Why do my Flux cameras have lines going up and down the screen?

More than likely you are talking about an analog camera. This can be caused by a few different things.  Firstly you may be experiencing electrical interference.  This is most commonly caused by flourescent lighting or large electrical equipment.  Typically this can be resolved by purchasing a ground loop isololator or re-routing your cabling. 

Another cause of this issue can be not having enough copper in the cable you are using, more than likely due to using a low-quality premade BNC cable or a failing power supply. Check out PNP60 or PNP100 for guaranteed quality premade cables that have enough copper to support HD analog cameras. 

Lastly your coax cable runs may be too far.  If possible, you will want to cut your cable length down and put on a new BNC end. It’s suggested that your cable not exceed 300ft for standard analog camera and 820ft for HD analog cameras.
