How does a "deadbolt" enhance EAC security?

• A. It adds aesthetic value to doors
• B. It provides a stronger locking mechanism that is resistant to unauthorized entry
• C. It allows electronic access via mobile devices
• D. It is easier to install than standard locks

Answer: (B)

A deadbolt enhances Electronic Access Control (EAC) security primarily by providing a stronger locking mechanism that is resistant to unauthorized entry. Unlike standard spring bolt locks, which can be easily manipulated or forced open, deadbolts have a solid metal bolt that extends deep into the door frame. This construction makes it significantly more difficult for intruders to gain access through physical means, such as picking or bumping the lock.

In the context of EAC, deadbolts serve as a critical physical barrier that complements electronic systems, ensuring that even if electronic access systems are bypassed or fail, the deadbolt remains a formidable barrier that enhances overall security. This dual layer of protection—physical and electronic—helps create a more secure environment for sensitive areas.
