Turning on night mode does nothing

I can set night mode setting from my wyze cam v2, when I changed mode from say off to Auto or auto to On, for split second I can see video in night mode ( gray video ) and then everything is pitch dark black.

Is there any other settings that I’m missing?

Why can I see night mode for a sec or two and then it goes back to dark?

Why those Infrared lights doesn’t stay on during night time, even when night mode is ON and not off or auto?


Any suggestion? could it be hardware issue?
