Guardian X8 is the X series of high-end intelligent door lock. A fully automatic lock core is adopted, and a wholly integrated system sits at the core of the design, which seeks to fuse the relationship between the lock and door while bringing about a more robust appearance. A fingerprint sensor is incorporated into the upper part of the lock handle. The fingerprint authorisation and the door pushes open simultaneously, which reduces steps in the whole process and saves time. Additionally, Guardian X8 can be linked with other smart home appliances and intelligent security devices.
