A push-pull lock opens the way a door should: authenticate, then push to come in or pull to go out — the handle itself is the release, so there is no turning a knob with a hand full of shopping. The DG 406 recognises a face in 3D from a distance, reads a palm without contact, and takes a fingerprint from any angle — nine ways in altogether, with up to a hundred fingerprints and cards and fifty faces and palms on file.
It also watches the door: an HD wide-angle camera and an integrated video display show who is outside, an audit trail records every entry, and a one-time password lets a guest or a tradesperson in without a key changing hands.
Every model raises an alarm on a forced door, a fire, a flat battery or a lock left disengaged, and offers an auto-locking mode that secures the door behind you and a privacy mode that keeps the outside handle dead while you are home.
Supplied and fitted by M&F Studio's automation team. Integration with a video door phone or a home automation system is confirmed at the site survey, against the system the home actually runs.
