Instance Property


The set of underlying causes for the system pressure level.



Increased system pressure may be due to one or more contributing causes; this set provides additional details for the overall performance characterization reported by the level property.

When the system pressure level is high, you can use this information to choose how to mitigate the issue. For example, high system pressure due to depthModuleTemperature (on a builtInTrueDepthCamera device) can be reduced by throttling the depth capture frame rate.
