no answer i am afraid so far

Hi Jong, Yes I have tried a different camera seperately with a different power supply which works fine on a monitor, but same problem with the Gv1480 system.

Hi Soundy, Yes I've tried it only one camera and a seperate test camera still no luck I'm afraid.

Hi all, Hope there is someone out there who can help or give insight to any similar problems they have had. I have a GV1480 running on a Dell with Quad core . The system has been running fine for 2 years , but over the last few months I have got horizontal lines on all my cameras which severly distors the video image for live and recording. I have installed different windows from xp to windows 7, updated drivers , tried Geovison 8 - 8.3.4 but nothing seems to work I still get same image on all cameras. I have all tested the cameras and they give a perfect image when connected to my monitor. All tested the gv1480 system with a different camera, no change. Any help guidance would be much appreciated. Is this a Pc or 1480 card problem, I still need to get hold of another pc to test if it really is the card, To me it seems it is the card if so how to return if past warranty or get it repaired? Please help Jason
