Accurate PTZ + Joystick For Object Tracking

I need a smooth solution for joystick control for a PTZ camera.
Got to have really fast resonse time and accurate controls, similar to the old analog PTZ cameras.

I tried with dahua HDCVI, but looks like the PTZ is limited to move in 8 directions, and with the NKB1000 the speed of movement is fixed, and not linked to how hard the joystick is moved.

Can someone recommend a setup that will do this better?
