IT Home, November 13 news: Huawei announced on November 12 that the Huawei Smart Door Lock 2 series has been fully upgraded to HarmonyOS 7.0, bringing three major features: homecoming snapshot, call voice changing, and doorbell call to car.
IT Home lists the main contents as follows:
- New homecoming snapshot: when family members (children, elderly people, etc.) come home and unlock using face or palm vein recognition, the door lock automatically captures a snapshot of the family member coming home, allowing remote monitoring of family activity.
- New call voice changing: supports voice changing during intercom conversations with strangers, safeguarding the safety of women living alone.
- New doorbell call to car: when no one is home to answer the door while driving, the door lock automatically calls the car, and the car owner can conduct a visual intercom with the visitor through the car.
