What about the camera audio?

How to turn on the sound when the camera is connected to the computer?

From the toolbar in the lower right corner of the desktop, find the sound icon (small speaker), right-click to enter the sound adjustment dialog box, and check whether the microphone is selected or turned on from the properties or advanced settings. Generally speaking, by default, the microphone is unselected or muted, or the volume is very low. Select it, unmute it, and turn the volume to the highest level.

If you can't find the speaker icon in the lower right corner, start from the lower left corner-Settings-Control Panel-Sound, voice and audio devices.

If you confirm that the computer is set correctly, just look at the manual of the camera and follow the steps in the manual. Some camera images and sounds need to be adjusted from the camera's own program. The image of the camera I used before must be opened from the program that comes with the camera. After installation, the camera is off by default.

Video conference camera and solutions to common audio problems

With the increasing use of video conferencing, the requirements for video conferencing are getting higher and higher. For video conferencing, everyone will say that video is more important, but it is not. In video conference, audio is the most important, because the communication between participants is mainly realized through audio dialogue or discussion. So, here are the solutions to the common problems of video conference cameras and audio. Welcome to read and browse.

First, the solution of the video conference camera problem

(1) After the conference camera is powered on, there is no action and no image.

This kind of problem is generally caused by power failure, switching power failure and loose plug of power cord, which is relatively simple. Users can solve the problem by troubleshooting the power supply and plugging in the power cord plug.

(two) the conference camera in the application process of self-inspection can not be carried out or accompanied by noise.

For such problems, users can first check whether the power cord is loose, because the loose power cord is easy to cause insufficient power supply, which directly leads to the problem. If the power cord is not loose, it is probably a mechanical failure, and the user needs to send the product for repair.

(3) In practical application, the conference camera is not controlled by the remote controller.

Generally speaking, this problem is mainly caused by insufficient battery power or the long use distance of the remote controller. Users can solve it by replacing the remote controller battery and adjusting the use distance.

(4) When the conference camera rotates, the camera image is lost.

Generally speaking, this problem is mainly caused by insufficient power supply or poor video line contact of the camera. Users can solve this problem by checking whether the power cord plug is loose and replacing the video cable.

Second, the solution to the audio problem of video conference

With the increasing use of video conferencing, the requirements for video conferencing are getting higher and higher. For video conferencing, everyone will say that video is more important, but it is not. In video conference, audio is the most important, because the communication between participants is mainly realized through audio dialogue or discussion.

(a) The voice is very low during the audio call.

This is mainly manifested in the fact that the voice made by the other party is very light, and it takes a lot of effort to hear what the other party is saying. The general problem lies in sound collection. We can test our speakers or speakers first, and then play them on the local computer to see if the volume is loud enough. If it is determined that the audio downlink is normal, it can basically be judged that the problem lies in the remote uplink, and generally the input volume of the device can be adjusted.

(2) Audio calls are noisy.

The magnitude of noise has two main effects. First, there may be noise sources such as fans and air conditioners during the meeting, while general meeting pickup products will not have special noise treatment, which will lead to noise being picked up. Second, the audio uplink volume is too large, which will lead to a slight movement with a large sound collection and noise. Of course, sometimes there are some functions in terminal management, such as noise reduction and mute, when these functions are turned on.

(3) You can hear your own voice in the video conference.

During the video conference, I found that I could hear my own voice coming back. For example, it is easy to happen when many mobile phones are hands-free. In terminal management, you can check the echo cancellation function to reduce the echo. If the conditions are limited, we can reduce the sensitivity of audio input devices, increase the spatial distance between pickup devices, speakers and power amplifiers, and reduce the sound and improve the echo through the distance effect.

1, resolution

Resolution is the ability of a camera to analyze and distinguish images. It has a direct impact on the image effect. Generally speaking, the resolution can be divided into photographic resolution and video resolution, that is, the resolution when shooting still images and the resolution when shooting moving images. In the practical application of video conference, the photo resolution is generally higher than the video resolution. The video conference cameras on the market can give different types of resolutions, so it should be noted that some resolution marks refer to the interpolation resolution that these products can achieve by using software, but there is still a certain gap compared with the hardware resolution.

2. Pixels

Pixel value is an important index that affects the quality of video conference camera, and it is also an important symbol to judge its advantages and disadvantages. The pixel value of early products is generally around 654.38+ 10,000. Because of its low technical content, it is on the verge of elimination, so users should pay attention to it when purchasing. But you don't have to blindly consider the pixel value. Because the higher the pixel value, the stronger the product's ability to analyze images and the higher the ability to process data on the computer. If the computer configuration is not high enough, it will delay the picture and affect the transmission of video conference. Therefore, users should consider their own equipment comprehensively when purchasing products, and don't blindly pursue the trend.

Step 3: lens

Lens is an important part of video conference camera. At present, the photosensitive elements of video conference cameras on the market can be divided into CCD and CMOS. The advantages of CMOS are low manufacturing cost and much lower power consumption than CCD. However, due to the immature application technology, it has not been widely used, but most people in the industry think it is the future trend. At present, the dimensions of CCD elements are mostly 1/3 inches or 1/4 inches. Under the same resolution, it is better to choose a larger element size. Because there is a big gap between the video streaming effect of analog camera and CCD camera, users should not choose analog camera cheaply when purchasing, so as to avoid the loss of unnecessary shopping.

Step 4 connect

Without USB interface, high data transmission capability is impossible. However, there will be a lot of data transmission in the actual use of video conference cameras, so users should pay attention to it when purchasing. The high speed of USB data transmission determines the application of video conference camera. The high-speed transmission of USB data breaks the bottleneck of mass data transmission of image files, which makes the computer receive data faster and the playing effect of dynamic images smoother, which is very important to the meeting effect. In addition, USB products have been widely accepted by computer users because of their plug-and-play and easy use. The video conference camera adopts USB interface, which can make its hardware detection and installation more convenient.

5. Transmission bandwidth

At present, high definition is the mainstream trend of video conference promotion. However, it should be noted that to achieve the effect of high definition, the whole high-definition equipment needs to cooperate. It is not enough to configure high-definition cameras and high-definition live-action terminals, and network bandwidth is also one of the important factors. Therefore, users should fully consider their own bandwidth capacity when purchasing HD. If the bandwidth is not enough to support high-definition communication, packet loss will occur, which will affect the conference effect. Standard definition or high definition should be used according to the facts, and must not blindly follow the trend.

What should I do if there is noise in the audio recorded by the camera?

If the mixer is a live speaker, the sound standard is different from that of the camera. The input camera will definitely have noise (power amplifier). So it is best not to use this method. Actually, it's better to put a microphone next to the speaker.

If it has been recorded, you can only use "audio software" to reduce the noise.
