Figure 55. Viewing Archived Video
NOTES:
• If you attempt to load archived video from a date/time and camera for which no archived video exists, “No Video Found” appears in the cus-
tom window control bar.
• DX9000 DVRs overwrite old archives when they run out of recording space. If you try to view old video that has been overwritten, “No
Video Found” appears in the custom window’s control bar. Note that VMX300(-E) does not delete archived alarms and events when the
DX9000 DVR overwrites the video. Archived alarms and events for the selected date/time still exist, even though the video for that date/
time has been overwritten.
• DX9000 DVRs can be configured to start recording when motion is detected, according to a schedule, or in response to a device-internal
alarm.
If you attempt to load archived video and it fails because no video was found, it could be for the following reasons:
• The DVR is configured to record when motion is detected. No motion was detected on the switched camera at the date/time you selected
in the Event Picker, so the DVR was not recording at that time.
• The DVR is configured to record at scheduled times. The DVR was not scheduled to be recording video from the switched camera at the
date/time you selected in the Event Picker.
• The DVR is configured to record when a DVR-internal alarm is triggered. No alarm was triggered, so the DVR was not recording video from
the switched camera at the selected date/time.
TIPS:
• If you know which camera the desired video originated from, you can switch the camera to the custom window before selecting a
date/time in the Event Picker. If the camera is already switched to the window, you do not need to switch it again. If you do not know
which camera the video originated from, first select the date/time, then switch different cameras to the window successively until
you find the one you want.
• If your installation has multiple cameras and you have more than one custom window to view video in, you can play back synchro-
nized archived video from several cameras simultaneously. Drag a different camera to each custom window and select the desired
date/time in each window’s Event Picker. There will be a delay between windows equivalent to the length of time it took you to drag
the next camera to its window.
• You can track a moving object, such as a person or vehicle, in a single custom window by successively dragging adjacent cameras to
the window. Suppose the object moves across the range of Camera 1 to within the range of Camera 2. First, set the cursor mode to
Synchronized, as described in Controlling a DX9000 DVR - Playing Archived Video. Now, drag Camera 1 to the window and start the
video playing at the desired time. When the object leaves the range of Camera 1, drag Camera 2 to the window. The video from
Camera 2 will automatically cue to the Event Picker time, which is synchronized with the playback time, picking up where the
Camera 1 video left off.
