NVR error message - The login return time is up

Hi

I have brought what id thought was a plug n play system.

8 Channel NVR with ONVIF 4MP cameras, plugged them in and on the monitor no images show but get a message stating ip address and underneath says "The login return time is up".

Any idea what this means, there is power to the camera. The ip address shows 10.1.1.29. Does this need to be configured to an internal ip address?

Thanks

Vic
