CCTV Storage: How Much Do You Need?

CCTV is only useful if footage is there when you need it. Sizing storage correctly avoids overwriting evidence too soon.

What drives storage

Storage depends on the number of cameras, their resolution and frame rate, compression, and how many days you must retain footage. Higher resolution and longer retention multiply quickly.

Smart savings

Modern compression (H.265) and motion-based recording cut storage dramatically without losing important footage. Plan retention to match any legal or policy requirements.

Plan ahead

Always allow headroom for added cameras. Al-Gazelle sizes NVR and storage correctly as part of every CCTV design.
