Floodlight cam light won't turn off

A friend of mine has the floodlight camera and we recently lost power due to Hurricane Zeta. He has since gotten power back, but not internet therefore he cannot turn off his floodlight. It's been on for the last 2 days. Is there a manual override when something like this happens or does he have to wait until his internet is reconnected to turn it off? If he has to wait, I would suggest some type of manual override to turn off the light. Since we had a major hurricane, we have no idea when internet will be restored.
