For outdoor SharpV installations, to minimize motion blur in the context image, you must adjust the context camera exposure according to the typical speed of traffic being monitored.

Before you begin

What you should know

  • The SharpV context camera exposure is automatically adjusted according to current light levels. In low light conditions when the exposure is long, a fast-moving vehicle that crosses the camera's field of view appears blurry. To reduce the amount of motion blur in the context image, you must reduce the camera's maximum exposure time.
  • In the following example, the entire image is blurry, indicating that the issue is camera focus. For more information, see Calibrating the zoom and focus for SharpV cameras.
  • In the following example, only the vehicle is blurry, indicating that the issue is motion blur due to long camera exposure.

Procedure

  1. Log on to the Sharp Portal.
  2. From the Configuration menu, click Cameras > Exposure.
  3. From the Select your camera menu, select the Context camera.
    The live feed from the context camera is displayed.
  4. From the Exposure drop-down list, select Range (outdoor).
  5. Adjust the maximum Exposure time level according to the typical vehicle speed.
    Tip: The maximum Exposure time is typically the only setting on the Exposure page that needs to be modified from its default value.
