Just bought the hikvision NVR and two ptz mini cameras and I cannot get it to work on my pc or use ivms 4200 on the ivms 4200 I can only see my NVR connect but I cannot add any cameras it says not recognised but the cameras are online. However when I connect the HDMI to my TV I can see the cameras working but I cannot get it to work on my computer. I know that the cameras are working but I can't get it to work on my computer to set any features such as auto tracking someone please help me.
