Good home design, not only to protect safety, but also to create a sense of homecoming ceremony. The core bright spot is the electric telescopic handle, which can be closed seamlessly and tamper-proof in standby. Automatic pop-up when identification is close, side light guidance, smooth unlocking interaction. Equipped with 170 ultra-wide angle double camera, AI scene recognition, intelligent linkage of the whole house, and ten unlocking methods, the door lock is upgraded to the first stop home.
