The security camera is not clear

Now most people will install surveillance cameras, in order to home or work place security, some surveillance cameras will feel blurred after a period of time, do you know what is the reason?

Why is the surveillance camera not clear?

Old surveillance cameras become blurred after being used for a long time, which is caused by a variety of reasons. Specific problems are analyzed in detail. There are mainly the following situations that will lead to unclear cameras:

1. The dust

Over time, the outer layer of the lens is covered with dust, resulting in confusion. We can wipe the dust on the mirror cloth with a soft cloth.

2. The atomization

Some cameras because the work is not very precise, in the environment is not good or outdoor, there is rain penetration into the camera inside, over a long time, will form a layer of foggy in the lens, which will lead to the camera can not see clearly.

Treatment methods:

Remove the lens in front of the lens, dry the "fog water" with a hair dryer, and then wipe it clean.

3. Chip aging

The camera works 24 hours a day, and the monitoring head of the second and third tier brands will work for a long time, which will lead to chip aging and unable to resolve the pixels of the lens, resulting in confusion. In this case, we can only change the camera.

4. The lens is out of focus

The lens is loose, the focal length is not correct, resulting in the camera can not see clearly. Remove the lens and adjust the focal length.
