In SafeFac a set of cameras installed on the assembly line are used to captu. There are two ways in which smart record events can be generated - either through local events or through cloud messages. Smart video record is used for event (local or cloud) based recording of original data feed. My DeepStream performance is lower than expected. It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. My DeepStream performance is lower than expected. I started the record with a set duration.
