CONFIGURING VIDEO LOSS DETECTION
You can configure the DX8100 to monitor each camera for the following events:
•Loss of synchronization: This event occurs if the data cable between the camera and DX8100 is disconnected (cable is cut or unplugged) or when the camera looses power.
•Low level of video: This event occurs if the DX8100 detects a low level of video signal from the camera:
–The available light source for the camera (indoor/outdoor lightly) is greatly diminished.
–The DX8100 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 DX8100 also stores a video incident as a video loss recovery event. The status provides the start and restore time for the video loss event.
The DX8100 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 DX8100 can be configured to use emergency agent notification. In this case, the last available video image at the time the event occurred is sent to the designated remote client. If no image exist, then the system attaches a red colored pane to the

•The record icon turns purple indicating a video loss recording, regardless of the schedule. The video loss utility is constantly running in the background. If a schedule is not available, the record icon defaults to purple. If the DX8100 loses feed, video on that channel is recorded.
