It is possible to quick-circuit the filter pipeline at any level by setting the Result house around the context parameter provided for the filter process. As an illustration, the subsequent ShortCircuitingResourceFilter will avoid another filters from operating later while in the pipeline, together with any motion filters.

If we set several filters for a similar action, they can cause redundancy leading to unpredictable actions and unneeded stability hazards.

We will configure filters globally in the Program class.
