CCTV set up

Hi


I have 3 Motorola Focus 73 cctv cameras , I set one up to test via wi-fi with my i-phone and works ok , , but I need to set one up away from my wi-fi signal using a power adapter and also I want to see the camera's on my pc , they are speaking to each other showing all green lights ,but I can not get to see the camera on my pc , is there a different set up to use for seeing the camera on my desktop pc ,the instruction manual is very vague on pc info
