CONFIGURING VIDEO LOSS DETECTION
You can configure the DX8000 to monitor each camera for the following events:
• Loss of synchronization: This event occurs if the data cable between the camera and DX8000 is disconnected (cable is cut or unplugged)
or the camera looses power.
• Low level of video: This event occurs if the DX8000 detects a low level of video signal from the camera:
– The available light source for the camera (indoor/outdoor lightly) is greatly diminished.
– The DX8000 data cable is disconnected.
You can adjust the operation time from 0:00 to 23:59. For example, if the start time is 6:00 and the end time is 18:00, a low video level event
from 18:01 to 5:59 will not be detected. The low video level detection time option is only available when the low level of video option is
selected.
The DX8000 allows you to select the loss of synchronization and low level of video option independently.
• The PTZ camera and multiple relay output can be mapped to a video loss event.
• Multiple cameras can be configured to record in response to a video loss event.
• The DX8000 can be configured to use emergency agent notification. In this case, the last available video image when the event occurred is
sent to the designated remote client. If no image exist, then the system attaches a red colored pane to the e-mail. The red pane contains
the text “Video Loss.” For information about setting up emergency notification, refer to Emergency Notification Setup on page 198.
• The DX8000 can be configured to send an e-mail notification in response to a video loss event. In this case, the last available video image
when the event occurred is attached to the e-mail. If no image exist, then the system attaches a red colored pane to the e-mail. The red
pane contains the text “Video Loss.” For information about setting up emergency notification, refer to Emergency E-Mail Notification Setup
on page 201.
• The record icon turns purple indicating a video loss recording, regardless of which schedule is setup. The video loss utility is constantly
running in the background. If a schedule is not available, then it the record icon defaults to purple. If the DX8000 loses feed, video on that
channel is recorded.
To set up video loss detection:
1. On the DX8000 toolbar, click . The Setup dialog opens to the Camera page.
2. In the Video Loss Detection section, do one or both of the following:
• Click the “Loss of synchronization” check box to select loss of synchronization option.
• Click the “Low level of video” check box to select low level of video option and do the following:
(1) In the Low Level of Video Detection Operation Time section, set the start time.
(2) In the Low Level of Video Detection Operation Time section, set the end time.
3. Click Apply.
