Legacy physical key systems create visibility gaps and serious operational risk. When keys are lost or copied, there is no audit trail, no instant revocation capability, and no way to know who accessed what area and when.

Modern access control replaces physical keys with encrypted credentials — RFID fobs, mobile phone-based access, PIN codes, and biometric readers — each with complete access logs, scheduled policies, and instant remote revocation.

Integrating door events with camera footage adds critical accountability. When a credential is used, the corresponding video clip can be immediately retrieved — transforming your access control system from a lock manager into a complete security audit platform.
