This is the TP-Link Smart Hub H500. Although it's not released in Japan, it has passed Japanese technical standards compliance (confirmed on the Ministry of Internal Affairs and Communications website), and the AC adapter has a PSE mark. It can connect 64 sensors + 16 Tapo cameras, and you can save up to 16TB of camera footage in a local environment without subscribing to a paid cloud service. (SSD/HDD sold separately) It also has an HDMI output, allowing you to constantly check camera footage on a TV or monitor, and it has built-in AI that improves the recognition accuracy of cars, people, animals, etc. Tapo cameras store data on internal SD cards, so you needed a cloud subscription considering camera theft, etc. However, I didn't want to upload data to the cloud due to the annual cost of around 10,000 yen and recent security issues, so I somehow purchased two units, one for my home and one for relatives. But! My relatives couldn't use it, so it was returned unused. (The third image is the one I use at home; the item for sale is unopened) It's quite a bargain, as you can build a local environment + upgrade features (AI recognition, doorbell integration, etc.) with the initial cost of several years of subscription fees. ■Product Description (excerpt)■ ・Tapo H500 connects and controls up to 16 Tapo cameras and 64 Tapo sub-G sensors, integrating smart home IoT devices into a single platform. ・In addition to 16GB of internal storage, it supports unlimited additional storage via a 2.5-inch SATA HDD/SSD (power supply 5V/maximum operating wattage 10W, sold separately).
