I just installed my floodcam on Saturday and had the same problem, lights would not turn off. I followed the instructions mentioned in this forum including the covering sensor with black electrical tape. The lights turn off after completing the steps, but then came back on after a minute or so. I followed the steps once again and the lights came back on after a minute. I then turned off the power from the floodcam, then adjusted the cam to the dark setting. I turned the power to the floodcam back on and then remotely turned the lights off. From that point, the lights stayed off. At night, it came on only when motion was detected and turn off one minute later. Just like it was suppose too. Today Monday, it still works fine. Off during the daylight hours and on when motion during the dark hours. Don't know what really made it work, but just wanted to let you guys know what worked for me. It probally was just coincident. But it works and I won't touch it again for right now. I think these procedures work best during daylight hours.
