If I had a nickel for every Ex-Google, Ex-Amazon, Ex-Microsoft engineer that believes they could be successful in the surveillance/security market by the merits of the technology (i.e. using "AI analytics",) I would be rich. What "they" fail to understand is that it is not a technology problem - it is a sales/marketing problem that deserves more attention. Detecting objects is not solution, it is what you do with it. 100-1000 images for training will not yield an accurate model.
