I have Tucson Hybrid Limited and, as far as I am aware of, this car does not have "Speed Camera" options. If it was a typo or text prediction inserted "Speed camera' but you meant "speed limit" warning, then it can be found in "Setup" - "Vehicle" - "Driver Assistance" - "Speed Limit Warning" settings as well as "Speed Limit" volume settings (where you can turn it off, if you want to).
I am also wondering if by saying "speed camera" warning, you may be referring to warnings of speed cameras from either Google Maps or Waze or some other app on your phone?
If so, that would be managed from the phone itself.
However, if your car, in fact, does have "speed camera" warnings - what trim your car is?
