What is the recommended file size for the recorded files?
The recommended file size is automatically computed by Storage Configuration screen and user should not change it to arbitrary size (because it may affect system stability). The algorithm behind recommended file size computation is accumulated from years of field experience that will allow optimal performance and manageability.
If you accidentally changed any Storage Config parameters of a particular recording directory, you can restore its default value by deleting the changed entry (such as "D:\gvrec") and click OK. The system will automatically generate default value again.
