Roughly how many days of footage will a 1tb drive store?

The answer here will be extremely "rough" because it depends on so many things. 1TB can store anywhere from 10 hours to 10 years of footage (or even much, much more).

Besides the obvious question of how many cameras, there are many other factors that determine how much footage 1TB can store:

What resolution are you recording at? 1080p requires twice as much space as 720p. Or, you can record at sub-HD resolution, or even higher than 1080p. Tweaking resolution can change the storage requirements by a factor of 20 or more.

How much are you compressing the video? High quality or high compression? This can change the storage requirements by a factor of 5 or so.

What framerate do you want? 30fps is excessive for security video, but hey some like it. 10fps is more than adequate, but you might even want to drop down to 1fps or less. This can obviously change the storage requirements by a factor of 30 or more.

Are you only recording on motion, and if so how much motion do you expect each camera to see? Some cameras might only record a few minutes a day, while others might record almost a full 24 hours. This can obviously change the storage requirements by a factor of 100 or more.



So, do you have some rough answers to these questions?
