ZKTeco Facial Push-Pull Mortise Lock HBL400

The ZKTeco HBL400 is a fully automatic smart mortise lock combining 3D structured-light facial recognition with fingerprint, IC card and password access. It is intended for residential entrances where the lock also provides a way to see visitors from inside. The documented capacities are 50 faces, 100 fingerprints, 50 IC S50 cards and 50 passwords. These separate credential limits describe this model's enrolment resources rather than a single combined user-capacity figure.

A built-in 720p camera and 3.5-inch indoor LCD provide a viewing arrangement at the door, while the supported ZSmart app adds mobile management. Communication uses 2.4 GHz Wi-Fi under the listed 802.11b/g/n standards. Facial recognition is specified at 0.5–1 metre with a recognition time below one second. The chosen mounting position must therefore suit the person presenting their face as well as the physical door hardware.

HBL400 uses a Chinese-standard 6068 mortise, with a listed door-thickness range of 45–60 mm and customisation available from the manufacturer. The outdoor and indoor assemblies are each 400 mm high, so replacing an existing lock requires a check of the door preparation and available space. A 5V Micro USB emergency interface, doorbell function and random-password support provide additional operating features. Confirm the ordered door configuration and app setup together; the manufacturer's capabilities do not establish installation, batteries or a continuing cloud-service entitlement in the supplied package.
