Five Skills of Choosing Meeting Cameras

Conference camera is an important part of video conference, lecture hall, video classroom and remote visual terminal. At present, IVCOO (Baifu Evergrande), SONY (Sony), PANASONIC (Canon), NEC and other internationally renowned brands are mainly used in telecommunications, education, government, military and other industries, and are the most widely used products in China.

1, resolution

Resolution is the ability of a camera to analyze and distinguish images. It has a direct impact on the image effect. Generally speaking, the resolution can be divided into photographic resolution and video resolution, that is, the resolution when shooting still images and the resolution when shooting moving images. In the practical application of video conference, the photo resolution is generally higher than the video resolution. The video conference cameras on the market can give different types of resolutions, so it should be noted that some resolution marks refer to the interpolation resolution that these products can achieve by using software, but there is still a certain gap compared with the hardware resolution.

2. Pixels

Pixel value is an important index that affects the quality of video conference camera, and it is also an important symbol to judge its advantages and disadvantages. The pixel value of early products is generally around 654.38+ 10,000. Because of its low technical content, it is on the verge of elimination, so users should pay attention to it when purchasing. But you don't have to blindly consider the pixel value. Because the higher the pixel value, the stronger the product's ability to analyze images and the higher the ability to process data on the computer. If the computer configuration is not high enough, it will delay the picture and affect the transmission of video conference. Therefore, users should consider their own equipment comprehensively when purchasing products, and don't blindly pursue the trend.

Step 3: lens

Lens is an important part of video conference camera. At present, the photosensitive elements of video conference cameras on the market can be divided into CCD and CMOS. The advantages of CMOS are low manufacturing cost and much lower power consumption than CCD. However, due to the immature application technology, it has not been widely used, but most people in the industry think it is the future trend. At present, the dimensions of CCD elements are mostly 1/3 inches or 1/4 inches. Under the same resolution, it is better to choose a larger element size. Because there is a big gap between the video streaming effect of analog camera and CCD camera, users should not choose analog camera cheaply when purchasing, so as to avoid the loss of unnecessary shopping.

Step 4 connect

Without USB interface, high data transmission capability is impossible. However, there will be a lot of data transmission in the actual use of video conference cameras, so users should pay attention to it when purchasing. The high speed of USB data transmission determines the application of video conference camera. The high-speed transmission of USB data breaks the bottleneck of mass data transmission of image files, which makes the computer receive data faster and the playing effect of dynamic images smoother, which is very important to the meeting effect. In addition, USB products have been widely accepted by computer users because of their plug-and-play and easy use. The video conference camera adopts USB interface, which can make its hardware detection and installation more convenient.

5. Transmission bandwidth

At present, high definition is the mainstream trend of video conference promotion. However, it should be noted that to achieve the effect of high definition, the whole high-definition equipment needs to cooperate. It is not enough to configure high-definition cameras and high-definition live-action terminals, and network bandwidth is also one of the important factors. Therefore, users should fully consider their own bandwidth capacity when purchasing HD. If the bandwidth is not enough to support high-definition communication, packet loss will occur, which will affect the conference effect. Standard definition or high definition should be used according to the facts, and must not blindly follow the trend.
