That isn't needed, anyone who cares to can figure that part out. Cameras are cheap enough to put them up and leave them, and you can figure occupancy in many ways. Breaking into your house to place hidden cameras would not be hard - I don't know anything about where you live or your house, but I can confidently say I could get in if I wanted to. (lock picks are not hard to get, and it only takes a few days of observation to figure out when you leave)
