Please be sure you purchased the Geovision card from a genuine Geovision dealer. You can check here for unauthorized dealers:

Having recovered means there was a problem before. try to install the device drivers for the video capture card all over again

PCI

Okay - try going into the software directory and delete the files maked .db there should be one for each camera. Then start the software and try it again.

yes you can, but recording will depend on size of hard drive. i work in the trade and you will require at least a terra bit to run 32 cams for any given period

This problem could be because of the GV card version not compitable with GV main systems software you install please check the hardware version of the GV card and compare for compatibility. East way out downgrade to lower version of software. for example if you have version 8.1 install then install version 7.0 or something like that.

turn off reboot in system config if cam loss
