WPS-300-ENC-4IP Installation Manual
12.8- Video Settings
Pg. 28
The Encoder supports up to 4 streams that can be used for streaming to a mobile device, network recorder,
control system GUI, or the browser GUI simultaneously. While the highest quality is desired, it may not be
supported by the network or device, and will also have a larger storage size. Use this menu to adjust the
resolution, and the amount of streams available.
Channel
Selects the channel to configure.
Video System
Sets the type of video format of the BNC Video Inputs and Outputs, NTSC or PAL.
Note: Changing this setting will cause the picture to be lost if the selected
format is not supported by the display method. Do not change this setting
unless it is a requirement of the system.
Streams
Select Single or Dual streams.
12.8.1- Streaming 1 & Streaming 2
Resolution
Available Resolutions (High to Low Quality):
Bitrate
CBR (Constant Bitrate)
Control
Bit rate of the image will remain constant regardless of the complexity of the image.
Allows for a fixed, known bandwidth use.
VBR (Variable Bitrate)
Bit rate of image increases and decreases based on the complexity of the image
maintaining a higher quality image during complex scenes but reducing bandwidth use
during less-complex scenes.
See section
tradeoffs between the settings.
Note: This setting will change to CBR whenever the Encoder is enabled or
modified from an NVR.
Video Quality
Changes the range of VBR bitrate change based on a level from Low to High. In Basic
mode the options range from Low (slowest) to Best (fastest) bitrates, while in advanced
mode the options range 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.
Note: This setting will change whenever the Encoder is enabled or modified
from a Wirepath™ NVR.
Video Frame
Higher FPS (Frames Per Second) provides a smoother image, however some display
Rate
interfaces or devices may not be able to support the higher frame rates.
The available frame rates change based on the number of streams:
Recommendation: We recommend using the default FPS unless problems
displaying video occur.
