Synchronous Playback
4-channel synchronous playback function allows user to review what happened at a give time
from four different cameras. Synchronized playback works by first finding the time you wish to
investigate from a
“Sync Main” channel. Then you may add up to three other reference
channels that will synchronize with the Sync Main channel. These other channels are called
Sync Follower.
Open file/Drag-drop channel
There are two ways to start a sync playback, first you need to define a
“sync main”
for other
channels to sync with.
1. Drag: You may drag a channel into one of the 4-window view or
2. Open: You can open a file from archive to sync with
Note: You may sync to a maximum of 4-channels at one time.
