Video conference camera selection suggestions
Under the guidance of the trend of informatization, the scope of application of videoconferencing has become more and more widespread, and there has been an initial expansion of the use of specialized fields to a broader consumer market. In a complete video conference system, the application effect of the conference camera directly determines the quality of the conference. However, as a professional product, the general public has limited understanding of the conference camera. Therefore, most users are not only unaware of the choice of products, but also do nothing about some common problems.
As far as the camera is concerned, it is divided into photosensitive elements. Currently, there are mainly CCD and CMOS types on the market. In summary, the cost and power consumption of CMOS-based products are relatively low, which is why many USB-based products in the market do not require an external power supply, but CCD is superior in image quality. At present, the dimensions of the CCD device are mostly 1/3 inch or 1/4 inch. At the same resolution, it is better to select a larger device size.
In the actual purchase, users often think that the higher the pixel of the camera, the better. In fact, this idea is too one-sided. It is undeniable that the pixel value is an important index that affects the quality of the camera, and it is also an important indicator for judging its merits. However, users should be aware that the higher the pixel value, the stronger the ability to analyze images. In this way, when the camera is working, the ability of the computer to process data is also required to be high, otherwise it will cause the delay of the picture, thus affecting the transmission of the video conference.
In practical applications of videoconferencing, the camera resolution is generally higher than the video resolution. The type of resolution that the camera can give on the market is not the same, so users should pay attention to the time of purchase. The resolution of some resolutions refers to the interpolation resolution that these products can achieve with the software, but it is different from the hardware resolution. There is still a certain gap between the rates.
