What the editor brings to you today is how to distinguish the quality of conference cameras
1. Distinguish the use environment
Generally speaking, there are two kinds of environmental scenes: indoor and outdoor. But in these two environments, there are many factors that affect the effect of the camera. Many people who cannot use the camera often say that the effect of this manufacturer is poor after installing it. In fact, it is not right. The more reason is that they use it improperly. There are dark and bright rooms, in which dark and bright rooms need to be distinguished from color temperature. For users, just keep the room bright, and never need to install a camera in the dark, because even the best video conference camera will not be better.
It is not recommended to use the video conference camera outdoors, because it is not waterproof, and wind and sun will also reduce the service life of the camera. If it must be used, it is recommended that the camera lens not face strong light. As for waterproof, you can make a shelter, or buy a waterproof camera conference camera, so it is the preferred principle for users to choose the environment - indoor, bright environment.
2. Have a clear desired effect
The video conference camera only occupies the front end of the entire video conference system, which is equivalent to the role of the eyes. As for the images collected by the eyes, the overall effect of the entire video conference system is the result of the transmission of network bandwidth, terminal compression and decoding, so the effect does not only depend on the video conference camera.
If you want to see the direct effect of the camera, just connect the camera to the large screen TV to see it. Before you access the image, you must remove the effect attached to the TV (because the TV has the function of optimizing the image) so that you can accurately see the effect of the camera. The specific operation method is to set the TV to the standard state and turn off the exposure and noise reduction, Then connect the camera, and you can see how the original effect of the camera is. As long as the output image of the camera is very clear (you can see the details of each part of the person clearly), a slight noise is acceptable (if there is no noise, it is false, reducing the clarity to no noise), The operation of the PTZ is very stable and quiet (many people like to rotate quickly, but it is useless because the image display is best seen in the static or relatively static state), and the focus is stable. No matter how close or far the focus is, it is always clear and unambiguous.
3. Select the video conference camera produced by a real powerful manufacturer
Is this camera produced by a competent manufacturer? I don"t even know which manufacturers are there? I believe that most people will have such questions. In the early days, I also had such questions. Even if I asked the construction team that constructed for me, I couldn't tell why. Because the construction team also represents the interests of the party that he cooperates with, it certainly won't choose other brands. That causes many people to choose foreign brands and imported cameras. The effect is acceptable (mainly because they have not compared with other brands), but the exorbitant price and money are earned by foreign people. On the contrary, there are not many people using domestic cheap good products in China. Instead, foreign countries purchase domestic manufacturers' cameras in large quantities. This is a naked satire on our consumers.
The above are the three methods introduced by Xiao Bian to judge the quality of conference cameras. Now many camera manufacturers say they are manufacturers. Is there any way to judge? Next, Xiao Bian will show you how to identify the camera manufacturers
