Operation Guideline for Recording and Viewing Recording Frame Rate Adjustment ● Reduce recording frame rate when disk is under high load in the Storage Server Configuration dialog (➝ P. 57) * This option is enabled by default (recommended). When the network recording software writes images received from cameras into the hard disk, if the load (mainly the load of writing into the hard disk) of the PC on which the Storage Server is running is too high, the software cannot write the images immediately. If the amount of the image that is waiting to be written increases for a certain period of time, the Storage Server considers the PC to be highly loaded. When this happens, the Storage Server stores images at intervals rather than storing all of the images the Storage Server received, in order to reduce the PC load. If you use this function, you can avoid recording failure as much as possible even if your PC temporarily becomes highly loaded for some reasons. When using this setting, adjust the video recording frame rate so that it does not drop below 0.5 fps. Note that events are generated when the network recording software starts and ends the operation of the function (➝ P. 288, "Changing the Recording Frame Rate"). You can check the operating status of the function via the Event Search dialog (➝ P. 214). If you do not use this function, recording may be interrupted when the load on your PC is high. This software cannot detect the recording interruption. This function is disabled when the Resolution is set to MPEG-4. 224
