The amount of light entering the camera has fallen below the allowed scene loss intensity level configured in the Digital Sentry software.


If the reason for the dark picture is known, for example a light being turned off in a room or an outdoor camera with poor night lighting, change the "Loss of scene intensity range:" in DS Admin to a lower intensity value.

Analog Cameras

  1. Open the DS Admin utility on the DS recorder (Start > All Programs > Pelco > DS Admin).
  2. Login with the 'admin' user account or another user account with configuration privileges.
  3. Expand the "Cameras" folder and click on the effected camera.
  4. Under the General tab, move the Loss of scene intensity range: slider to the left.  This will lower the sensitivity and require more a darker environment to trigger the video loss / scene loss. 

    Move the slider to a value of (1) to stop all scene loss detection.

  5. Once the value has been changed, click on Save to save the changes.

Apply to all cameras:

  1. You can adjust this value and save globally to all cameras by click on the either the "Cameras" or "Analog H264 Cameras" folder and using the Apply to all cameras in folder button.  Beware that other settings listed in the General tab will also be applied to all cameras, like the record rates for analog cameras.


IP Cameras:

  1. IP Cameras do not have the Loss of scene intensity range option in the General tab on an individual camera basis, you must use the Global option above in order to set the scene loss for IP cameras.  Click on the Cameras folder and adjust for all IP cameras.
