Use of Ring security camera on window sill to detect intruders outside

I live in a ground floor flat on an estate of low rise blocks in London. We are experiencing a worrying increase with intruders gaining access to our flats and have decided to investigate the use of security cameras. However, the owners of the estate will not permit installing these outside, so we need cameras to be placed on the window sills of ground floor flats always pointing out through the glass. Could a number of 'Ring' cameras do this job? The main problem appears to be during the day as most residents are at home at night. If 'Ring' camereas would be suitable, what subscription would be best for the cloud storage? Thanks
