This home gateway (HGW) works as a hub for IoT devices including sensors. The HGW has features such as: 1) Design: as the HGW will be used in a living room, it has a minimal cylindrical design conveying a sense of quality. 2) Camera: built into the HGW is a wide-angle camera. It also has a rotary cover that physically blocks the camera to prevent hacking. 3) Voice control: the HGW allows users to control IoT devices naturally with their voice and gives them responses and statuses with speech and light. 4) Bluetooth speaker: the HGW has a speaker box with high sound quality, which serves as an audio speaker.
