Interesting. 7108 has ptz controls. Second thing I found is 7104 doesn't have nat configuration setting in the ivms 4200.I have this connected up to a ds-7104sn/p but cannot seem to get any ptz controls via the ivms4500 app on my mobile, says not supported by the device, any ideas?
*EDIT*
appears that particular nvr does not support pTZ controls,
