IP Camera vs Analog CCTV Camera
Analog HD cameras (HD-TVI, HDCVI, AHD) send video over coaxial cable to a DVR. IP cameras send digital video over network cable to an NVR, a router or the cloud.

Picture quality
IP cameras usually give higher resolution (4–8 MP and 4K) and smarter features such as person and vehicle detection. Analog HD cameras are commonly 2–5 MP.
Cables and installation
IP cameras use one Cat6 PoE cable for power and data. Analog cameras use coaxial cable plus separate power.
Cost
Analog systems are cheaper to start; IP systems cost more but scale better and are easier to upgrade.
Wi-Fi cameras
Wi-Fi cameras are IP cameras that connect wirelessly. They are ideal for homes with a few cameras; see Wi-Fi cameras.
Our advice
Choose IP (with an NVR) for new shops and offices; Wi-Fi cameras for small homes; keep analog only to extend an existing DVR system. See IP cameras.
