What is ESP32 cam?
ESP32-CAM is an embedded module which can be used to stream video data by constructing a local server. The module can be programmed using the Arduino IDE. We usually access ESP32-CAM Video Streaming using the IP address through the local area network. What if you want to access your WebCamServer from anywhere in the world? You must be asking yourself either it is possible or not to access the webserver from any location in the world using the same IP address. So the answer is yes we can access it using a third party service which will route ESP32-CAM IP address from local area network to be accessible anywhere over the internet.

Can you connect to a camera without Nabto?
You can connect to the camera on the local area network (not a big deal, you could this as well without Nabto). However, more importantly, you should now be able to disable WI-FI on your mobile device and access the camera using your cellular data (or connect to the internet via another WI-FI). If it would be of help, you can see the process in the video below.
Can a web server forwarded to the camera?
On both sides, all received data will be forwarded to the other side. This makes it seem to the client like the web server on the camera side is running on the app side, since a get request will be forwarded to the camera side and the camera response will be forwarded to the app side. This way you can use a standard app webview to connect to the web server on the camera (using the tunnel to remotely forward the data).

How many times does the ESP32 camera blink?
The ESP32-Cam's LED will blink once when the camera is initialized correctly, and then twice when WiFi is connected. It will blink 3 times if camera initialization fails, and then reboot. (This happened to me sporadically.)
How to tell if ESP32 battery is charging?
To detect when the battery is charging, there is a connection from the PowerBoost's USB pin to an input pin on the ESP 32. When the input pin reads HIGH, the web page will say "Charging" on the bottom left. I would have expected this pin to be at 0V when not charging, but for some reason there is a small voltage, roughly 1.0 to 1.7V, which is enough to register as HIGH. So the variable potentiometer divides this voltage to a lower level that registers as LOW on the input pin. To calibrate this, rotate the potentiometer to a point where the web page will say "Charging" when a USB power cable is plugged into the PowerBoost, and not say "Charging" when not plugged in.
What happens when the ESP32 boots?
When the ESP32 boots, the left motor turns on (reverse) for a fraction of a second, which can be bad if the robot is on a desk or nearby something. I tried various solutions but was unable to fix this, so if anyone verifies a solution, let me know...

Why does my ESP32-Cam say "Brownout trigger detected"?
If your ESP32-Cam often says "Brownout trigger detected" on boot, it could be caused by any number of power-related problems. For me, it was poor wire connections on the breadboard.
Can robots access the internet?
Accessing from the internet. By default, the robot's web page is only accessible from your local network. To access it from a remote location over the internet, you will need to set up a VPN to tunnel into your local network.
Introduction
Creating a locally accessible camera application with the ESP32 is something that has already been done. But why do you need a camera that you only can access on your local network? You can just go look at the thing that the camera is capturing instead of looking at it on your computer or app (unless you have a very big house).
