The ZKTeco VEX-B21A is a smart outdoor video station for entrances that need video intercom, facial recognition, IC card, NFC and PIN verification in one unit. It is designed for apartments, offices, gated entrances and commercial access points where visitor verification and flexible unlocking methods are important.
The ZKTeco VEX-B21A combines video intercom, facial recognition and access control in a flush-mounted outdoor station. It gives residents, staff or authorised users multiple ways to unlock, while still allowing visitor communication through compatible indoor monitors.
For apartments, office entrances and gated pedestrian access points, the VEX-B21A is a practical option where a standard keypad or card reader is not enough. Facial recognition, IC card, NFC and PIN verification provide flexibility for different user groups and site requirements.
Supports facial recognition for door unlocking, with capacity for up to 10,000 face templates.
The 2MP CMOS camera, H.264 codec and 1080p video support help users visually verify visitors before granting access.
Supports facial recognition, IC card, NFC and PIN code access, giving sites more ways to manage authorised entry.
The VEX-B21A is suited to entrances where visitor communication and access control need to work together. It is particularly useful for sites wanting contactless facial recognition alongside traditional credential options.
Two-way communication through compatible indoor monitors allows users to verify visitors before unlocking. The relay output, RS485 and Wiegand connectivity also make the VEX-B21A practical for access control environments where the outdoor station needs to connect with door locks and compatible devices.
The aluminium front panel, IP65 water and dust resistance, and -40°C to +55°C operating temperature range make the VEX-B21A suitable for demanding outdoor entry points. Its flush-mount design provides a clean, professional finish for modern building entrances.
