VIDEO LOSS ACTION
This option is used to specify what is to happen in the event of loss of a video input. Video loss can
occur due to a failed camera or disconnection of the video signal to the multiplexer.
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:
Monitor-B 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.
Indication:
On-screen display of text
"V"
in each affected cameo of the multi-screen display and
‘VDL’
on any
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. Select the camera for setup, then select
either ENABLE or DISABLE for each relay (relay-1 and relay-2) and ENABLE or DISABLE for the
Buzzer.
