@Yoshi95 I've had the exact same problem with 2 NC450 cameras, one of them now doesn't make that popping sound upon starting and now it stays on for a while, but it doesn't show any live camera feed...

Downgrading from 1.4.1 to 1.3.4 didn't really solve the problem for me After a while, the image of the cameras get flipped upside down, i have to "preset" them all the time. This never happened to me...

Thanks mate!

@Kevin_Z I also need to downgrade the firmware please, i've sent you a message
