Example. If the size of a hard drive, for instance, is 40 GB, 4 cameras are continuously recording PAL video signals with 10 frames per second and 150Kb 150 Kb frame size. Based on the formula, you work out:

...

Info
titleNote.
To calculate the size of a hard drive, the following specific features should be accounted for: 1) About 5-10% of the hard drive size is taken up by the filing subsystem data. To ensure that Windows OS is operating properly, at least 20% of free disk space is required. By default, Windows OS auxiliary files are assigned 1000Mb1000 Mb. To modify the above value, Windows OS catalogue should be updated, using Tweaki.exe utility, supplied together with the Axxon PSIM distribution software package.
