Face recognition problem

#1

Hello, Im currently in 5th grade so please dont expect much. I am working on a project for school that requires technology. My plan was to make an alarm when some unrecognized person enters something. I trained the models for the recognized person. But I cant make it recognize human feature without the training model so it will turn an alarm. And sometimes it would not recognize the right thing. If anyone could help, I would really appreciate it

Hey, @JustAle, let me clarify some things:
You are using mBlock 5 and the Teachable Machine extension on a sprite; and your device that you are running mBlock software on has a camera that mBlock can access. Correct?
