Compression and Image Rate

Use the camera Compression and Image Rate dialog box to modify the camera's frame rate and image quality settings for sending image data over the network.

NOTE: The dialog box may appear differently depending on the device. Options that are not supported by the device will be disabled or hidden.

  1. In the camera Setup tab, click .

    The Compression and Image Rate dialog box is displayed.

    The Total Camera Bandwidth: area gives an estimate of the bandwidth used by the camera with the current settings. Adjust the settings as required.

    NOTE: For cameras capable of maintaining multiple streams, the settings in this dialog box only affect the primary stream.

  2. In the Format: drop down list, select the preferred streaming format.
  3. In the Image Rate: bar, move the slider to select the number of images per second (ips) you want the camera to stream over the network.

    For H.264 cameras and encoders, the image rate setting must be divisible by the maximum image rate. If you set the slider between two image rate settings, the application will round to the closest whole number.

  4. In the Image Quality: drop down list, select an image quality setting. An image quality setting of 1 will produce the highest quality video and require the most bandwidth. The default setting is 6.
  5. In the Max Bit Rate: field, select the maximum bandwidth the camera can use in kilobits per second (kbps).
  6. In the Resolution: drop down list, select the preferred image resolution.
  7. In the Keyframe Interval: drop down list, enter the preferred number of frames between each keyframe.

    To help you determine how frequently keyframes are recorded, the Keyframe Period: area tells you the amount of time that passes between each recorded keyframe.

    It is recommended that you have at least one keyframe per second.

  8. If your camera supports multiple video streams, you can select the Enable Low Bandwidth Stream check box. Depending on your version of the software, the check box may also be called "Enable secondary stream".

    When enabled, the lower resolution video stream is used by the Avigilon HDSM™ feature to enhance bandwidth and storage efficiencies.

  9. Click Apply to Devices… to apply the same settings to other cameras of the same model.

  10. Click OK.
