I just find it funnier that they have to ring the bell. Human nature to press the button.
Also thinking about it I have a doorbell like that and it rings every time a bird flies past. It is supposed to not detect birds, leaves and people driving past on the road, it's supposed to only detect humans but it 100% doesn't work. I can totally see something like this malfunctioning and just going off because a leaf got blown past it.
Its a wireless camera door bell, called "ring".
No idea if this is real but i assume you could set something like this up to be either motion detection activated(like a mine) or remote activated by looking at the camera feed.
One time I went to Egypt and there was just a random ass power outlet on a rock in the desert. To this day I have no idea why it was there or if it was connected to anything
