Does the Xiaomi Smart Camera C500 Pro support two-way voice calls?

Yes. The Xiaomi Smart Camera C500 Pro supports two-way voice calls. It uses active noise cancellation technology to eliminate speaker echoes and effectively improve the call experience. This means you can not only listen to audio captured by the camera but also speak through the camera by connecting to the Mi Home/Xiaomi Home APP. This feature enables you to communicate with people near the camera's location, which can be useful for various purposes including monitoring, security, or even interacting with family members or pets remotely.
