I recently became the head of the house and you gave a good idea. We will also soon need a program that recognizes faces, we want everyone who enters the entrance to be recorded by the camera. I wonder how much programmers will charge for their services, I want to calculate everything in advance. I followed your link, read it, this server interested me, I think that I will contact them, but for now I will bookmark the link, I think it will come in handy soon...
