The Smart Compression level allows you additional control to balance video quality versus bit rate.
The smart compression settings determine how aggressively the camera will drop the bit rate on
easily compressed scenes and how aggressively it will adjust image processing settings to make
the scene more compressible. If the scene is difficult to compress (high motion, high noise), the
camera will use the full bit rate allowed by the stream bit rate settings. The “off” and “low” settings
will have a similar, minor effect on the image; the “medium” and “high” settings will have
correspondingly more effect on the image and greater savings on storage.
l Off—no bitrate reduction
l Low—no visible effect on video quality in most scenes
l Medium—visible effect onf video quality in some scenes
l High—video degraded in many scenes
3. (Optional) Enable Dynamic GoP Length. If you want to place an upper limit on the Dynamic GoP
length, set the Optimal Maximum GoP Length for each stream.
Note
: The option to establish the Dynamic GoP Length is enabled when compression levels
are set to Low, Medium, or High.
4. (Optional) Set the maximum GoP length for your streams if you want to impose an upper limit on the
dynamic GoP setting.
By enabling a dynamic Group of Pictures (GoP), the number of I-frames are automatically reduced in
scenes with minimal motion. Based on the complexity of scenes and the amount of motion
occurring, such as in a storage room that has limited activity, up to 70% bandwidth savings can be
achieved.
Dynamic GOP allows the camera to update picture groups depending on scene composition and
motion. A dynamic GoP can further reduce bit rates produced by the camera by allowing the camera
to increase the GOP length when there is little action in the scene.
For each video stream, you can enable Dynamic GoP Length as well as establish an Optional
Maximum GoP Length. GoP length will change dynamically based on variable conditions that your
camera might be monitoring.
Note: Dynamic or long GoP lengths may cause compatibility issues with some video
management systems (VMS). Ensure your VMS supports dynamic GoP settings before
enabling this setting.
Configuring Long-Term Rate Control
Set Long-Term Rate Control if you must ensure storage does not exceed a specific size.
1. After ensuring the date and time have been set on the camera, run the camera for multiple days
which should represent multiple times the length of the observation period you will be using.
2. On the Pelco Smart Compression page, click Long-Tem Rate Control.
3. Select the Video Stream to which you will apply the settings.
4. Select the Bitrate Units: either total kbps or Gbytes/day.
5. In the Long-Term Rate Controls area:
