Synchronization 92
3. On the master camera in an EXT sync cluster, you need to define the amount of cameras used in
the cluster. The master camera monitors the connection to each slave camera.
On the master camera, select
MENU > System > Sensor > EXT Sync Camera Count and set the
number of cameras used in your cluster (including the master camera, up to 16 cameras).
4. When using settings slaves, each camera in the setup needs to use an individual camera ID prefix.
Select MENU > Recording > Project Settings > Camera ID Prefix and select an individual prefix for
each camera (usually giving the master camera the camera ID prefix "A")
Media Status with EXT Sync
The master camera calculates the overall remaining recording
time based on the media with the lowest capacity in the cluster.
The overall remaining recording time is displayed prefixed with
EXT on the home screen and in the status info on the master
camera.
EXT Sync Info Screen
The EXT sync info screen displays the system status of all cameras in the EXT sync cluster.
Information on the camera serial numbers, the camera ID prefixes, the battery voltages and the main
status of all cameras are shown.
1. Select
MENU > Info > EXT Sync Info to access the EXT Sync info screen.
Note: The EXT sync info screen lists the cameras sorted after the camera ID prefix.
Note: If one camera in the cluster is not ready to record, the entire cluster will go into idle state. Use the
EXT sync info screen to troubleshoot.
Media Erase in EXT Sync
In EXT sync mode, you can simultaneously erase the cards of all cameras in the cluster:
1. On the master camera, select
MENU > Media > Erase EXT Sync Media .
A confirmation screen is displayed.
2. Press ERASE .
A progress bar indicates the progress of the master camera (only).
3. After erasing has finished, press any button to return to the menu.
EXT Sync Clip Naming
When working in EXT sync mode and the slave cameras are configured as settings slaves, clip naming
is identical to the use of a single camera.
When working in EXT sync mode and using settings sync, the slave cameras inherit the camera ID of
the master camera, so clip file names are identical. To distinguish the clip files from several cameras,
the Camera ID prefix is used. For this reason, each camera must use an individual camera ID prefix.
► Set the camera ID prefix of each camera in
MENU > Recording > Project Settings > Camera ID
Prefix .
Note: The master camera will issue an alert in case duplicate camera ID prefixes are used within
the setup.
Below is a clip name example for a four camera setup, with three clips recorded. The camera ID prefix
is marked in red, the master camera ID is marked in blue. It is recommended to use the same camera
index (green) on all cameras.
