How To Choose HD Video Conference Camera

How to choose HD video conference camera

With the continuous progress and development of remote video communications, the types of video conferencing camera are also diversified. For ordinary end users, it is particularly important to select a suitable, cost-effective high-definition video conferencing camera.

Then from the lens, pixel, resolution, transmission speed, transmission interface, to give you an explanation and explanation.

Lens:

The camera lens is an important part of the camera, the camera's photosensitive elements can be divided into CCD and CMOS. CCD (Charge Coupled Device) is a high-end technology component used in photographic imaging, and CMOS (Complementary Metal-Oxide Semiconductor) is used in a lower image quality product. Its advantages are: The manufacturing cost is lower than the CCD and the power consumption is much lower. This is also the reason why many products using the USB interface do not require external power supply. 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.

Pixels:

The pixel value is an important indicator that affects the quality of the camera, and it is also an important indicator of its merits. The pixel value of the early launch of the product is generally about 100,000. Due to the low technical content, it is now at the edge of elimination. At present, the pixel value of mainstream products is generally about 350,000. It is also not necessary to consider pixel values blindly. Because the higher the pixel value of the product's ability to parse the image is stronger, so that when the camera is working, the computer's ability to perform data processing is also required to be higher, otherwise it will cause the delay of the picture, thus affecting the video Transmission of the conference.

Resolution:

Resolution is the ability of the camera to resolve the image. Of course, it is directly related to the quality of CCD/CMOS. Can generally be divided into two kinds of camera resolution and video resolution, which is the resolution of the static screen capture and the resolution of the dynamic screen capture. In practical applications of videoconferencing, it is generally the camera resolution higher than the video resolution. The type of resolution that the camera can give in the market is not the same, so you should pay attention to the time of purchase. The resolution of some resolution refers to the interpolation resolution that these products can use to achieve the software, but it is different from the hardware resolution. There is still a certain gap between the rates. The

Transfer speed:

The video capture capability of the camera is one of the camera's core functions. At present, video capture of cameras is implemented by software, and thus the processing capability of the CPU is also higher, because the requirement for the picture is directly proportional to the capture capability. Now the maximum resolution of a typical camera capture screen is 1920×1080. In this resolution, the camera can achieve a capture effect of 60 frames per second. However, the higher the resolution, the greater the bandwidth requirement, and this time the user can Consider the downward selection, 1280 × 720, 720 × 576 so users should choose the right product according to their needs in order to achieve the desired effect of video conferencing. 

The interfaces:

High data transmission volume, no USB interface is incompetent. USB port products have always been plug and play, easy to use and willing to be accepted by the majority of computer users. Adopting the USB interface not only makes the hardware detection and installation of the camera more convenient, but also because the high speed of the USB data transmission determines the application of the camera, which effectively breaks the bottleneck of large-scale data transmission of the image file and makes the computer receive data more. Rapidly, the broadcast effect of motion pictures is smoother and smoother. Now the quality of the USB3.0 HD video conferencing camera 1080P can reach 30 frames per second.

Camera selection:

Video conference cameras need to work with video capture cards. The camera is the core equipment of the video conference system. According to user requirements, reasonable selection is very important. Nowadays, the system generally uses CMOS cameras because it is smaller and lighter than a vacuum tube camera; it has less inertia, high sensitivity, good image uniformity, good impact resistance, and long life.
