Understanding the DX8000 Frame Rate Calculations

The DX8000 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 t o 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.

The following table describes available and unavailable frame rate capacity.

SETTING UP ADVANCED RELAY OUTPUT

Relays work much like switches. When triggered, relays can activate external devices, such as sirens, light fixtures, and door locks. The DX8000
Series DVR allows Administrators and Power users to link relays to cameras and alarms. Up to 20 seconds of delay can be set from the moment
an event is triggered to the time when a relay is activated.
Make sure you have linked relays to the appropriate cameras and alarm inputs before attempting to configure them. For instructions on linking
alarms and relays, refer to Linking Alarm Inputs to a Camera on page 33 and Linking Relay Outputs to Alarm Inputs on page 33.
This section describes how to setup advanced alarm and motion relay output and includes the following topics:
