- Use the Rapid Eye Storage Estimator to forecast the length of a unit's video archive.
- Combinations of very high values be assigned only to Event Recording.
Number of Cameras, Audio
Doubling the number of cameras roughly halves the length of a unit's video archive.

Audio
At default recording values, adding audio has roughly the same effect as adding 4 cameras. If
enabled, use table
7–2, find the number of cameras connected to the unit and go the next line.
At higher recording values, audio takes a smaller percentage of the archive.
