To resolve the video lags or the audio and video are out of sync while viewing the Xiaomi Smart Camera C700's surveillance footage, please refer to the following steps:
1. If the video lags or frequently displays a loading screen, switch the video quality to automatic or smooth mode;
2. If the video and sound are out of sync, check if the camera's network connection is stable. A weak or unstable connection can cause delays. If the delay persists, try exiting and re-entering the surveillance footage.
