Is the camera unclear and the optical fiber related?

The reason why the camera is not clear:

1. There is dust on the glass or lens.

2. The focal length of the lens is not adjusted properly.

3. After a long time, the lens holder took shape.

4. Hard disk video recorder or inferior acquisition card

5. Video signal attenuation is too high.

6. Even if the line is bad

7. The low camera chip configuration will also

As a video transmission medium, optical fiber is not clear to the camera.

Definition of optical fiber: Thin optical fiber is encapsulated in a plastic sheath so that it can be bent without breaking. Generally, a transmitting device at one end of an optical fiber uses a light emitting diode (LED) or a laser beam to transmit light pulses to the optical fiber, while a receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses.

Other reasons and solutions:

1. Check the image quality set in the camera. If the setting is low, record low-resolution video. On the camera, there is no difference because of the small screen, but on the computer, it is easy to compare because of the large screen. And the effect originally put on the computer is not as clear as that seen on the camera.

2. Generally, it can be recorded when the outdoor light is good, and the video image will be noisy when the indoor light is bad, and the image will be unclear accordingly.

3. It may be that the original performance of the camera is average and the pixels are low, rather than the quality problem of the machine itself.

4. Whether the camera is analog or digital, if it is digital, the quality of the recorded video file should not be lost; If it is analog tape recording, it will be collected by the acquisition card, of course, there will be a loss of image quality, and the video acquisition card can set the format during the acquisition process, which will also affect the clarity. Also, whether the video editing software supports high-definition acquisition.

Finally, you can check whether the focus position of the image behind the camera is adjusted correctly, whether the focal length of the lens is adjusted correctly, whether the lens surface is clean (if there is dust or fingerprints on the lens, it will definitely affect the image quality), whether the computer monitor is adjusted correctly, and whether the display surface is clear and clean.

The camera should be handled with care and kept clean during use to improve its service life.
