If you still do not know MotionEyeOS, you have been deceived. It is a small wonder since it allows you to transform a Raspberry Pi into a complete home security camera system. It is also a very active project that offers many possibilities. You can use the Raspberry Pi camera, but it also supports USB cameras, motion detection, timelapse function or even uploading files to the Cloud or email notifications. It is not an application, but a complete Linux-based operating system of course, which is simply loaded onto the memory card and in just over 30 minutes you have it working. Through a web environment, you can configure various aspects of MotionEyeOS. In the video that I leave you below, an example with the little raspberry Pi Zero Wifi.
