To resolve this issue, please refer to the following steps:
1. Ensure that the camera lens is clean and free from dust or smudges. Use a soft, lint-free cloth to gently wipe the lens, as any obstructions can significantly affect image clarity;
2. Examine the camera's surroundings to ensure that the lens is not obstructed by any objects. This includes checking for reflections from nearby surfaces, such as windows or mirrors, and any wall coverings that can interfere with the camera's view. Additionally, point light sources, such as lamps or streetlights, can impact the infrared night vision quality;
3. If you identify any obstructions, adjust the camera's position accordingly. You can tilt or reposition the camera to move the lens out of the obstructed area.
