Quick Answer
What should you get right when installing home CCTV?
Five things decide whether a home system works. Use a professional installer for cabling and configuration rather than improvising. Optimise placement so cameras cover entry points and capture faces at usable height. Protect the units and their cables from weather and tampering. Test every camera’s view, night performance, and recording before final mounting. And avoid the cheapest kits, which typically fail on low-light image quality and firmware support, the two things that matter when an incident occurs.
