Example of usage EloquentEsp32cam library.

For example, you want to monitor activity behind a glass window and, if motion is detected, take a screenshot and send it over the network to a telegram bot.

The first solution that comes to mind is to use a PIR sensor. But this solution will not work, because... glass reflects ultraviolet and most infrared light.

In the working solution, the PID sensor is excluded from the circuit. The camera takes pictures at a certain frequency and compares them with each other, if the comparison algorithm considers that the discrepancies between the frames are significant, the motion trigger is triggered.
