- The camera lens is dirty with snow, mud, etc.
- A strong beam of light, such as a sunbeam or headlight, hits the camera.
- It is too dark around the camera (at night, etc.).
- The ambient temperature around the camera is either too high or too low.
- The vehicle is tilted at a steep angle.
- The television camera assembly lens is scratched.
