When the remaining space falls below the specified value, the event will be displayed and a notification will be e-mailed ( P. 3-5, P. 3-23). 4. [Reduce recording frame rate when disk is under high load] - When disk is highly loaded, recording frame rate is temporarily reduced to prevent the recording from stopped. See Chapter 6 for details. This function is available for JPEG video recording. It cannot be used for MPEG-4 video recording (VB-C500VD, VB-C500D, VB-C60). Tip If [Reduce recording frame rate when disk is under high load] is selected, you will receive an event notification such as "Effective Recording rate (  %)" when the recording frame rate drops. Ex. Effective Recording rate (100.0  90.0 %) Note When the free disk space has fallen below the value specified in the [Low disk space warning level] field, an event occurs and an event notification mail is sent. Also, if the used disk space exceeds the value specified in the [Maximum disk space used] field, recorded video will not be saved until the required free disk space is secured.
