Just so I am clear on this. The NVR normally uses a different IP Structure for the Camera 'network' managed by the Internal NIC
That's correct. See attached PDF
By default now Hikvision ships all cameras with a default IP of "192.168.1.64" " user admin" "no password."
They are true Plug and play to a Hikvision NVR just plug in and they obtain the NVR log in password and the internal NIC IP for the POE port.
I had one arrive today unpacked it, connected in to a spare port and 15 seconds later is on line.
By connecting a laptop with SADP to a spare POE NVR camera port it's possible to edit a non connected camera address from 192.168.1.64 to match the internal NIC camera port.
From what has been posted I believe "vette-kid" has his own password on the NVR and has connected two non hacked cameras by plug/play.They will now have a IP in the range of 192.168.254.* and his own Password from the NVR. (see post 1)
The hacked cameras are not true plug and play for the first set up unless the NVR password is the same as the hacked cameras.
That why we need SADP to change the camera address from "192.168.1.64" to match to POE port. Then they should connect with manual password input.
Once connected the password can be edited and port change to plug/play.
Method two was with the other cameras removed, change the NVR password to match the hacked cameras password set the port as plug/play, then if the hacked cameras has DHCP they will connect. Once all are connected change the NVR password to his own one and it will transfer this to all connect cameras.From there he can reconnect his other cameras.
There's a third method to connect these.You need a 12V DC power supply for the camera, disconnect a computer from the network, set its IP to use 192.168.1.0 range and connect the camera direct to the Lan point. Goggle and this forum is your friend here.
