[Peterdb]

I have recently purchased 4 Kucam 1029p HD cameras ,

I also have a Liview NVR only a cheap on from here:

The cameras work fine excellent picture both on the Net and on my phone & Tablet .
However the NVR will recognize these camera but will not display anything as it shows either "no connection" or wrong Password"
I have changed the password many times and I know its correct does anyone have similar equipment that can advise me ?
Also I realise this is a very cheap NVR can anyone recommend an NVR at a reasonable price that is compatible with Kucam Cameras'
