Hi WAEL02, Security Merchants also deal with HIKvision which appears good, DS4004/8HCI might be worth a look at. These cards I beileve are full PAL / NTFS (realtime) at minimum CIF for similar cost to magic radar. The H/V are stackable and mixable (4 ch & 8 ch in the one box), some do an IP camera mix with STD cam's. With 2GB RAM the rest of you system is fine. As we know, the software can make or break DVR cards, HIKvions seems okay. I understand that GeoVision is very good to, bit more cost wise. Good luck.
