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 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.

Figure 103. Example of 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:

• Configuring Advanced Motion-Activated Relay Output on page 139

• Configuring Advanced Alarm-Activated Relay Output on page 140

• Configuring Advanced ATM/POS-Activated Relay Output on page 141

• Configuring Advanced Video Loss-Activated Relay Output on page 142
