is it possable to conect micromark cams to a pc the system i have is 4 cams that all plug into a b/w monitor

that depends on the tyoe of hookup for the pc capture card

and also depends on if the cameras recieve power from the monitor or splitter.

if they do recieve power from what they are plugged into you can usually split the signal and connect it to a PC based DVR card or just a regular DVR
