I bought one of the IP Cam Talk 4 MP IR Varifocal Bullet Network Camera, IPCT-HFW5231RE-IZS and installed on a LTN8816 NVR from LTS. Great camera with very clear and bright picture. The only problem I am having is the NVR does not recognize this is a PTZ camera and will not let me use the zoom and focus features. I can log into the camera on a web GUi and it works with no problems, just not able to use these features on the NVR. Anybody got any ideas?
