Thanks for answering the questions - that helps a lot. I'm leaning toward a defective camera, which can be replaced using Contact Us. Can you verify the camera has lights on it? And do the lights cycle colors when the power is applied?


Yes, the lights to cycle when the power is applied but no lights are on after that. Update I get a flash of red light when it tries to connect.
