How many days will I get out of different hard drive sizes?


*NOTE: ALL storage calculators are approximate, as there are many variables which affect the actual results. One of the most overlooked variables is the amount of activity which the camera sees. When there is little motion and activity in the camera’s view, the compression is more efficient and the HDD use decreases. The more motion on-camera, the more HDD space is used. This calculator uses HIGH motion at ALL TIMES to calculate HDD usage. Most users will in fact get MORE time out of a hard drive than stated here in this calculator, as most users do not have high motion in front of a camera 24 hours each day. These results are for approximate HDD sizing only. Always check to see how much recording time you get from your recorder and adjust settings as needed to achieve the desired amount of backup in your recorder.
