Windscreen camera misting

I've had my HS PHEV for almost 2 years now without any problems until yesterday. The auto headlight dip stopped working and I noticed that the camera was no longer reading speed limit signs. I can see that the windscreen is misting up in front of the camera. Some other manufacturers have a mod installing a heater by the camera to prevent condensation. Is there a modification for the MG to resolve this issue?

Use some heat to clear it.
