Smart living begins here with up to 64 intelligent sensors, buttons, or switches, as well as 4 cameras or video doorbells that are connected to your smart home ecosystem. Use the hub as a smart alarm or chime to protect your home by coordinating it with your Tapo smart cameras, video doorbells, sensors, switches, and more. Store recorded videos from your smart cameras and video doorbells on a microSD card (up to 512 GB) so you never miss a thing. A wireless protocol with extremely low power consumption extends the battery life of devices by up to 10 times.
