Storage depends on more than camera count
The amount of CCTV storage you need depends on camera quantity, image quality, frame rate, recording behaviour, and how long footage needs to be retained. Two systems with the same number of cameras can have very different storage demands depending on how they are configured.
Questions that shape storage planning
- How many cameras are recording?
- What resolution and recording quality is required?
- Is the system recording constantly or only on events?
- How many days or weeks of footage need to be kept?
- Are some cameras more important than others for evidence quality?
Plan storage early, not after installation
Storage is easier to get right when it is considered as part of the system design rather than as an afterthought. Otherwise, clients often end up with either less retention than expected or unnecessary spend in the wrong places.
