To have a more modular project, we have to split our routine into detector and publisher, which are similar to a producer (the detector) consumer (the publisher) pattern.

The publisher itself consist different kinds of publisher such as video stream, mqtt publisher and SystemIO Publisher. For the communication between those two Threads a blocking queue is needed.
