It’s not possible to use the cameras in night vision mode without being detected because the IR LEDs are 850nm and therefore have a faint, but visible, red glow to them. NOT very discrete. I realize the 940nm may not offer the same distance of illumination, but for those who need discrete monitoring, that’s OK. Maybe offer it as an option?
The wyze cam pan has invisible LED so yeah, we know it is possible to have invisible LED. I predict that the wyze cam V3 would have invisible LED.
