I have 3 v2 cameras and an very pleased overall with the cameras. One issue I have is that during dusk and dawn when the ambient light is switching from day to night or vice versa, the camera switches from day mode to night mode and back several times (as frequently as once in two seconds) before setting down. This can be fixed through a firmware update. One way to fix this is that in auto, the day/night mode gets locked down for (say) 30 seconds before it can change. This will prevent the rapid switching between day and night mode.
