I follow your ESP32-CAM video streaming and face recognition with Arduino IDE article.
After a lot of trouble, I succeeded to upload the code to the ESP32, but opening the serial monitor I don’t see the IP address as described in your manual.
This is what is written in the serial monitor:

I disconnected the ground and pushed the rst button on the module. It scrolls this text over and over again.
Do you have any idea what is happening. The SSID and password are correct in the code.
Thank you in advance.

When you get that error, sometimes you need to reset the ESP32 several times, and then try to upload the code again (sometimes doing just that solves the problem).
It can also be some sort of hardware issue like:
- Poor quality USB cable;
- USB cable is too long;
- Board with some defect (bad solder joints);
- Bad computer USB port;
- Or not enough power provided by the computer USB port.
Which FTDI programmer are you using to connect your board? Some readers reported similar errors when using the CH340 model.
Also, try powering the ESP32-CAM with 5V and see if that solves the problem.
I hope this helps.
