Security camera security

If your CCTV security camera system uses IP transport to cut costs, don't forget to factor the cost of network and device security into the mix. It has long been known that many IP-enabled CCTV cameras are pumping live video onto the Web with no encryption or access control. It now appears that exploiting security vulnerabilities in the camera controllers may allow hackers (or bank robbers) to manipulate the video stream, for example replacing it with a 'blank scene' while they crack the vault.
