Where is the best place to mount window?

So window can distinguish, as reliable as possible, whether or not a window is open, closed or tilted, mount it in the upper corner, on the side with the window handle (see illustration below). For window to be attached securely, please use the adhesive strips, which are included in the set. This is very important, because the sensor must be moved by at least 5 degrees to recognize whether a window is "tilted".
