1. A system for monitoring a plurality of process stations, the system comprising:
one or more cameras configured to capture digital images of the plurality of process stations; and
at least one processor configured to:
identify a sequence of digital images of a process station of the plurality of process stations generated by the one or more cameras during an operation of the process station;
identify, in the sequence of digital images, a visual indicator of the process station based on a quick response (QR) code arranged proximate to the visual indicator, the visual indicator comprising a measurement displayed by an instrument of the process station;
analyze the visual indicator in the sequence of digital images to identify a current rate of change of measurements displayed by the instrument;
identify, using the QR code, configuration data for the process station that defines an expected rate of change of the measurements;
determine whether the current rate of change deviates from the expected rate of change; and
generate indicia representing the identified current rate of change in response to determining that the current rate of change deviates from the expected rate of change.
