What To Consider When Purchasing A Video Conferencing Camera

What to consider when purchasing a video conferencing camera

As a common video device, the camera will continue to evolve and develop rapidly with the video. The camera is also widely used in video conferencing and other aspects, and the camera is gradually gaining the favor of enterprises and individuals. There are too many brands of cameras, the difference in practical effects, and the performance of the products are also uneven. Therefore, how to choose the appropriate video conference camera becomes a key factor in the use of video conferencing. Choosing a good camera should focus on the following parameters:

First, the lens:

The lens is an important part of the camera, and the photosensitive elements of the camera can be divided into CCD and CMOS. CCD (Charge Coupled Device) is a high-end technical component used in photographic imaging. CMOS (Complementary Metal-Oxide Semiconductor) is used in products with lower image quality. Its advantage is that the manufacturing cost is higher than that of CCD. Low, power consumption is also much lower, which is why many products using USB interface do not need external power supply. At present, the size of the CCD component is usually 1/3 inch or 1/4 inch. At the same resolution, it is preferable to select a larger component size. Since the video stream effect of the analog camera is quite different from that of the CCD camera, it is not necessary to choose an analog camera cheaply.

Second, the pixel:

Pixel value is an important target that affects the quality of the camera, and it is also an important symbol to judge the quality of the comparison. The pixel value of the product launched in the early stage is usually around 100,000. Due to the low technical content, it is now at the margin of screening. Today's mainstream products usually have a pixel value of around 350,000. It is not necessary to think about pixel values blindly. The higher the pixel value, the stronger the ability of the parsed image of the product. Therefore, when the camera is working, the computer needs to process the data, and the demand for the image is delayed, and then the video is affected. The transmission of the meeting.

Third, the resolution:

The resolution is the ability of the camera to resolve the image. Of course, it is directly related to the quality of CCD/CMOS. Generally, it can be divided into two types: photo resolution and video resolution, that is, the resolution at the time of still picture capture and the resolution at the time of dynamic picture capture. In the actual use of video conferencing, the photo resolution is generally higher than the video resolution. The types of resolutions that can be given by cameras on the market are also different, so you should pay attention when purchasing. Some resolutions refer to the interpolation resolution that these products can reach using software, but they are distinguished from the hardware. The rate comparison still has a certain distance.

Fourth, the transmission speed:

The video capture of the camera is one of the camera's central functions. At present, the video capture of the camera is realized by software, so the demand for CPU disposal is also high, because the screen demand and capture can be directly proportional. Now the maximum resolution of the camera captured by the general camera is 640×480. Under this resolution, no camera can reach the capture of 30 frames/second, so the picture will be beaten. The actual comparison is that under the 320×240 resolution, relying on the combination of hardware and software, there is a capture index that can reach the specification rate, so for a complete video capture speed, there is only one theoretical indicator. Therefore, the user probably chooses the right product according to his or her own needs to reach the intended effect of the video conference.

Fifth, the interface:

High data transfer volume, no USB interface can not be served. USB port products have always been plug-and-play, easy to use and willing to be accepted by a wide range of computer users. The choice of USB interface not only makes the camera hardware detection and device comparison convenient, but more importantly, because the high speed of USB data transmission determines the use of the camera, it breaks the bottleneck of large data transmission of image files, and makes the computer receive data more. Agile, making the playback of dynamic images smoother and more circulated.
