These security devices are electromechanical locking mechanisms commonly found on safes and vaults. They utilize a combination of electronic components and mechanical bolts to control access, offering a higher level of security than traditional key-operated locks. One example is a lock featuring a digital keypad that requires a specific code for the safe to open.
The value of these systems lies in their robust design and enhanced security features. Historically, they represent an advancement over purely mechanical locks, providing audit trails, time delays, and multi-user capabilities. This evolution allows for better control and monitoring of access, minimizing unauthorized entry and internal theft. The ability to program these locks with different user codes and restrict access based on time of day contributes significantly to loss prevention.
