Your company is upgrading the CCTV system that monitors sensitive areas such as data-center entrances and stockrooms. Which action would BEST enhance the video-surveillance component of physical security?
Reduce the recording frame rate to 5 fps to conserve bandwidth
Disable infrared (IR) illumination at night so cameras are less noticeable
Shorten video-retention time to seven days to save storage space
Replace the existing cameras with high-definition IP cameras
Replacing older cameras with high-definition (HD) models increases pixel density, giving clearer images that make it easier to identify faces, license plates, and other forensic details. Lowering frame rates, disabling infrared lighting, or sharply shortening retention periods all reduce surveillance quality and therefore do not strengthen physical security.
