Why the camera takes pictures is unknown. It used to be clear.

Long-term use will lead to equipment aging, try to restore the factory settings.

Cause analysis:

1. The lens is dirty with dust.

2. Insufficient light

3. The camera pixel is low

4. Camera focal length adjustment problem

Simple steps:

Wipe the lens-improve the lighting environment-adjust the focal length of the camera-replace the camera with higher pixels.

Solution:

Camera video blur is usually caused by the following reasons:

1. Dirty camera lens: To ensure the camera lens is clean, here is a trick: first squeeze a small amount of toothpaste on the lens, tear off a small piece of cotton, and smear the toothpaste evenly (at this time, you will see that the lens is getting blurred, don't worry, continue to look down). After applying evenly, quickly and repeatedly wipe the place where toothpaste has just been applied with another clean cotton, so that the lens will be clear.

2. Poor lighting in the use environment: You need to adjust the use environment of the camera to get enough light.

3. The camera itself has low pixels: change to a camera with higher pixels.

4. The focal length of the camera is not properly adjusted (some cameras can manually adjust the focal length, as shown in figure 1: the focal length can be adjusted by rotating left and right).
