What are the famous brands of domestic surveillance cameras?

Domestic well-known brands:

1. Tiandi Weiye (the unit that drafts national standards for security products)

2. Hikvision (world brand, leading domestic brand) Surveillance brand)

3. Tyco Security (Security Components Global Company, United States)

4. Yaan (the first company in the security industry to be listed overseas)

5. Shenzhen Dizhte (the company with the largest exports in Shenzhen’s security industry)

6. Shenzhen Shixin Electronics (multiple patented technology inventions have allowed it to occupy the high-end position for many years)

7. Qisheng Technology (Qisheng has successfully created its own brand of surveillance cameras, with high cost performance)

8. Dahua Technology (Dahua Technology is based in central China, radiating across the country, with surveillance cameras Military quality, a big brand created by hard products)

9. Fujian Guanlin (a big brand coming out of a small city must be outstanding)

10. Anjubao (a certain security product company that is very successful in trade, industry and technology)

Selection method:

1. Image resolution

When it comes to cameras, you will know The first element that comes to mind is no exception for integrated cameras. A few years ago, most of the better all-in-one computers on the market had image resolutions around 420 lines, and the lowest ones were only 380 lines. As far as practical applications are concerned, a resolution of 480 lines is the most practical.

2. Focusing speed and focusing accuracy

Generally speaking, an integrated camera can be simply regarded as a unit, in which an electric optical zoom lens is installed. , Video signal acquisition and processing control module board, video/power/data control interface and management programming information button interface and other components. Since the first two parts have been uniformly packaged in an aluminum box that is approximately square in size and shape (commonly known as the movement), after the zoom operation is performed on the integrated camera, the machine itself can perform the auto-focus function, and the focusing speed and The quality of accuracy directly affects the user's capture and recording of images from the surveillance site.

3. Optical zoom factor

It is not that the larger the optical zoom factor, the better. When the focal length is short, the image seen is in a wide-angle state, and when the focal length is long, the image is seen in the distance. The magnified state of the object.

4. Low illumination

Since integrated cameras have a relatively wide monitoring range and are mostly used in outdoor environments, they are bound to be affected by changes in outdoor light. With the increasing number of criminal cases in society, as well as people's deepening awareness of security and improving security management levels, users now generally have a need for 24-hour uninterrupted monitoring, especially when the light illumination is insufficient at night. It is necessary to ensure that the all-in-one machine can adapt to low-light shooting environments. In some completely dark situations, infrared lights are even needed, so some manufacturers launch all-in-one machines with infrared sensing capabilities.

5. Selection of movement

At present, the core part of the integrated camera, the movement, is manufactured by foreign manufacturers, and the mainstream movement suppliers on the market Nothing more than SONY, HITACHI, LG and CNB. There are many domestic brands of integrated cameras, and they basically use the movements of these four brands. Low-tech accessories such as casings and back panels are processed and manufactured by the manufacturers themselves. Therefore, the core movement of an integrated camera like this is still an imported product, and the overall quality is still good. When purchasing, just pay attention to meeting your own engineering needs. In addition, some domestic manufacturers have stated that they can produce integrated movements.

6. Functional performance

As the design of integrated camera processing circuits becomes more and more sophisticated, and the degree of digital processing of video signals becomes higher and higher, the functionality of the machine It also gradually became stronger.

7. Color restoration ability
