-The platform will automatically add all sensors to Home Assistant that are configured within the camera interface to "Notify the surveillance center" as a trigger.  If you would like to hide a sensor type you can do so by either unchecking "Notify the surveillance center" in the camera configuration or by using the "ignored" customize option detailed below.
