So I just installed some cameras in a newly remodeled store. I installed the original cameras 5-6 years ago and they were analog surface mounted cameras. The architect drew some circles on the new plans and called them cameras and said they should be flush mount. I redrew the camera locations based off the dimensions and thought it would be nice to do some flush mount cameras since I generally don't do a whole lot of new construction.
I used the IPVM product search and past discussion searches and used one 3MP Dahua for the door camera and then used the Vivotek FD816C-HF2 for the overview cameras. They are working well but they are supposed to work with WDR on. The problem is I have a flickering issue and the whole entire store from the ceiling light fixtures to the display cases are 100% LED. If I adjust the flicker which adjusts the exposure settings, the problem goes away. However, once you turn on WDR pro, the flicker settings are grayed out and the issue comes back. The benefit of WDR in this case is to get a better view of the display cases. Now the IP cameras work much better than the analog ever did, but I'm not sure how to resolve this issue. Below are images. Please note these are photos of the screen but you should be able to see the problem. Thanks. I don't have the issue with the Dahua camera, but it also doesn't have WDR and is facing the door entry and WDR isn't necessarily needed.
