Tech Tips


    Images may be unclear even in normal conditions if:

  • Electrical devices are used in the cabin (noise may occur in the image).

  • The camera lens is frosted over (the image immediately after turning the power switch on (IG) may be blurred or darker than normal).

  • 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.

  • The television camera assembly lens has drops of water on it or the humidity is high.

  • When the camera is used under fluorescent lights, sodium lights, or mercury lights, etc., the lights and the illuminated area may appear to flicker.
