With fingerprint and face recognition, and app compatibility, models can identify authorized users more accurately.

With keys, access cards and passwords at risk of being lost or copied, makers have made smart door locks 'smarter' by adding the capability to recognize authorized users' fingerprints and faces. A number of releases can also be synced with mobile phone apps for remote monitoring of status and control. Adding, deleting and freezing users, and checking opening records are administrator tasks done easily on smartphones.

This does not mean though that typical unlocking mechanisms are left behind in terms of improvement. Some makers designed units that hide combinations within other characters to prevent these being copied, conceal password panels and card readers, and sound alarms when entry fails for a number of times.

The products in this gallery represent current trends in smart door locks.
