Advanced Access Control and Smart Video Intercom Solution

Introducing the ZKTeco VEX-B21A, a sophisticated and robust IP-based outdoor video intercom station designed for modern buildings. This powerful console operates on an Android OS, seamlessly integrating high-definition video communication with advanced facial recognition for a comprehensive access control solution. It offers multiple verification methods, including facial recognition, IC card, PIN code, and mobile NFC, providing flexibility and enhanced security for any entry point. The VEX-B21A is engineered for outdoor environments, featuring a durable aluminum front panel and an IP65 rating for water and dust resistance.

Crystal-Clear Imaging and Communication

The integrated 2MP CMOS camera captures sharp, clear images with a wide 100° viewing angle, ensuring you never miss a detail. A white LED supplement light and IR sensor provide excellent visibility in all lighting conditions, day or night. The system facilitates two-way audio communication with indoor monitors, allowing for clear verification of visitors before granting access. It supports the SIP 2.0 protocol for easy integration with other SIP-enabled devices and H.264 video codec for efficient, high-quality video transmission.

Seamless Integration and Versatile Connectivity

The VEX-B21A is designed for complete system integration. It is equipped with a relay and an RS-485 port, allowing it to directly control door locks and connect with other access control devices. Additional ports for an exit button, door magnetic sensor, and Wiegand mean it can serve as the central hub of a comprehensive security setup. Powering the device is simple with options for either PoE (IEEE802.3af) or a standard DC 12V supply.

Junk!
Color: 3675 ALL Silver
Good luck getting the back plate back in once you change the battery! You get what you pay for so spend the extra money and buy a better watch not made in China.
