Indeed, I was thinking about putting 3 camera's on each side of the house to get as much coverage as possible.
Thanks! There are various 40W lights in the yard so it isn't pitch dark. But the camera's need to be good at night. The fence is very high in the back and side so I don't really think someone can easily jump over the fence. I think a general overview of the yard is fine, except for the front where I would like to have an overview of the street as well. I think the problem with the yard is that it's wide. Placement is indeed another problem. I though about placing them evenly along the house. No, not that easy as that?
Thanks! Great tips about placement. Indeed, visible cameras are a deterrent (ususally). I'm not really a fan of IR. Do the IR lights last a lifetime since they're on all night?
