The correct answer is network adaptation . This function is used when live video quality is affected by unstable bandwidth, packet loss, or fluctuating network throughput. In that situation, the camera dynamically adjusts the stream bit rate to match current network conditions so that video transmission remains stable and smooth. The key logic in the question is the phrase that the camera can “adjust the bit rate automatically based on the onsite network status, to ensure smooth live video” , which directly corresponds to adaptive network-side stream control rather than image tuning, PTZ control, or exposure optimization.

From a technical perspective, artifacts and stuttering during live video are often caused by transport limitations rather than by optics or encoding settings alone. Huawei’s live-view framework depends on continuous stream delivery, decoding, and display on the specified window . If the network becomes unstable, fixed-rate transmission may overload available bandwidth. Enabling network adaptation allows the camera to reduce or optimize the bit rate in real time, which improves continuity and reduces playback interruptions. Therefore, network adaptation is the correct function to enable.
