The Tuya-based Wi-Fi video intercom system with 1080p resolution and a 7-inch monitor is designed for multi-family homes with up to three apartments. It combines traditional door communication with modern smart home integration, allowing for flexible use both locally on the monitor and remotely via mobile devices. The Full HD (1080p) image quality provides a sufficiently sharp and detailed picture for identifying visitors. Combined with the integrated infrared night vision mode, monitoring remains reliable even in low-light conditions, with facial features and movements still clearly recognizable. This increases security, especially in entrance areas with insufficient lighting. The 7-inch monitor offers a clear display and is well-suited for use in multi-family homes. The user interface is functionally designed and allows quick access to key functions such as door unlocking, camera view, and intercom communication. Support for up to three apartments makes the system particularly attractive for smaller residential complexes. The integrated two-way audio function ensures direct communication between residents and visitors. Voice transmission is clear and intelligible, with background noise typically filtered effectively. This enhances its practicality in everyday life, especially during package deliveries or when unexpected visitors arrive. Tuya integration expands the system with smart home functionalities. Users can receive real-time notifications, view live images on mobile devices, and control the system remotely. However, this requires a stable Wi-Fi connection to guarantee lag-free communication. Overall, this video intercom system offers a balanced combination of security, convenience, and modern connectivity. It is particularly well-suited for small apartment buildings or residential complexes seeking a flexible yet cost-effective access control solution.
