InBio controller firmware can be upgraded in the field. InBio panels stores up to 3,000 fingerprint templates, 30,000 card users, and up to 100,000 events/transactions. InBio is backed up in real-time to an on-board SD card. Data is preserved if power is lost. InBio continues to operate if network connection is interrupted. Along with relay contacts for controlling door locks, easily programmable auxiliary relays can be used for additional control and interface to lights, alarms, annunciators, intrusion detection panels, or even extra locking devices or gate controllers.
