Thank youAll the features work perfectly. I use the Dahua Config Tool which is a free download to initially set up the camera. I have not tried plug and play with the Dahua cameras or the Hikvision cameras for that matter in a number of years. There is a difference between the 4mm and the 2.8mm in my Hikvision 4k cameras but it is not that big. I do not have a 2.8mm Dahua camera to compare to my 4mm Dahua camera. Here are a couple of pictures from my Hikvision cameras. Top picture is 2.8mm and the bottom picture is 4.0mm. These are both 4K cameras.

Since you assured me according to your experience that features of
(DS-7608NXI-I2/8P/S) NVR like recording 4k and 265 or 265+ and stream in high quality 4K, motion detection (basic smart event,human car.. etc) It will work fine, I will buy the camera
