The DX8100 uses a complex algorithm to calculate the amount of recording resources available for each channel. This calculation takes into

account factors such the number of enabled cameras, whether uniform or mixed resolution values are used, recording type (continuous, alarm, or

motion), and the frame rate settings of enabled channels. The resulting calculations provide the operator with a margin of available frame rate

capacity to distribute among the recorder’s channels. This margin of frame rate capacity, or “headroom,” is presented to the user as color-filled

sections of the frame rate sliders. White areas on the slider represent frame rate capacity that is not available to that channel. In certain cases,

adjusting the available frame rates of one channel or resolution type may free up capacity for other channels. The following figure illustrates

available and unavailable frame rate capacity.
