The Di T91 smart door lock is fitted with fingerprint recognition technology. With the help of an inbuilt AI system, which can predict changes to the fingerprint, it continues to work quickly and reliably even after opening and closing more than 100,000 times. The semi-automatic locking mechanism is integrated into a sliding cover which closes automatically when touched lightly, thereby making it easy to operate. Additional extras include smart cat’s eyes, which enable remote monitoring.
