Hii hope some one can help me i have a go vision dvr with 4 hiksvision colour cameras. my XVRView app works fine on wifi. But on cellular i get 0 fps and only max 200 kps. if i press the hd button the speed drops to 0. i have reseted my dvr played with the encode setting with no improvement . I have a 1 gb upload and down load speed since a weeks so my app should work better. before i had 0.5 upload and 12 mb down and my app worked better than now. i have opened the port in the router with no luck. Or i do some wrong here?i am considerring to buy a new dvr maybe hikvision to solve this issues. any help would be epreciated before i go this route
