WPS-550-DOM-IP Installation Manual
9.4.4. Video Streaming 1 and 2 Setup
Note:
Streaming 1 and 2 settings are identical. Settings options have only been covered once.
Basic/
Advanced
Mode
Set the streaming mode to “Advanced” to allow fine control of streaming parameters. Extra options for Advanced
mode are indicated below.
Resolution 176x144 , 320x240, 640x480, 1280x720 (default)
Profile
Main
Main: This profile provides higher overall video quality and better video compression,
which requires robust processing to decode in real-time. This profile should be used
in conjunction with a Wirepath NVR or in stand-alone applications when maximum
video quality is paramount.
Baseline
Baseline: This profile provides slightly lower quality and less compression, making
it easier for less-robust processors to decode in real-time. This profile may provide
benefits in stand-alone applications without a Wirepath NVR, when camera will be
configured primarily for non-HD resolutions, or when remote or mobile device access
is a priority.
Bitrate
Control Mode
(Advanced Mode only)
CBR – (Constant Bitrate) Bitrate of the image will remain constant regardless of
image complexity. Provides a fixed, known bandwidth use.
VBR – (Variable Bitrate) Bitrate of image increases and decreases based on image
complexity. A higher quality image can be transmitted but during complex scenes
bandwidth use increases.
Video
Quantitative
Changes the range of VBR bitrate to Low or High.
• In “Basic” mode, settings range from Low (slowest) - Medium - Standard - High - Best (fastest).
• In “Advanced” mode, quality may be set from 1 (slowest) to 9 (fastest).
When this setting is changed, Bitrate Control Mode automatically changes to VBR, and the bitrate will increase
or decrease depending on the select option.
This setting will change if the camera is enabled or modified from a Wirepath™ NVR, since the NVR
requires a CBR stream.
Video Bitrate
(Advanced Mode Only) Sets the fixed bitrate to use when CBR is selected for bitrate control. The recommend
setting is 1, 2, 4, 6 or 8 Mbps for compatibility with Wirepath NVRs.
Video Frame
Rate
Adjusts the bitrate from 5 FPS to 30 FPS for streaming 1, and from 5FPS to 15FPS for Streaming 2. Higher
FPS (Frames Per Second) provides a smoother image but some display interfaces or devices may not be able
to support the higher rate.
Use the defaults 30 FPS (Streaming 1) and 15 FPS (Streaming 2) unless video display problems occur.
