Live camera to monitor patio that I can see on my cell phone, which when it sees movement starts recording

[julianorodrigues0316]

Hello Guys, I'm new here on the forum, so I don't know if I'm on the right topic!

I bought my ESP32-cam and it will arrive in a few days. I need help.
I want to make it monitor my patio, that I can see "live" through the camera if I want, but that if
someone enters the courtyard, it is filmed by the camera. That is, the camera only starts recording on the sd, if someone
enter the courtyard. Do you have any code like this or similar, or where do I find it?

Thank you.
Julian
