Dusk to Dawn failure

Having issues with the dusk to dawn setting failing almost weekly. I have talked to support, received new floodlight camera and it did it again last night. It works at the dusk time, but at some point through the night, it fails. I can manually turn on the light, but this is a security issue where me as a homeowner, wants light on ALL night. Any others experiencing this with a correction? I am thinking its a software glitch.
