What do you mean by hijacking a police officer?

Hijacking alarm is also hijacking alarm: that is, everyone can set a special unlocking method when entering password, fingerprint and key card in the door lock. When there is an emergency, such as someone threatening to open the door with a knife, you can use this special unlocking method to unlock the door, and the door lock will open normally. However, the door lock will send hijacking alarm information to the set emergency contact through mobile APP message push, mobile phone short message and other forms. Although this function is not commonly used, or may never be used, it is strongly recommended that you must have a hijacking alarm when buying a door lock! Maybe a critical moment can save a life!
