For which security-related reason SHOULD staff monitoring critical CCTV systems be rotated regularly during each...

Regular rotation of staff monitoring critical CCTV systems is recommended primarily to address the limitations of the human attention span. Research suggests that the average human attention span during intense monitoring tasks is approximately 20 minutes. After this period, vigilance and alertness can significantly decrease, leading to a potential lapse in monitoring effectiveness. Rotating staff helps to ensure that individuals are always at their most attentive when observing the CCTV feeds, which is crucial for maintaining security and safety standards. This practice also helps to mitigate risks associated with fatigue and the potential for missing critical events or details.
