Just got off the phone with SS. S/w Clay.
His explanation for the noise is that when the night vision light comes on, the lens is changing from color to black/white, and that the internal mechanism has loosened up and is moving faster, thus making the noise. He said there is probably a screw inside that needs to be tightened. I asked to have the camera replaced. He said likely in 6-12 months it will exhibit the same behavior. He was basically implying that there are two lenses, one for color, one for b/w.
Remember, I keep the shutter open at all times.
I call bs on the explanation.
But anyway, I will replace the one in the bedroom since it bothers me while watching tv. The other two I am not too concerned about at this time.
Probably not a lens for B&W and for color, per se. I'd say more likely an IR filter being moved when the camera switches to night mode. IR filter in front of lens/image sensor for daylight mode, moved out of the way for IR/night mode.
Yes, the night mode is not black and white because it is reconfigured for that; it is actually infrared and lack of infrared (or "heat" and "cool"). The filter theory sounds much more reasonable than separate lenses.
Then you didn't understand the answer. The IR filter physically moves, thus makes a click, when the camera switches between day and night mode. The day/night mode switch happens regardless that the shutter is closed.
Below is a link to a short video I made. There are several clicks. The louder more "klunk" ones are from the room light switch. The clicks of significance are the softer ones just after the room light is turned off and back on again.
The shutter is closed the entire time. You will note the camera clicks twice in response as it changes from day to night mode (one click) then another click when it changes from night to day mode. Those clicks are much more audible in person than in the video. You also see the IR LED come on and go off in conjunction with the clicks.
Not sure if will help your scenario or not but it did mine. My house is borderline dark all the time even in the middle of the day, yes I am a cave dweller. My camera in the LR was constantly clicking so I went into the camera settings and switched the "Night Vision" setting into "On" and this has eliminated the clicking on this camera. Hope it helps, I fully understand how irritating that constant clicking can be.
If you go to the night vision setting for your camera, and switch it on, then off, you'll hear the camera make the same clicking noise.
I too believe it is switching an IR (Infrared) filter in from of the lens and electronically interpreting the color camera output as black and white, to get a better picture.
So even though your shutter never opens, the camera is changing mode (when on auto) depending on the light level in the room.
@daveandvickie this is correct. There is a quiet click when the camera switches to Night Vision mode, and it does this whenever there's enough of a change in light level. So it can be ready for when a recording or stream comes on.
