The IdeaHub S2 camera uses a 4P+4G (4 Plastic + 4 Glass) hybrid lens design. Glass elements provide superior optical clarity and heat resistance, while plastic elements allow for precision aspherical shaping. This hybrid construction is specifically tested to withstand extreme environmental conditions from -20°C to 70°C .
This ensures that the lens does not deform, fog, or lose focus even if the device is transported in freezing conditions or installed in environments with significant heat buildup.

The Huawei IdeaHub S2 leverages powerful AI computing capabilities to enhance the meeting experience through three primary "Intelligent" features:
* Acoustic Baffle (B): Uses AI to create a virtual sound fence. It picks up only the voices within the defined "frame" of the camera and filters out all noises or conversations happening outside that area.
* Voice Tracking (C): The AI-powered camera system can identify who is speaking in the room and automatically zoom in/center the shot on that specific person to ensure they are the focus of the meeting.
* Auto-Framing (D): The system uses facial recognition and body detection to automatically adjust the camera's field of view so that all participants in the room are perfectly centered and optimally displayed.
Multi-window (A) is a productivity feature of the HarmonyOS platform that allows for multitasking (opening two apps side-by-side), but it is categorized as a UI/Smart Office feature rather than an "AI Meeting" function.

The SMC serves as the "brain" of the Huawei Intelligent Collaboration solution.
* Option A is correct: It supports various networking scales, from single-node lightweight deployments to multi-level, large-capacity hierarchical networking for global enterprises.
* Option B is correct: It provides comprehensive control features, including extending conferences, inviting participants, switching continuous presence, and managing chair rights.
* Option C is correct: Huawei provides RESTful APIs for the SMC, allowing third-party developers to integrate video conferencing functions into their own office automation (OA) systems or apps.
* Option D is incorrect: While the SMC manages and initiates recording tasks, the actual technical capability to record and stream 1080p@60 fps dual-stream video is a feature of the CloudRSE (Recording & Streaming Engine), not the SMC itself.

The Huawei CloudLink Bar 310 is an industry-standard terminal designed for maximum interoperability. It supports the two primary signaling protocols: H.323 (B) and SIP (D) .
To facilitate content sharing (dual-stream) during a call, it supports the corresponding data protocols for each signaling type:
* H.239 (A): The standard for dual-streaming within H.323 calls.
* BFCP (C): The Binary Floor Control Protocol used for dual-streaming within SIP calls.
This ensures the Bar 310 can share presentations and video simultaneously regardless of the infrastructure it is connected to.

Huawei provides an Open SDK for the IdeaHub to allow third-party developers to integrate their own office or industry-specific applications. For "lightweight integration," the SDK allows these apps to invoke the IdeaHub's professional-grade camera and microphone hardware. The standard performance target for these third-party integrations is 1080p HD video , providing a professional conferencing experience even when using non-native apps. While deep hardware optimization (as seen with Huawei's own WeLink or Cloud Meeting) can push certain capabilities higher, 1080p is the verified standard for lightweight integrated remote meetings.
