The Internet of Things (IoT) Cloud is currently moving down from the server farms to the Gateway to do computing at the edge. The amount of data generated by sensors every second is staggering, filtering that data at the edge before it goes to the cloud can reduce some of the noise, be more reliable, and keep information more secure. For example, autonomous cars cannot rely on the cloud to do the bulk of their processing. If communication between the car and the cloud is interrupted for a few seconds, it can cause an accident. Consequently, most of the autonomous driving logic processing needs to be done at the edge. In addition, some information being sent to the cloud could be sensitive or private information. Keeping that information at the edge instead of sending it up to the cloud shortens the transfer chain and gives hackers fewer opportunities to intercept the data. This article will explore counting people at the edge without the cloud. Counting people entering and leaving can be useful for retail stores, security monitoring, and a variety of other purposes.
