Compression Standards
JPEG: A commonly used video compression scheme, also known as MJPEG. JPEG has the least impact
on the camera's processor, but it requires the most bandwidth.
H264: A new version of MPEG-4 compression used in high-definition video players such as Blu-ray
and HD-DVD. H.264 is the most processor-intensive, but it requires the least amount of bandwidth.
Available Camera Resolution
The resolution capabilities of the cameras are 1080P (1920 x 1080), 720P (1280 x 720), 4CIF (640 x
352), CIF (480 x 272), and QCIF (320 x 176).
Image Rate
The image rate is the number of images per second (ips) available for the video stream configuration.
Available image rates are 30, 25, 24, 15, 12.5, 12, 10, 8, 7.5, 6, 5, 4, 3, 2.5, 2, and 1.
The maximum image rate setting might not be obtainable due to the programmed compression standard
Note
and the resolution of the stream.
Refer to the following section for more information:

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.
When you change any of the video stream configuration settings, the camera automatically adjusts the
Note
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.
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.

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.
