“In the category of security products, you will see cameras known as ip cameras, which actually deliver the received images to the user through the cloud from anywhere in the world. In this tutorial, we are going to use ESP32-CAM boards and Cloud ngrok to build such a device with the ability to send images to different places without any restrictions. In fact, once the project is completed and launched, you will only be able to access it with a single link.
What is ngrok ?!
ngrok is a cross-platform application that enables developers to expose a local development server to the Internet with minimal effort. This software allows your local web server to be hosted under the ngrok.com domain, meaning that no IP or public domain name is required on the local device. Similar performance can be achieved with Reverse SSH Tunneling, but this requires more configuration as well as hosting from your remote server.
ngrok can circumvent NAT and firewall mapping restrictions by creating a TCP tunnel from a randomly created subdomain at ngrok.com (e.g. 3gf892ks.ngrok.com) to the local machine. After specifying the port that your web server is listening to, the client program starts connecting by connecting the server, and then anyone can request a unique address from their local server.
How the project works
This project works in such a way that by using the ngrok cloud, after registering and receiving the required code and then running the ESP32-CAM web server on the local network with the help of the ngrok cloud, the data is transferred to the cloud and received on the side We will do it again. This process is done using a cmd in your Windows machine, but of course there are other versions for the Linux machine that allow us to use Raspberry Pi to be able to run the server part of the project.”
