Are you able to include something similar to a sun-lit lobby with glass windows or door for the shoot out (wdr)? Can’t wait.

I love Dahua USAs new part numbers! (NOT!) I believe this model is really the same as the older DH-IPC-EBW81200 model, maybe with a firmware update. Maybe one of the Dahua OEM guys can pitch in here and confirm/deny this. If so, we have been using this model for a few years now with OK results. They work well in small overview areas. We generally prefer the Samsung/Hanwha fisheyes. The biggest drawback to the design of the Dahua fisheyes is the silly mounting plate. It is a PITA!
