Worm

In recent weeks a worm, a malicious software program, has swept through corporate, educational and public computer networks around the world. Known as Conficker or Downadup Experts say it is the worst infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world. Conficker harness infected computers into unified systems called botnets, which can then accept programming instructions from their clandestine masters. It might operate in the background, using the infected computer to send spam or infect other computers, or it might steal the PC user’s personal information.

If you were serious about your CCTV deployment, it is a must to have a dedicated computer to host the PCI DVR card. In other words you should not use the same PC for any other purposes but to run the DVR main server program. A dedicated PC server will definitely reduce the chances of infecting computer viruses and hence reduce the down time of the DVR.
