It's not clear to me what issue you are experiencing. When the camera is live streaming or detecting motion at night, the IR LEDs will be active to enable night vision mode.
Are you saying the camera recordings as expected during the day but is not recording at night? What mode are you using?
I've opened and escalated a support case detailing the information you've provided here. An agent will reach out to you as soon as possible with a status update.
I've spent months sorting out issues and working out what's what on my own pro3's, what I can say is when these cameras are on battery or still charging, the ir lights only come on when detected movement as the camera would go flat faster.
But when fully charged the camera goes into the 3 second look back mode, so the ir lights have to stay on all the time as the 3 second look back would be pitch black for those 3 seconds.
What I can't say is why yours won't record at this point, only thing I had before was using an after market outdoor charger which didn't have enough volts to use camera once motion detected so the camera would freeze.
Maybe no help to you
Like I say don't know why yours won't record though
