Video Bitrate
Advanced Mode Only:
Sets the fixed bitrate to use when CBR is selected for bitrate control. While many
intermediate settings exist, recommend setting to 1, 2, 4, 6 or 8 Mbps for compatibility
with
Wirepath™ NVRs.
Note: This setting will be selected whenever the camera is enabled or modified
from a
Wirepath™ NVR.
Video Frame
Rate Higher FPS (Frames Per Second) provides a smoother image, however some display
interfaces or devices may not be able to support the higher frame rates. Adjusts the
bitrate from 5 FPS to 30 FPS for streaming 1, and from 5FPS to 15FPS for Streaming
2.
Recommendation: We recommend using the default of 30 FPS (Streaming 1) and
15 FPS (Streaming 2) unless problems displaying video occur.
GOP Size GOP (Group of Pictures) is successive picture that is used to generate the visible
frames of a video stream. The GOP size setting determines the multiplier to use for
producing intermediate frames based on a standard of 15fps.
Example:
1/2xFPS =7.5fps
1xFPS
=15fps
2xFPS =30fps
Note: Changing this setting will affect the performance of the stream. The highest
setting (2XFPS) may result in saved video playback issues when Video Format is
MPEG4 or MJPEG. We recommend that this setting is left at the default setting.
Video Format While the default of H.264 is most efficient and will work in most cases; some devices
that access Streaming 1 or Streaming 2 video streams may not support this format.
For example, mobile devices, and automation system GUIs sometimes do not support
H.264. Adjust the format to suit the system requirements and intended use of the
streams.
