We recently installed (10) Direct connect color outdoor dome cameras. The specs are:
1/3" Sony super had ccd
560TV lines
NTSC/DUAL
DC auto iris varifocal lens 2.8-12mm
The image looks terrible at night and has some sort of haze in the center of the image. We have done at least 150 of these cameras before with no issues.
We replaced them once already and the manufacturer has no idea what is going on.
