zacharyx 0 Posted February 18, 2017 Hi guys, new to the forum and looking for a little help. I am using HIKVision 2CD2142 and 2CD 2542 in 2.8mm and 4mm. The issue I am having is that after a few days the ones I have WDR enabled on become grainy for the night pictures. They look great for the first few days and sometimes weeks but they eventually turn grainy. I can turn WDR on and back off and they are fine for a while but the picture quality eventually get worse over time. Any help will be appreciated Share this post Link to post Share on other sites
GadgetAssistant 0 Posted February 18, 2017 Hello. It could be either the mounting of the camera or inadequate power to the camera. Share this post Link to post Share on other sites
zacharyx 0 Posted February 19, 2017 trying to figure how resetting turning WDR off and back on would fix an issue with either but I will check to see if there is a mounting similarity between the cameras doing it. As well as see if the ones with POE off the NVR vs a switch is a difference Share this post Link to post Share on other sites

DS-2CD2142FWD-IS, 74ft of cat6 POE off the same switch. again 1 hour after turning WDR off and back on Another location that I do not have an after picture for since I have not been back out recently, this is a week or so after I turned WDR on, the picture was dark but clear for the first couple days DS-2CD2542FWD-IS , POE from DS-7716NI-SP, mounted on the side of the house, 46ft cat6 Share this post Link to post Share on other sites
