Triggering a Capture
~~~~~~~~~~~~~~~~~~~~

Captures can be triggered remotely through the CameraSDK, using the following method:

.. code-tabs::

    .. include-tab:: ../../labels/cppTriggerCapture
        :language: cpp
        :title: C++

    .. include-tab:: ../../labels/cppTriggerCapture
        :language: csharp
        :title: C#

.. caution:: This method works only if the camera is "*ready for capture*". E.g., the camera needs to have either a memory card accessible to the camera, or be set-up to send the captures to the :term:`Host computer` (see :ref:`camera-receive-images-label`).

Caveat
^^^^^^

These "*trigger capture*" messages are sent to the camera, over the connection you have set up (USB or TCP/IP). The nature of USB and TCP/IP implies some amount of latency. And worse, jitter!

Therefore, the API for *capture triggering* is useful for development scenarios - not for real world applications. In production you would likely want *very* tight control of camera triggering. This is beyond what is possible over TCP/IP and USB.

.. hint:: In production setups, you could use our `iXLink <https://www.phaseone.com/wp-content/uploads/2021/10/iX-Link-Protocol-Programming-Guide.pdf>`_ protocol, to do remote triggering of cameras. (iXM cameras series only.)
