I know right... My neighbour opposite got a doorcam last summer, (on her front door) after we had had a strange man wandering about in the area who was trying side doors and back doors, and also trying car doors. It faced my front garden and driveway and house, and whenever I was in the garden weeding and planting and digging, and cleaning the car, and tootling around at the side of the house, going in and out of the garage and so on, I was acutely aware that the camera was on me. No matter where I was in the garden, the camera was looking at me LOL.
I became so self conscious, especially when one of the kids told me their mum was watching them on the drive from work on her break, and they said that she could see them on the lawn of the people who live next door (to me) when they were playing on the front lawn with the little girl who lives there. The camera had quite a wide view on it. I thought 'if she can see them, and watches through the webcam when she's at work/not at home, she could be watching me too.' Or 'the whole family could be sitting there watching me and laughing at me.' And they have footage too, so I was effectively being filmed.
May sound like I'm paranoid, and I know I probably am a bit, but I HATED that bloody camera being there pointing at me, watching me, my every move, everything I did...
Fortunately, it broke around March this year, and they never bothered getting it fixed or replacing it.
I really dislike cameras being everywhere, and especially when one (that belongs to someone else,) is poking its face into my house, garden, garage, driveway, lounge window, front doorstep, etc.... and I don't have any control over the footage.
They are handy for security, but the invasion of privacy (when they are on the front - or back - of people houses,) is a massive drawback.
