I run a wireshark packet capture while the camera is booting on the network and check for ARP packets from the cam as it starts up and attempts to get/verify it's IP address.
then, if needed, change your PC IP to match the cam's network , get into the UI and give it a valid IP on your LAN...
Also, it could be that one of your existing cams is already using the default address the new cams come with. Try (temporarily) disconnecting your other cams from the net and see if your new one shows up...
The default address is 192.168.1.108. disconnect the camera an try ping that address, if you get a response you will need to disconnect that device or change that devices address.
Does anyone know if I can use google Remote Desktop to change IP of router etc to 192.168.0.1 and check there for the new cam or will I lose my remote connection?
