Thank you for your input.
The camera has been set up, and attached, and was fully operational as expected (throughout the day and night) for 2 days.
This issue occurred on the third day without any changes, physically and on the app options - because there was no need to.
As for the clicking sound, I wasn’t aware that there were any mechanical components in it. Thanks to you, now I know because you asked me to take listen. I will do that tomorrow during daylight and will let you know if I can hear the clicking sound or not while I turn On and Off the IR. I get zero lumens at night, When I turn off night vision in darkness, the screen is greenish, showing very, very, very little of the subject matter - when the night vision is turned On, the screen is black since the surrounding is extremely dark.
I do have 4 other Wyze cams (several models) running simultaneously without exhibiting any issue with night vision in darkness.
All protective films were removed at the time of the initial setup, night vision worked exceptionally well for two days and two nights.
Additional note: This cam is attached above a WCOG, both aiming in the same direction, monitoring the same subject. Shouldn’t the IR that’s being emitted via the OG be enough to at least help light up the screen view so that the OGT lens sees something besides a black screen?
I was wondering, what does the toggle [Night Vision IR Lights] do other than turning Off and On the IR LEDs on the camera itself (I mean any fully operational Wyze cam)? The subject is lit in NV just the same, as long as the NV option is turned On or on Auto in the dark.
I finally realized… of course it’s an important option and it must be turned On in NV or else the screen would be dark. The reason why I couldn’t tell the difference when I was toggling the Night Light option of the WCOG On and Off was because the IR of the WCOGT was toggled ON. Even though the NV stopped working on it (because of something entire different), it’s still emitting IR. And since they’re mounted on top of each other, also aiming exactly at the same subject, turning On and Off the WCOG bellow it, the difference was so miniscule, one cannot tell. Therefore, as far as the WCOG in NV mode at night, it still could see clearly in NV even with its own IR light toggled Off - as long as the defective WCOGT above it, the IR Light was toggled On.
*** I still haven’t heard back from Wyze regarding the original issue that I stated in the title field. It seems my camera is the only one that’s can no longer see in the dark (while its own + the WCOG IR LEDs are all lit) after only been used hardly for 48 hours.
