I was thinking of applying silicon around the base of my doorbell mount, not where the doorbell attaches to the mount. Is this something people do?
Also I think I need to do something around where the DC cable connects with the extension. It becomes loose easily and by the way it will sit inside the gap I am concerned it will get water into it. Would a heat shrink tubing work or some good old teflon tape with electric tape on top of it?
