Brand of conference camera, how to choose conference camera

With the continuous development of science and technology, many companies and self-taught schools are using conference cameras today. Conference cameras are mainly used in video conferences, hospitals, sanatoriums, lecture halls, remote employment, business exchanges, multimedia video classrooms and so on. Use the existing network to meet various market demands such as remote project meeting, remote training, business exchange, video employment, personnel education, etc. Next, let's make a small series to explain the brand of conference cameras and how to buy them.

Conference camera brand

How to buy conference cameras

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 photography resolution and video resolution, that is, the resolution of still image hunting and the resolution of dynamic image hunting. In the practical application of video conference, the photo resolution is generally slightly higher than the video resolution.

The types of resolutions available for video conference cameras on the market are not exactly the same, 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 the most important index that negatively affects the quality of video conference camera, and it is also the most important symbol to distinguish its advantages and disadvantages. The pixel value of products sold in the later period is generally around 654.38+ 10,000. Due to the low technical content, it is now on the verge of elimination, so users should pay attention to it when purchasing. But it also avoids blindly considering pixel values. Because the larger the pixel value, the stronger the product's ability to analyze images and the higher the computer's ability to process data.

Step 3: lens

The lens is the most important part of the video conference camera. At present, the photosensitive elements of video conference cameras on the market can be divided into CCD and CMOS. CMOS has the advantages of lower production cost and much lower power consumption than CCD, but it has not been widely used because of its immature application technology, but many people in the industry point out that this is the future trend. At present, the dimensions of CCD elements are mostly 1/3 inches or 1/4 inches. In the case of the same resolution, it is best to choose a fairly large element size freely. Because there is a considerable gap between the video streaming effects of analog cameras and CCD cameras, users should not choose analog cameras at will for the sake of cheapness, so as to avoid unnecessary shopping losses.

4. Components

Without HDMI module, high transmission capacity is impossible. However, the video conference camera will have a lot of transmission in actual use, so users should pay attention to it when purchasing. The high speed of HDMI transmission requires the application of video conference camera. The high-speed transmission of HDMI data exceeds the bottleneck of mass transmission of image files, which makes the computer receive data faster and the playing effect of dynamic images smoother and simpler, which is very important for the conference effect. In addition, HDMI port products have been widely accepted by computer users because of their plug-and-play and easy use. The video conference camera adopts HDMI module, which can make its hardware inspection and installation more convenient.

5. Transmission bit rate

At present, high definition is the mainstream trend of video conferencing. However, it must be noted that to achieve the effect of high definition, the whole high-definition electronic equipment needs to cooperate, that is to say, it is not enough to equip only with high-definition cameras and high-definition real terminals, and network bandwidth is also one of the most important factors.

Therefore, users should fully consider their own bit rate ability when purchasing HD. If the bit rate is enough to support the wide spread of high definition, packet loss will often occur, which will have a negative impact on the conference effect. Standard definition or high definition should be used according to the facts, and you can't blindly follow the trend.

Editor's summary: That's enough about the brand of conference cameras and how to buy them. I hope I can help you. If you want to know more about it, you can pay attention to the network information. Heart of the King 2 Click on the demo.
