Hello Richard! The 1TouchIQ2 is a single latch that is used in many homes within the entry and to secure doors within. A more complex system with more management abilities have also been installed in homes with much needed security such as the Suprema and ACTAtek products. You can find many examples of useful contemporary products at www.FingerprintDoorLocks.com. The 1TouchIQ2 can be found at www.1TouchLock.com. I hope this was helpful.
