This trigger component processes frames (in constant intervals) at a given frame rate.
This component should be used with all cameras that do not implement a trigger mechanism. If the camera is triggered by another mechanism, no timer trigger should be used, as these two would interfere with each other.
An timer firing at regular intervals releases the veto. Hence, this component guarantees that no more than 1/interval frames are processed per second.
The interval at which trigger events are generated.
