Hi, from what I understand of the spec, the 7208HIHQ-K1 supports 2 ip channel. There are 2 PoE ports at the back? Usually the DVR that supports IP doesn't come with PoE ports, just one single LAN.
You'll need to run your IP through a network switch, preferably a PoE one so you don't need to power your IP PTZ separately. So basically you connect camera -> switch -> DVR LAN.
