Axis Zipstream technology reduces bandwidth and storage usage. You can configure your Axis cameras in Security Center to take advantage of Zipstream technology.

What you should know

Your Axis camera must support Zipstream technology and be running the appropriate firmware:
  • Firmware 6.30 or later is required for Zipstream with dynamic frame rate.


  1. From the Video task in Config Tool, select the camera to configure.
  2. Click the Video tab.
  3. Select a video stream tab at the bottom of the Video tab.
  4. In the Video quality section, set the Bitrate reduction strength value.
    This value determines how much the video outside a region of interest will be compressed to reduce bitrate and save bandwidth. For example, if you are surveying a park that is surrounded by office buildings, the video footage of the surrounding office buildings will have a lower bitrate to save on bandwidth.
  5. (Optional) Enable Dynamic GOP (Group of Pictures) and set the Max length.
    The Dynamic GOP adjusts the number of P-frames that are sent to the Archiver between two I-frames. Since the adjustments are based on the amount of motion that occurs, the GOP length varies. Use the Max length value to set the maximum amount of P-frames that will be sent. The higher the Max length value, the lower the bitrate, which saves bandwidth.
  6. (Optional) Enable Dynamic FPS to have the frame rate dynamically adjust based on motion. When there is little or no motion, the frame rate drops automatically.
    NOTE: This setting is only available for H.264 streams on units that support Zipstream with dynamic frame rate.
