Speedometer alert I don't understand

My wife wrote and told me she saw it tonight after the car sat in the driveway for several hours. temps had dropped to the upper 20's when she left. The message:
"System Disabled Due to Poor Outward Camera Visibility" Has to be fogginess from the cold temps. never have the issue when its in the garage.
 
I get the "System Disabled Due to Poor Outward Camera Visibility" some mornings when the angle of the sun is very low with intense glare.
