I installed Google nest cameras around my house, including their doorbell camera, in early January. Similar to RING and others. I chose Google just because we have other products from them and they had a good sale going.
Not long after the install we went to dinner early. The place is close by in our neighborhood. My alert dings 5 minutes after sitting down. A person is seen at the door.
This guy and some buddies had approached the front door. As soon as he saw the camera he said RING to his buddies and they booked.
If I had any doubts about the effectiveness of cameras and good exterior lighting, they are long gone.
