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.

Excellent Watch
Color: Gold Silver-G8408
I don't know why this watch is getting a less than perfect rating from others. I purchased this watch legit to make sure my son got out of the shower at the gym on time to get where he is going. LOL It is classy, elegant and yes, has been exposed to sweat, water and soap extensively, and still looks fantastic. He is getting the black one next.

looks good but is unreliable; replacement coming
Color: Gold Blue-G8408
Update: The company reached out to me and offered me either a refund or a replacement watch. I bumped my rating up by two stars for that good customer service, and I'll provide another update once I have the replacement and see how it works. This watch looks great, was a good price, and I enjoy wearing it. The problem is that it keeps stopping. An unreliable watch is a big problem. Unfortunately, I was out of the country and didn't get to return it in time before the return window closed. If it worked properly, I would have given it a five-star rating.
