How Do We Buy Video Conferencing Cameras
May 24, 2022
With the popularity of video conference, the role of video conference camera in video conference is becoming more and more important, but do you really know video conference camera?
Generally speaking, what kind of conference camera should be selected depends on the specific application. For example, whether to take in the plenary session during video conference? Would you like a close-up of the speaker? SD or HD? How big is the meeting room? Do you want to celling/wall mount?
These basic needs to be determined before comparing the price, appearance and performance parameters. The camera can be inspected from the following parameters. The main factors are: 1 Pixel 2 Lens 3 Interface 4 Resolution 5 Transmission speed.
1. Video conference camera lens
The image of the video conference camera is collected through its lens. Therefore, the quality of the video conference camera lens will affect the quality of the image collected by the video conference. The lens of a good video conference camera will restore a better video image, while the lens of a poor video conference camera will have image blur or even color deviation. Therefore, we need to conduct field testing when selecting the video conference camera, Check whether the video conference camera image is clear and whether the color is biased.
2. Video conference camera capture pixels
The pixel collected by video conference camera refers to the pixel value generated by the camera collecting an image. Under the same resolution, the larger the pixel, the higher the definition of the image. Therefore, when selecting video conference camera, we should purchase a camera with high pixel under the same conditions.
3. Video conference camera acquisition resolution
Video conference cameras are generally divided into standard definition cameras, high-definition cameras and full high-definition cameras. The acquisition resolution of high-definition cameras generally refers to more than 720p, while the acquisition resolution of full high-definition cameras reaches 1080p. The higher the acquisition resolution of video conference cameras, the more precise their core components are. Therefore, when selecting video conference cameras, we cannot only consider their acquisition resolution, We should also select the most appropriate video conference camera products according to the needs of the project.
4. Interface of video conference camera
The video conference camera has USB interface and multi interface. We can choose whether to use the video conference camera with USB interface according to the needs of the project. The camera with USB is generally simple to use and can be used directly connected to the PC, but its data bottleneck is affected by the USB interface. Multi interface cameras are not affected by the site and interface mode. So we should choose according to our own needs.
5. PTZ control protocol for video conference camera
The video conference camera can be connected through the COM port of PC, and then the camera can be controlled through PTZ control protocol, such as camera rotation, focusing, etc. PTZ protocols usually include visca protocol and peclo protocol, and general video conference cameras will support these two protocols. Therefore, when selecting video conference cameras, we should mainly focus on whether these two protocols can be supported.
Under the guidance of the tide of informatization, the application planning of video conference is becoming more and more extensive. It has begun to be used in simple professional fields and expanded to broader consumer malls. In a complete video conference system, the application effect of conference camera directly determines the quality of the conference.
In conclusion, in the camera procurement of video conference system, we should comprehensively consider the lens, acquisition pixels, acquisition resolution, PTZ control protocol and corresponding interfaces of video conference camera, and consider them in combination with the needs of the project. There should be no misunderstanding that the more expensive the video conference camera, the better the effect will be. We should know that the video conference camera suitable for our project is the best choice.
