@MASPR so I figured this out after disconnecting and connecting the camera from the network I have to first log in to the hikvision ip camera and then log in to the camera in tplink nvr and only then...

I attach to the nvr from tplink camera hiklvision hwi-t240h sometimes I manage to connect it but after a power failure (the camera turns off and on) the nvr always says unauthorized on the cameras....
