Hello.
I just bought more Wyze V3 cameras at my local computer store. Setting up the new ones today and one of them when you plug it in makes a high pitch noise from the power wall brick from wyze. The other cameras have not done it. But to be sure it was the brick, I have disconnected the camera and plugged in my iphone. Still a high pitch noise. Then I plugged the camera into another usb power brick and no noise. Plugged the original power brick and the high pitch noise is back. Anyone else have this problem?
