As we have seen in the previous section, implementing edge analytics into our IoT design has advantages that outweigh the costs and complexity. However, before we can build an edge analytics system, we need to know what the key benefits are.
The following is a list of those benefits (note that these are the same key benefits as described in the Edge computing section):
- Privacy
- Latency
- Reliability
Let's take a look at an example. In the following diagram, we have designed an advanced security application using an edge analytics architecture. As you can see, we have a Raspberry Pi connected to a webcam, automated door, and a light sensor:
Our advanced security application uses the webcam and Raspberry Pi to recognize a visitor trying to gain access to the building. Based on the match of our visitor with a repository of known visitors, our advanced...
