Internet of Things with Raspberry Pi 3

Wiring up

Now, we will wire the hardware component to complete our circuit. Note that in actual scenario of building access management there will be two separate systems, one for adding people to the authentic list where a picture of that person is taken for the first time and stored for matching purposes in future. In the other systems when a person tries to enter the building, the system will capture the image in real time and then do a comparison with a collection of authentic faces (this collection is created while adding people to the Authentic list for the first time). If the faces match successfully, that means the person is authentic and allowed to enter; otherwise they are not allowed to enter.

So, these two system will have separate ...
