Smart IoT endpoints

So far, we have examined very simple sensors that simply return information in a binary or analog form that must be sampled. There are, however, IoT devices and sensors that have substantial processing power and performance for the tasks they undertake. Smart sensors include devices such as video cameras and vision systems. Smart sensors can include substantial amounts of processing in the form of high-end processors, digital signal processors, FPGAs, and custom ASICs. In this section, we will explore the details of one form of smart sensor: a vision system.
