SPECIAL FUNCTIONS
3.6.1
VIDEO LOSS
Indication: LED on front panel, with on-screen display of "V" in each affected cameo of the
multi-screen display and 'VDL' on corresponding full-screen displays. An additional indication in
the form of an LED is provided on the front panel atop the Alarm key. This LED will flash on
and off on video loss detection of any camera input.
Further indication of video loss can be programmed. A relay can be closed whenever video
loss is present, and the buzzer can be activated during video loss.
Video Loss action in Live mode:
Monitor-A: If the camera is being displayed at the time that video loss occurs, the camera
image will be frozen. However, if sequencing is in progress, the display will be
blanked when it is switched to a camera experiencing video loss.
Monitor-B: The Monitor-B display cannot freeze images, and so the display will always be
blanked while a camera with video loss is selected.
Video Loss action in RECORD Mode:
When video loss is detected, the affected camera is temporarily removed from the record list,
and the coded digital data recorded with each field will be updated to indicate a video loss
situation on the affected camera. This video loss status is then shown during Playback. The
SW-D8000U continues to monitor cameras that have video loss and will automatically restore
the cameras when video loss ceases.

Using an 'active cameo' (see Live mode displays), the operator can freeze (or unfreeze) only
one cameo in a multi-screen display. This is useful when an event must be frozen for further
investigation or for review, but the balance of the cameras must continue to be monitored.
