Camera constantly goes off with no motion. You will not remedy the problem.

You haven't provided any details for us to work with. WHat have you tried? What do you see? What mode are you using? Have you changed motion sensitivity? Have you removed and resynced the camera?

Updated firmware.
Still repeatedly taking pictures of nothing. Other 3 cameras work fine.
Why wont you replace the 1 defective camera i purchased?

While it's just a guess, I'd wager it's the sun's IR being reflected that's causing the issue. Does it happen mostly at certain times of the day and maybe not at night? Since you didn't answer any of my previous questions, they still stand but I would also start with reducing the motion sensitivity in your modes and rules. You may want to create a custom mode with reduced sensitivity for the time(s) when you're most likely to get false triggers and then use the schedule to automate switching between high and lower sensitivity modes.

What are your previous questions?
