Welcome to the forum. To my knowledge challengers did not come with a front camera from the factory. So it sounds like you have an aftermarket set-up, without knowing what you have it's hard to diagnose. Most likely you have a bad connection somewhere or the camera is starting to have issues.
Previous owner may have installed a Coastal Tech myGig Lockpick and then added the camera. I'd check out their website and if you can recognize the hardware installed somewhere in your LC, perhaps they can help you troubleshoot it.
