Face recognition is fore me the most secure way to know who you are. Presence detection using Owntracks or similar show the presence of a known phone, whoever carry it.
I have a security camera setup using Xeoma server. It has a very competent face recognition as one of its modules.
I would like to use it together with HA but have no clue how. There is a component to show the Xeoma cameras in HA but not much more. Has someone worked with this system? One of the good things with Xeoma is that almost every camera out there can be connected, the face recognition is in the server
