computer to use as a Storage Server.

Frame Sizes

VK-64 receives each image from a Camera Server as a JPEG image. The size of the
images varies depending on the configuration of the Camera Server (the settings for Quality
and Resolution) and the complexity of the actual image.
The following tables give some typical frame sizes (in kilobytes) for various quality and
resolution values from a VB-C50i and VB150. However it is important to note that,
depending on the complexity of the image, the frame sizes may vary substantially from
those listed in the tables. For example, images of an empty corridor would typically be
smaller than these values and images of a very intricate pattern such as a crowded
shopping mall would typically be larger than these.

Every installation of VK-64 is different (due to different usage
requirements and different hardware specifications) and the figures
