Ah I think I see what your saying. Perhaps I am being a bit too ambitious of what one camera (the bullet type) can actually cover from that location. It probably doesn't help you can't really see my whole setup so hopefully the pictures below will assist.
And just to confirm, for now, my main objective is just to deter anyone trying to break in to my house. The TIOC camera having that loud alarm when a human is detected looks ideal for this! I am not worried about having full coverage of my garden and I am keen not to cover my neighbors garden at all as I do not want to invade their privacy (they have a small child).
My original thought was to have 1 dahua TIOC bullet camera facing roughly this direction (blue arrow) to view the majority of the back of the house. Specifically; the patio door, single downstairs loo window at the back of the garage, and maybe the kitchen window next to the AC unit (but that might be out of view thinking about it).
The rest of the garden at this point would not be covered, so potentially someone could sneak down by my fence on the right if they were able to get in to the garden further up.
My future plan was to potentially put another camera, bolted a bit higher up on the fence post marked on the picture below with the blue cross (they have holes through them so can easily bolt a piece of timber to it). The camera could either point towards the gate (blue arrow), or towards my bin store.
People can potentially climb over that brick wall (it's only about 6 foot high on the other side where the cars are).
One last thing I should mention, there is a street light in between the two cars in the picture below. It lights up my whole garden normally, but it's been out of action for about a year. We are having trouble with the estate management co to get it sorted.
Is there a fish eye camera that has the same features as the dahua TIOC (i,e the alarm)? If so that would probably be best suited in the middle of the property, one out the front, one out the back.
