD card or a network video recorder on site) means no ongoing subscription and no dependence on an internet connection to retrieve footage, but if the recorder itself is stolen or damaged, the footage goes with it. Cloud storage protects against that and usually adds smarter motion detection, but comes with a monthly cost and needs a reliable internet connection to work properly.
Resolution and field of view matter more than camera count
Two well-placed, high-resolution cameras covering your front door and driveway will be more useful as evidence than six cheap, low-resolution ones scattered around the garden. Prioritise a camera that clearly captures faces and number plates at your property's actual distances, not just a wide-angle view.
Know the legal side
Cameras should be angled to cover your own property, not directly into a neighbour's windows or garden.
If footage could capture a public footpath or a neighbour's property incidentally, UK data protection guidance recommends clear signage.
If in doubt, the ICO (Information Commissioner's Office) publishes straightforward guidance for home CCTV owners.
Get it installed properly
Even a DIY-friendly wireless system benefits from a professional doing the initial placement and cable runs, particularly for anything wired back through the loft or external walls.
