Condensation issues Ring doorbell 2

Hi all,I realise there are already a few topic responses on here to condensation. But mine does not involve condensation inside the doorbell. I have recently moved to a very rural part of Essex amongst fields. Unfortunately this winter has caused the dampness from the surrounding countryside to fog up the glass over the camera lens on the outside.I have thought about buying a silicone cover for the doorbell casing or indeed something similar but I do not think this will resolve the issue. The condensation will just build up on whatever serfice is exposed.I have been advised to buy some of the product that is used to defog / keep clear motorcycle helmet visors.such as Rain-ex. Can I have your opinions / help please? Even now at 10.50am the live view is covered in wetness.Many thanksPaul
