The TP-Link Tapo H200 is the hub that ties a Tapo smart-home and security setup together. It connects up to 64 Tapo Sub-1G sensors, buttons or switches, plus up to 4 compatible Tapo cameras or video doorbells such as the Tapo C420, C400 and D230. Sub-1G is a low-power wireless link that TP-Link says helps battery sensors last up to ten times longer than Wi-Fi devices. The hub doubles as a smart alarm and chime: when a camera picks up motion or a visitor presses the doorbell, it can sound one of 19 built-in ringtones or sirens at up to 90dB. A microSD slot (cards up to 512GB, sold separately) stores recordings from linked battery cameras and doorbells locally, with no cloud subscription. It runs on 2.4GHz Wi-Fi or a wired Ethernet connection, is set up in the Tapo app, and works with Amazon Alexa and Google Home. In the box are the Tapo H200 hub, an RJ45 Ethernet cable, a power adapter and a quick start guide.
