urghh..........cant post link

really nothing to see completely white fog goes from good picture to white fog instantly

Have installed wired camera and dvr system. all working well until evening. at the precise time when the street light goes from red to yellow the image from one camera goes from normal/infrared to white haze. next morning as light switches off so image is restored. Any thoughts as to likelyhood of being the street light, what distance away from same might interference stop, is it light or sound? etc etc
