How do we choose the right video conferencing camera for the video conferencing system?The selection of video conference camera mainly considers the following aspects, namely lens, acquisition pixel, acquisition resolution, control protocol of the cradle head and the corresponding interface...
1. Video conference camera lens
Video conference camera images are collected images through the lens, so the stand or fall of video conference camera will affect the quality of the image acquisition video conference, good video conference cameras will restore good video images, and poor video conference cameras will appear blurred images even partial color, so we in the choice of video conference cameras, the need for field test, to see if video conference camera image is clear and color in partial color.The camera lens of video conferencing camera is the original lens is the best, we should consider the quality of the lens, not only consider the price when we buy.
2. Video conferencing camera captures pixels
The pixel captured by video conferencing camera refers to the pixel value generated by an image captured by the camera. Under the same resolution, the larger the pixel is, the higher the definition of the image will be. Therefore, when choosing video conferencing camera, we should purchase a camera with high pixel under the same conditions.
3. Video conference camera acquisition resolution
Video conference cameras generally divided into the camera, high-definition cameras, full hd camera, high-definition cameras to collect generally refers to more than 720 p resolution, and complete resolution of 1080 p hd video camera acquisition, collection of video conference camera resolution is higher, its core components, the more precise, so the price is higher also.Do we have to choose hd video conferencing cameras or full HD cameras when purchasing video conferencing systems?The answer is no, we cannot assume that the higher the resolution camera is the better, we should combine the video conferencing system project needs to carry out the procurement.If our video conference system is on the public network environment, and the bandwidth of the terminal is lower, if we choose high-definition cameras or full hd video cameras, transmission in the network environment, and video conference cameras will not be able to give full play to their own hd advantage, we might as well choose standard definition video conference camera, so we in the choice of video conference camera, not only consider the acquisition resolution, but also combined with the needs of the project to select the most suitable product video conference cameras.
4. Cradle head control protocol for video conference camera
Video conferencing camera can be connected through THE COM port of PC, and then control the camera through the control protocol of the head, such as the rotation of the camera, focus and so on.The Cloud Platform protocol usually has Visca and Peclo protocols, and general purpose video conferencing cameras support both protocols, so when choosing a video conferencing camera, it is important to consider whether both protocols can be supported.
5. Interface of video conferencing camera
Video conferencing cameras are available with USB ports or without USB ports. Video conferencing cameras without USB ports need to be connected to video capture CARDS via AV or HDMI ports.We can choose the video conferencing camera with USB interface according to the needs of the project. The camera with USB is generally simple to use and can be used directly when connected to PC, but its data bottleneck is affected by USB interface.With the advent of USB3.0, the TRANSMISSION bandwidth of USB has been greatly improved, so the video conferencing camera with USB has gradually become the mainstream product in the market.
To sum up, in the video conferencing system camera procurement, we should comprehensively consider the video conferencing camera lens, acquisition pixel, acquisition resolution, head control protocol and the corresponding interface, and take into consideration the requirements of the project.There is no false belief that the more expensive the video conferencing camera is, the better it will be, knowing that the video conferencing camera suitable for our project is the best choice.
