Pelco C2631M-A Understanding the DX8100 Frame Rate Calculations, Available frame rate capacity

8.Do the following:

a.Using the ALL frame rate settings slider, set the frame rate to 30 ips. The recording rate for each enabled camera is changed to 30 ips.

b.For the ALL resolution setting, from the drop-down box, select 704 x 480 from the drop-down box. The resolution for each enabled camera is set to 704 x 480.

c.Click OK.

9.Click Apply at the Schedule page, and verify that each enabled camera listed in the site tree is configured to record at 30 ips at 4CIF.

Understanding the DX8100 Frame Rate Calculations

The DX8100 uses a complex algorithm to calculate the amount of recording resources available for each channel. This calculation takes into account factors such as 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 and table illustrates available and unavailable frame rate capacity.
