Furniture Accessories, Hardware and Materials Design Smart Lock Remote Visual Intercom by Shenzhen MTC Digital Technology Co., Ltd Smart Lock is a smart door lock with a remote visual intercom, designed for home entrances. The lock supports several unlocking methods, including face recognition and finger vein recognition. Three-dimensional structured light face recognition helps prevent access with photographs or videos. The front of the handle reads fingerprints and the back reads finger veins, so the door opens with a grip. The lock case is made of aviation aluminium with a tempered glass cover panel. A cloud connection allows users to check the lock status and to set its functions remotely.
