Build a powerful smart home ecosystem by connecting up to 64 switches, sensors, or buttons plus 4 cameras or video doorbells, allowing seamless integration with compatible devices such as Tapo C420, Tapo C400, Tapo D230, and more. The hub also functions as a smart alarm and chime, working together with your cameras, video doorbells, and sensors to trigger alerts when motion is detected or when a visitor arrives. For secure local storage, recorded videos from connected cameras or doorbells can be saved directly to a hub-installed microSD card with support up to 512 GB, ensuring convenient access without relying solely on cloud storage. Customize your alerts with 19 built-in ringtone options and adjustable volume levels of up to 90 dB, making it easy to create personalized notification scenarios throughout your home. The hub uses an ultra-low power wireless protocol that helps connected smart sensors and buttons last up to 10 times longer, improving overall efficiency and battery life. It also supports voice control through Amazon Alexa and Google Home, enabling hands-free automation and easy management of your smart devices. This device operates in a specified Sub-1G band, so when connecting it to other devices or hubs, ensure they operate within the same Sub-1G frequency band for proper functionality.
