Once the camera receives the start acquisition command, if working in video streaming mode, it will immediately start exposure and output images; if working in trigger mode, it will enter the state of waiting for the trigger signal. At the same time, the camera enters the '''''running state'''''.

−Once the camera receives the stop capture command, it will complete the currently transmitting frames to ensure frame integrity, and then stop outputting images and enter the '''''standby state'''''. Note that the triggering process will be interrupted if triggering multiple frames is set and not all image frames have been output yet.

Note that the triggering process will be interrupted if triggering multiple frames is set and not all image frames have been output yet. That is, stopping the acquisition operation only guarantees the integrity of the current frame, not the entire trigger cycle.

==== Switching of modes ====
The working mode cannot be switched during operation; you must stop the acquisition before switch to a new working mode.

+==== Trigger source ====
+The soft trigger and hard trigger are only different in the source of trigger signal. The trigger delay, exposure delay, trigger frame number, trigger interval configurations and functions are exactly the same.

+===== Software trigger mode =====
+By writing 1 to the corresponding register of the camera via the i2c bus, a soft trigger is performed.
+
+Since there is a certain delay in software processing and i2c transmission, the timeliness of soft trigger is worse than hard trigger , and hard trigger is recommended for the occasions with high timeliness requirements.
