Think of door controllers as the brains of your access system. Ever had a power outage or network issue and worried about door security? Modern controllers are smart enough to keep working even when systems are down. They remember who’s authorized and maintain security logs until connections are restored. We’ve helped businesses like medical clinics and storage facilities ensure their doors stay secure even during technical hiccups. These systems can also trigger automatic lockdowns in emergencies – crucial for schools and office buildings that need quick response capabilities.
