Hello, my geovision GV-1480 has been working fine and I have been able to go to geovision.com.tw to download new version. Everytime, Geovsion site would ask me to input the serial number on the back of the card and they would email me the link to download the new version. Well, the last update with Geovision was 8.2 was fine but after that, Geovision didn't reply my email any more for the link to update so I went to ezcctv.com to download the 8.4 and it worked without the hitch. Until last week, I updated again the 8.56 driver and installed the version but now sometimes the system pop up something like "..you may be the victim of counterfeit hardware.." or that affect and it kicked out the desktop screen. Can someone here help please.
