I work with the cameras, connections, and settings that make a CCTV system useful day to day. Every install is planned around clean cable runs, solid mounts, and equipment that stays dependable long after handover.
A security camera is only worth its cost when it performs on the day it is needed. I treat each system as utility equipment: mounted securely, powered reliably, and set up so its footage can be found and played back without guesswork.
My advice is independent of any proprietary surveillance subscription. I recommend the hardware and settings that suit the building, and I explain the trade-offs so you can decide with clear information.
