Average frame size of 640х480 640x480 resolution is:
Average frame size may vary over a wide range depending on the vendor, the model and the settings of the camera and video image complexity. |

To calculate the frame size you can use the ratio, that when increasing the vertical or horizontal resolution two times, the average frame size will be increased four times (this rule is a relative and can be applied only to some camera models). |
Examples of calculating the capacity of the disk subsystem (without the capacity of the system log and metadata databases) are presented below.
