If User performs search, fast forward, rewind or search by frame – each camera will be synchronized.
However, recording may be set up differently. If no recording took place over a certain period of time, NO DATA will
appear on the camera view.
Recorded fragments are displayed on the Time Line in two rows:
 The upper row displays fragments for Camera selected on Scene
 The lower row – for all Cameras displayed on Scene
It is possible to disable Synchronization (press SYNC button). If no Item is selected, the selection will move to the
previously selected item, which will become the only item affected by playback controls (seek, speed etc).
Thus, if Synchronization is disabled, it is possible to seek each Camera in a different position. In this case Time Line
displays positions for all Cameras played back (see blue markers on the picture):
If User selects Camera on Scene and enables Synchronization again, all other cameras will get synchronized with the
selected Camera (Position and Speed will be synchronized).
Configuring Live Buffer Size
On some cameras Live playback may stutter or there may be significant delays between actual action and action
shown on Live view.
In this case it is necessary to adjust live buffer size. To do so, open Main Menu, choose Advanced, then adjust
Maximum Live Buffer Length:
 bigger buffer makes playback smoother but increases the delay between real situation and live view,
 bigger buffer can cause stutters on playback but decreases the delay.
Adjust the value to smallest possible one without issues on live view on all cameras for better viewing experience.
