I Have a Dahua DH-SD49425XB-HNR PTZ camera , the illuminator used to work very well, now its not illuminating the field of view very well, specs state the cam has 4 lamps, only 2 are lit at night now. Vendor I purchased from not very helpful. Tried all the settings in the IR field settings , compared to my bullet and dome cams. Anyone know for sure this cam has 4 IR LED's, can't see beyond the black screen where the IR's are ( night or day ). Cant find parts for the cam or I would replace the illuminator board myself
