im wondering if you can help me i have the DS-2CD2135FWD and im unable to remove the "max size" setting in the smart event option, i press clear it disappears then i press " save " but when i come off the selected page and return back to the smart event page its back there again. I tried the factory reset using the hikvision page in safari and its still there and as a result the smart event is not picking anything up , only the " motion settings " pick up movement and that picks up everything including the wind lol which is a pain. do you have any suggestions?
