Triggers an image acquisition on one or more cameras. All cameras will be triggered according to their respective TriggerMode. Hardware triggered cameras will be armed to wait for the next hardware trigger signal. Software triggered cameras will be triggered to start the next exposure


Please also have a look at the Capture command which performs Trigger and Retrieve operations together.

Camera Order

If the Cameras parameter was not specified, the trigger operation executes

  • first on hardware triggered cameras (in any order)

  • then on software triggered cameras (in any order)

If you specified the Cameras parameter triggering will execute sequentially on the cameras exactly as specified in the Cameras array (starting from index 0).


Software triggering of GigE cameras will be delayed until the LED can flash for the full exposure time without leaving its specification. See the Illumination (GigE) topic for details.
