Enabling HDSM SmartCodec™ Technology Settings

NOTE: Only available to cameras that support this feature.

HDSM SmartCodec technology operates by separating foreground objects from the background image, then reduces bandwidth by increasing compression to the background image. In this way, higher quality image is retained for objects of interest in the foreground while reducing bandwidth for static backgrounds. When there is no motion in the scene, HDSM SmartCodec feature switches the camera into idle scene mode to increase bandwidth savings when there are no objects of interest.

HDSM SmartCodec feature uses the camera's motion detection area to help define when it should switch to idle scene mode. You can configure the motion detection area from the Motion Detection dialog box. For more information, see Motion Detection.

  1. In the Compression and Image Rate dialog box, select the Enable HDSM SmartCodec check box.

    The HDSM SmartCodec settings are displayed. If the settings do not automatically display, click to reveal the settings.

  2. In the Bandwidth Reduction: drop down list, select one of the following options:
    • Low
    • Medium
    • High
    • Custom

    If the scene background does not provide any valuable information, for example a white hallway, choose High to enhance bandwidth savings. If the scene background may cause objects of interest to behave differently, for example a traffic intersection, choose Low. This setting provides you with some bandwidth savings, while maintaining enough background clarity to see events in full context.

  3. In the On Motion: section, choose the preferred Background Image Quality: option.

    An image quality setting of 1 will produce the highest quality background image but require the most bandwidth.

    When motion activity is detected, the foreground areas of the video are streamed and recorded using the High Bandwidth Stream settings while the background areas use the Background Image Quality: setting.

  4. In the On Idle Scene: section, enter the Post-Motion Delay: setting in seconds. This field defines how long the scene must be idle before it switches to idle scene mode.
  5. In the following Image Rate: bar, move the slider to select the number of images per second (ips) you want the camera to stream while the scene is idle.
  6. In the Image Quality: drop down list, select the video image quality when the camera is in idle scene mode. This setting is applied to the foreground and background image.
  7. In the Max Bit Rate: field, select the maximum bandwidth the camera can use in this mode.
  8. 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.

  9. Click OK to save your settings.
