I'm working on a case where evidence and eye witness testimony establish that a gun was fired, and the incident was captured on a Ring camera in Night Vision mode, but no visible muzzle flashes appears in the video.  

There is a lot of contradictory information on the web regarding the wavelength of light produced by muzzle flashes and what wavelength light Ring cameras in Night Vision will capture.  Enough contradictory information that it's difficult to make a defensible argument either way.

I'm curious if anyone has actually seen muzzle flashes on Night Vision mode video from Ring cameras?

Thanks for any help you can give.
