the camera does a loud clicking noise every time the night mode is on/off and at random times, which would wake up/scare any baby.

After complete setup, the cameras continued to make lots of loud clicking noises throughout the the day and night

It picks up a lot inaudible white noise

I get a static constant noise where on the other one I do not.

First, I'm not sure what switching takes place between night vision and normal modes, but every time the camera switches between the two modes it emits a fairly loud clicking noise

when the camera switches to night mode a shudder must move in front of the lens which causes a rather loud noise

Excellent I really liked them a lot
