What is the purpose of having backup power for an EAC system?

Having backup power for an Electronic Access Control (EAC) system is essential to ensure continued operation during power outages, which directly maintains the security of the premises. In situations where the primary power source is interrupted, such as during severe weather or technical failures, the backup power supply ensures that the access control mechanisms—like electronic locks, card readers, and surveillance systems—remain functional. This uninterrupted operation is crucial for securing sensitive areas, granting authorized access, and preventing unauthorized entry, thus enhancing overall security resilience.

While options like improving efficiency, providing lighting, or enhancing speed may seem beneficial, the fundamental purpose of backup power is to maintain operational integrity and security during power disruptions.
