1. Product Overview
The FERMAX VEO-XL WIFI DUOX PLUS kit is a state-of-the-art video intercom system designed for single-family homes, offices, and businesses. It operates on the DUOX PLUS fully digital, two-wire non-polarized technology, simplifying installation while maintaining high product quality and design.
This kit includes the essential components for installation: the CITYLINE outdoor panel, the VEO-XL WIFI monitor, and the necessary power supply. The VEO-XL WIFI monitor features built-in Wi-Fi connectivity, enabling call transfer to mobile devices via the free Fermax DuoxMe app, available on Play Store and App Store. This allows users to manage video intercom functions directly from their smartphone or tablet, including answering calls and remotely opening the door from anywhere.
A key feature is the Photocaller function, which automatically captures an image of the caller. The monitor can store up to 150 images with date and time stamps. Once the maximum capacity is reached, the oldest image is automatically deleted when a new one is taken. The screen indicates if there are unviewed photos or if the date/time is not set.
The VEO-XL WIFI DUOX PLUS monitor is a hands-free, extra-slim unit with a 7-inch (16:9) color wide screen. Its OSD menu and button layout ensure simple and intuitive user interaction. The unit is constructed from high-impact ABS plastic, offering durability and a balanced, modern, and minimalist design.
