The Tapo C225 camera has a tilt function that allows the camera to be rotated vertically. The tilt range of the camera is 60° mechanically, which corresponds to an effective tilt coverage of 149°.

You can therefore set the camera to look downwards, but it cannot film down to the floor directly in front of the window sill if it is placed on the window sill. However, the camera can be pointed downwards to a certain angle to monitor the area below the window sill, but it depends on the specific position and height of the window sill how much of the floor area it can actually cover.
