Hi good morning I have a problem with the operation of the camera joystick type WV CU - 950, there are 2 PCs connected to one DVR, when operating the joystick, only PC 1 runs normally, pan tilt zoom, but on pc 2 the functions on the joystick do not run at all. Only pan and tilt function. And the zoom, wiper, etc functions don't work, it should work, because the two computers are stand alone, can anyone help? , I would be very grateful if someone gave the best answer ... thank you
