Moin, we had the camera for observing our house building used. One has to try a few times until you get the optimum angle or height. This must not be underestimated. Final, we have the camera mounted from Diebstahlgünden in a bird house and hung on a higher tree. After shell or roof were done, we have not used. Then usually happens very little, as the interior work begins. Let's see, we used to hire them again when the outdoor arise.
