How To Select A Suitable Video Conference Camera

How to select a suitable video conference camera

Video conferencing cameras, as the most important collection devices for video conferencing, play an important role in the selection of video conferencing hardware devices. Videoconferencing cameras, as a professional conference collection device, have different parameters from other general home cameras. The parameters can often determine the product features of the video conferencing camera. Let's start with the parameters of several video conferencing cameras, and analyze the parameters that need to be paid attention to when purchasing video conferencing cameras:

1, the lens

The lens is a key component of video conferencing cameras. The photosensitive elements selected for the lenses of video conferencing cameras on the market today can be classified into CCD and CMOS. The advantage of CMOS is that the cost is lower than that of CCD, and the power consumption is much lower. However, due to the inexperienced use of technology, it has not been widely used, but the advanced nature determines its future trend. At present, the size of the CCD sensor is usually 1/3 inch or 1/4 inch. At the same resolution, it is better to select a larger component.

Since the video stream of the mimic camera has a large interval compared with the camera of the CCD, the user does not have to choose a mimic camera to avoid the loss of the use of the purchase object.

2, focal length

The focal length is the interval between the point that can be adjusted and the camera. The focal length is large, and the interval between photographing can be far. Under normal circumstances, the video conference camera with fixed focus will be lower than the camera with focusing. The larger the focal length, the farther the guideline can be seen by the camera, and the smaller the focal length, the closer the guideline will be.

3, the resolution of the picture

The resolution of the picture is the ability of the camera to resolve the picture. It has a direct impact on the role of the picture. The resolution can be generally divided into two types: picture resolution and video resolution, which is the resolution during static picture capture and the resolution when moving pictures are captured. In the practical use of video conferencing, the resolution of the picture is generally higher than the resolution of the video.

The variety of resolutions that can be given by video conferencing cameras on the market is also different, so pay attention to the time of purchase. 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 interval.

4, the collected pixels

The pixel value collected by the camera is an important target that affects the quality of the video conferencing camera, and is also an important indicator for judging its quality. The pixel values of the products introduced in the early days are generally around 100,000. Due to the low technical content, they are now at the margin of screening, and users should pay attention to them when purchasing. However, it is not necessary to consider the pixel value blindly. The higher the pixel value, the stronger the ability of the product to parse the image, and the higher the ability to process the data on the computer.

If the computer equipment is not high enough, using high-pixel collection equipment may cause a delay in the picture, and then affect the transmission of the video conference. Therefore, users should summarize their own practical needs when purchasing products, and do not blindly seek trends.

5, transmission interface

It is not enough to collect high-quality pictures by video conferencing cameras. We also need high-speed transmission interfaces to transmit the collected data. If the interface bandwidth used by us is less, the data will be blocked or even skipped. In the practice of video conferencing cameras, there will be a large amount of data transmission, which should be paid attention to when purchasing. USB interface products have been widely accepted for plug and play and ease of use. The video conference camera uses USB interface and can be plug and play. However, because some devices use a lower version of USB, the transmission interface cannot adapt to larger picture data. Therefore, we must publish the USB version when we purchase. And transmission bandwidth.
