How to send signal one network to other network device?

Projects General Guidance

Hello everyone. I have a project. In this project, I want to open my door lock from my workspace. In my project i want to use esp32-cam module. I want to do face recognition function in this project. that's right, I do it from the phone, the door opens automatically when the face is recognized, and when a guest arrives, I can open the door through the phone by looking at the guest entering from the phone, but the esp32 cam module requires that the phone and the device are connected to the same wifi. I want to further develop this project and open the door from my workplace. How can I do this? With what device? I'll just do the programming of the guide. I don't know what device I can use. Thank you in advance. Regards, Farhad

start by running Examples>ESP32>Camera>CameraWebServer to get some idea of programming and operating the device
the CameraWebServer sets up a web page which display camera information and you can connect too using a PC, laptop, smartphone etc
then try a web search for ESP32-CAM face recognition

you now wish to be able to connect to the ESP32-CAN from the internet?
if so set up your WiFi router to port forward external TCP requests, e.g. on port 80, to the ESP32-CAM Ilocal IP address

How does it require this? Is it because your ESP32 has a non-routable address (192.168.x.x or 10.x.x.x)?
