Implementing biometric access control systems is considered the highest standard for securing areas because it relies on verifying unique individual traits such as fingerprints or iris patterns, which are extremely difficult to duplicate, offering a superior level of security over other forms of access control. On the other hand, using coded access cards can be more vulnerable as they can potentially be stolen or cloned. While installing surveillance cameras, known fully as closed-circuit television (CCTV), can be a strong deterrent and provides a way to monitor and record entrance to facilities, it does not inherently prevent access. Likewise, sign-in logs offer visibility into who enters a server room but rely on manual verification and do not provide the same high level of security validation as biometric systems.
