Hi i tried to downgrade DS-2DE2202-DE3 5.3.0. to 5.2.5 but after the downgrade i cant see camera in the network. i try a SADP app from hikwision to look for but no luck. After that i send PW to @alastairstevensonhe told me thats firmware its wrong for this camera And send me link to correct fw for this model but i cant upload this fw to camera now
