The ZKTeco VEX-B21L is a smart outdoor video station for entrances that need visitor intercom, IC card access, NFC access and PIN verification in one unit. It is well suited to apartments, offices, gated entries and commercial sites where a clean video intercom and door release solution is required.
The ZKTeco VEX-B21L is designed for entry points where video communication and access control need to work together. It combines a smart outdoor video station, IC card access, NFC access and PIN verification in a flush-mounted unit.
For apartment buildings, office entrances, gated pedestrian access and commercial sites, the VEX-B21L gives users a practical way to verify visitors through compatible indoor monitors before granting access.
The 2MP CMOS camera, 720p video resolution and H.264 codec support clear video communication at the entrance.
Supports IC card, NFC and PIN code access, giving sites practical options for residents, staff or authorised users.
Supports SIP 2.0 and ONVIF, with RS485, Wiegand and Ethernet connectivity for compatible intercom and access control environments.
The VEX-B21L is a strong fit for sites that need a tidy outdoor intercom station with straightforward access control features. It is especially useful where a full keypad, display, card access and visitor communication are required at the same entrance point.
The VEX-B21L supports two-way communication with visitors via compatible indoor monitors, helping users confirm who is at the entrance before unlocking. It can also control the main door unlock and integrate with elevator control systems where supported by the wider system design.
With an aluminium front panel, IP65 water and dust resistance, and an operating temperature range from -40°C to +55°C, the VEX-B21L is built for demanding outdoor access points. Its flush-mount design provides a cleaner finish for modern building entrances.
