Does the Xiaomi Smart Camera C500 Pro support the NAS transfer storage function?

Yes. The NAS function needs to be used with a MicroSD card, which can transfer and save historical videos on the card. The NAS (Network Attached Storage) transfer storage function refers to the capability of a device, such as a camera or a DVR (Digital Video Recorder), to save recorded data directly onto a NAS device rather than on internal storage or a memory card. NAS devices are specialized storage systems that are connected to a network and provide centralized storage accessible by multiple devices.
