This is an old CCTV system and I no longer have any documentation. The software supports up to 4 cameras but I've only been using one for the last few years. Recordings are made via a Dell Laptop to a USB 500GB HDD. O/S is Windows 7 and I'm now getting the problem "iCatcher for MARS has stopped working" at frequent intervals, at which time I have to close and re-start the app. I've looked for but can't find an updated version of the software. Would appreciate any suggestions please?
