Dirt and foggy lenses are some of the common problems that can affect the image quality of a camera. When the lens is covered with dust, oil, fingerprints or moisture, it can blur or reduce the clarity of the recorded image. This can prevent the camera from capturing important details, especially in situations that require high precision such as security surveillance or recording in low light conditions.

Causes:

Dust and dirt: Easily adhere to the lens when the camera is used in a dusty environment or is not properly protected. Refer to cleaning instructions on Google
Oil and fingerprints: When the user comes into direct contact with the camera, especially the lens, the oil from the hands can leave traces, causing the lens to fog up.
Moisture: If the camera is used in humid conditions or is not protected from rain or fog, moisture can condense on the lens, reducing visibility.

Solution:

Regular cleaning: Use a soft, lint-free cloth and a specialized cleaning solution to clean the lens. Avoid using paper or rough cloths to wipe, as they can scratch the lens surface.Use a lens cover: Make sure the lens is always protected when not in use to prevent dust and dirt from getting on it.Install in a dry environment: If possible, install the camera in locations that are not directly exposed to dust or high humidity. For outdoor cameras, specialized dust and water-resistant protective covers can be used.Regular inspection: Periodically inspect and clean the camera equipment, especially when the image is unclear or blurry.
