Hi i have a slight problem with my Geovision DVR250 Card if i place any black & white cameras in any of the 4 ports it disturbs the overall pictures on the other cameras it fluxuates from bright to dark but when i install all colour cameras the picture is fine what happens when i install day / night cameras will this disturb my pictures when they change from colour to black & white.
I also have a GV-NET Card that i would like to connect to my PTZ Cam but when i enter I/O Device & Format Address as the manual describes i just get an error message quoting Not GV-IO in COM1 when there is connection to COM 1 i have had COM1 tested & its ok & all the connections are correct do i have to Configure the GV-NET Card with I/O Devices ?
