BIT RATE
The bit rate is the quality of the video stream (rendered in kilobits per second). The higher the value, the higher the video quality and bandwidth
required.
NOTE: When you change any of the video stream configuration settings, the camera automatically adjusts the bit rate. If you manually reduce
the bit rate lower than the camera's automatic setting, the image quality might be reduced and the stream selection options might be limited.
I-FRAME INTERVAL
The I-frame interval configures the number of partial frames that occur between full frames in the video stream. For example, in a scene where a
door opens and a person walks through, only the movements of the door and the person are stored by the video encoder. The stationary
background that occurs in the previous partial frames is not encoded, because no changes occurred in that part of the scene. The stationary
background is only encoded in the full frames. Partial frames improve video compression rates by reducing the size of the video. As the I-frame
interval increases, the number of partial frames increases between full frames. Higher values are only recommended on networks with high
reliability. This setting is only available with H.264 and MPEG-4 compression standards.
QUALITY OF SERVICE FOR DIFFERENTIATED SERVICES CODE POINT
Quality of Service (QoS) for Differentiated Services Code Point (DSCP) is a code that allows the network to prioritize the transmission of different
types of data. This setting is only available with H.264 and MPEG-4 compression standards.
NOTES:
• If you are not familiar with DSCP, contact your network administrator before changing this setting.
• Your network must be configured to use QoS. If you are unsure if your network is QoS-aware, contact your network administrator.
ENDURA SIGNING
Enabling the Endura Signing feature allows an Endura
®
system to authenticate video from an Endura recorded stream. This setting is only
available with H.264 and MPEG-4 compression standards.
ADVANCED SHARPENING
The Advanced Sharpening setting enhances picture detail by sharpening the edges in the picture. When this mode is enabled, there is a trade-off
between image quality and the resources required for processing power. The maximum camera resolution and image rate will not be available,
but the edges of the image seem sharper. Only use this setting if you cannot achieve the sharpness level you want by adjusting the digital
processing settings of the camera. The default setting for Advanced Sharpening is Off.
