Tenveo tell you how to choose a high-definition video conferencing camera
With the continuous progress of remote video communications and the development of video conferencing camera types are diversified, for ordinary end users, choose a suitable, cost-effective high-definition video conferencing camera is particularly important.
Then from the lens, pixel, resolution, transmission speed, transmission interface, these aspects to give you a description and explain.
Lens
Lens is an important part of the camera, the camera's sensor can be divided into CCD and CMOS. CCD (Charge Coupled Device) is a high-end technology component for photographic imaging. CMOS (Complementary Metal-Oxide Semiconductor) is used in low image quality products. Manufacturing costs lower than the CCD, power consumption is also much lower, which is the market a lot of USB interface products without external power supply reasons. At present, the size of CCD components is more than 1/3 inch or 1/4 inch, at the same resolution, it is appropriate to select the larger component size.
Pixels
Pixel value is an important indicator of the quality of the camera, but also to determine the merits of the more important signs. Early introduction of the product pixel value is generally around 10 million, because the technical content is not high, it is now in the elimination of the edge. Now the mainstream product of its pixel value is generally around 35 million. It is not necessary to think about pixel values. Because the higher the pixel value of the product its ability to parse the image the stronger, so that when the camera to work, the computer data processing capacity is also demanding, otherwise it will cause the screen delay, which affected the video The transfer of the meeting.
Resolution
Resolution is the ability of the camera to resolve the image. Of course, its and CCD / CMOS is a good relationship is good or bad. Generally can be divided into camera resolution and video resolution of two, that is, static screen capture resolution and dynamic picture capture resolution. In the practical application of video conferencing, the general image resolution is higher than the video resolution. The camera can give the type of resolution is not the same, so you should pay attention when buying, some resolution of the logo is that these products can use the software to achieve the interpolation resolution, but the hardware resolution Rate or still have a certain gap. In the case of
transfer speed
Camera video capture capability is one of the core functions of the camera. Video capture of the current camera is achieved through the software, so the CPU processing capacity requirements are higher, because the screen requirements and capture capacity is proportional to. Now the general camera to capture the maximum resolution of the screen 1920 × 1080, in this resolution can reach 60 frames / sec capture effect, but the greater the resolution of the bandwidth requirements are greater, then this time the user can Consider the choice down, 1280 × 720,720 × 576 so the user should be based on their needs, select the appropriate product to achieve the desired effect of video conferencing. In the case of
Interface
High data transfer, no USB interface is not competent. USB port products have always been plug and play, easy to use and willing to be the majority of computer users to accept. USB interface, not only makes the camera hardware detection, installation more convenient, more important is due to the high speed USB data transmission determines the application of the camera, better break the image file a lot of data transmission bottlenecks, making the computer to receive data more Quickly, so that the dynamic image of the broadcast effect is more smooth and smooth. Now USB3.0 transmission HD video conferencing camera 1080P picture quality can reach 30 frames per second.
Camera selection:
Video conferencing cameras need to be used with video capture cards. The camera is a video conferencing system core equipment, according to user requirements, a reasonable choice is very important. Now the system generally use CMOS camera, because it is compared with the vacuum tube camera has a small size, light weight; inert small; high sensitivity; image uniformity good; good impact resistance; long life and other advantages.
