CONFIGURING A CUSTOM VIDEO STREAM CONFIGURATION
1. Place your mouse pointer over the A/V Streams tab.
2. Select Video Configuration from the drop-down menu.
3. Click both of the Clear buttons to delete the primary and secondary streams settings.
4. Optional: In the Primary Stream section, type a user-friendly name in the Name box (2 to 64 characters). A user-friendly name makes it
easier to recognize the stream (for example, Live and Recording).
5. Configure the Compression Standard, Resolution, Image Rate, Bit Rate, and I-frame Interval settings for the primary stream.
NOTE: The compression standard, resolution, image rate, bit rate, and I-frame interval settings are dependent on each other. You must first
decide the priority setting before you configure a stream. For example, if you want an image rate of 30 ips, set the image rate before you
configure the other settings.
6. For the H.264 compression standard, configure the additional QoS (DSCP) Codepoint, Endura Signing, Profile, and Rate Control settings.
7. Repeat steps 3 to 6 for the Secondary stream.
8. Click the Save button to save the settings, or click the Reset button to clear all of the information you entered without saving it.
COMPRESSION STANDARDS
JPEG: A commonly used video compression scheme. JPEG has the least impact on the camera’s processor, but it requires the most bandwidth.
MJPEG: Motion JPEG has the same characteristics as JPEG but differs in its mode of transfer (RTP).
H.264: Also known as MPEG-4 Part 10 or Advanced Video Coding (AVC), H.264 is one of the most widely used compression, recording, and
distribution methodologies for High Definition (HD) video. It is used in Blu-ray
video players and by companies that transmit HD video or movies
over the internet and by satellite. H.264 is the most processor-intensive compression standard, but it requires the least amount of bandwidth.
RESOLUTION AND RECOMMENDED BIT AND IMAGE RATES
Refer to the following table for the resolution capabilities, recommended bit rates, and maximum image rates of your camera model.
Table B. Camera Resolutions and Bit and Image Rates
IMAGE RATE
The image rate is the number of images per second (ips) available for the video stream configuration. Available image rates depend upon the
model of the device that you are using.
NOTE: The maximum image rate setting might not be obtainable due to the compression standard and the resolution of the stream.
