Several factors will lead to blurry images or no images on the videos recorded by the Xiaomi Smart Camera C300 Dual in night-vision mode, such as inadequate lighting conditions or lens performance. Additionally, motion blur can occur if subjects are moving quickly, and infrared light used for night vision will not provide enough detail.
If you meet the issue, please refer to the following details:
1. Please make sure the camera lens is clean and dust-free;
2. Please check whether the lens is blocked by debris. If so, please rotate the PTZ or move the camera position in the Mi Home/Xiaomi Home APP to move the lens out of the blocked area.
