How do I work out how much storage I need?

Storage requirements depend on

  • whether you set it at 24/7 recording or motion only
  • whether you choose H265+ or H264
  • The frame rate
  • The resolution you choose to record at

The above is a useful url.

For example, if you have 5 cams@ 6MP resolution @ 25fps @ 24/7 recording, you will have 2 weeks:

5 cams @ 24/7 @ h265 @ 25fps @ 6MP resolution
8 cams @ H265 @ 20fps @ 24/7 @ 8MP resolution
