Video cameraIn photography, there was no such thing as a "camera". If one were to take it literally, it might be a camera that was held by one's hand during the filming process. There were many types of cameras, such as DSLR cameras, which were favored by professional photographers with high image quality and a wide range of lens options; Mirrorless cameras were light and high-performance, which were loved by photography enthusiasts; Film cameras had a unique texture and shooting experience; and smartphone cameras were convenient and instant, which were the main tools for public photography. When operating these cameras, it involved hand-held operations, such as controlling the exposure of the camera (the amount of light entering the camera was determined by the aperture, shutter speed, and Iso-sensitivity), choosing the appropriate lens (such as a wide-angle lens for scenery, a telephoto lens for distant objects), and using composition techniques (such as the rule of thirds, symmetrical composition, guide lines, etc.) to shoot the ideal work.

How to connect the video conference camera to the video on the phone camera?If you wanted to connect the phone camera to the video conference, you could do it with some software. For example, to use the VR virtual camera software, the steps are as follows:
1. He downloaded the "DV Virtual Cameras" on his phone and computer, and connected them to the same Wi-Fi.
2. When the phone and computer turned on the "VR virtual camera" at the same time, the software would automatically search for the device.
3. After clicking on the name of the computer device on the mobile phone, the screen of the mobile phone camera would appear on the computer screen, and then the computer software would be minimized.
4. Turn on the PC Tencent Meeting conference. Before or after joining the conference, select "Video" in the "Setting" of Tencent Meeting, select "DV virtual camera" in the "Choose a device", and return to the conference. Be careful to turn on the video function of Tencent Meeting. Otherwise, you won't be able to see the screen of the phone even if you successfully add the camera. For better presentation, the screen of the phone should be horizontal as much as possible. The portrait screen will flip.
Another method was to use the EasyBot software:
1. For USB cameras to connect to Yibo, some cameras needed to be manually installed with drivers. You needed to check in advance whether the model of the camera was a driver-free camera. If it was not a driver-free camera, you had to download the latest version of the driver from the official website of the camera brand. In the drop-down menu of Yibo channel, you could choose the USB camera. If it was not recognized, you could first turn off the firewall and anti-virus software to restart Yibo.
2. To download the iPad app on your phone (Android phones can search for iPad wireless cameras in the major app stores; Apple users can search for iPad wireless cameras in the Apple app store and download them).
3. After downloading the app, he opened the Yibo mobile app and saw a gear in the lower right corner. He clicked on the gear to enter the settings of the mobile app. He first selected the transmission method to Yibo Cloud and received a 6-digit connection code. He adjusted the video format and bit stream (the video format should be the same as the video format on the computer, such as 1920*1080).

The difference between a video camera and a cameraThere were many differences between cameras and video cameras:
* * 1. In terms of shooting time **
1. * * Cameras **
- Cameras had an obvious advantage in terms of shooting time. It could continuously shoot videos for a long time, suitable for scenes that required long-term continuous recording, such as meetings, business events, performances, etc., which lasted more than three hours. It could even be used for live broadcasts.
- Its body was larger, mainly for heat dissipation. When shooting a video, the machine components such as the mos sensor, memory card, etc. generated a lot of heat. Cameras could be used in a variety of ways to ensure long-term shooting. For example, many of them were designed with three pieces of light sensing elements, which collected one of the three primary colors to reduce the working consumption of each piece of light sensing element. They could record for a long time without stopping or reducing the quality of the light sensing element due to heat dissipation problems.
- The batteries of the cameras were usually large and easy to disassemble and replace. Some of them also supported direct plug-in work, which could achieve unlimited battery life. This was very suitable for studio recording and broadcasting work with fixed cameras. Some of the newer cameras, even if they were designed with a large sensor, would also be equipped with a cooling fan (such as a camera used for filming) to ensure stability during filming.
2. * * Cameras **
- The camera was mainly designed to take photos and had a disadvantage in long-term video shooting. Ordinary cameras did not have a huge heat dissipation problem because their main task was not to shoot videos for a long time. Therefore, if they were used to shoot videos for a long time, there might be problems due to poor heat dissipation, such as interruption of shooting and deterioration of image quality. Moreover, the battery life of the camera was limited, so it was not suitable for long-term continuous video shooting.
* * 2. In terms of reliability **
1. * * Storage Security **
- * * Cameras **: Cameras are mostly designed with dual memory cards, or they can be easily connected to external hard disks and video recorder. Due to the high storage capacity requirements of the video, in order to ensure that the captured content could be stored safely and securely, and to avoid problems such as pause, crash, and material loss due to insufficient storage space or insufficient storage speed, the camera was specially optimized in terms of storage security.
- * * Cameras **: Cameras are mainly designed for photo storage, and their video storage security is not as good as that of video cameras. In particular, they may face more risks when dealing with large-capacity video storage, such as the storage speed may not be able to meet the continuous writing requirements of high-bit-rate videos.
2. * * Transmission Security **
- * * Cameras **: Cameras have a variety of transmission devices. Not only can they be transmitted through data cables, but they also have specialized multi-terminal transmission connections for video and audio. This connection method is more reliable than ordinary civilian cameras. It is indispensable for live broadcasts and multi-camera access to the director station.
- * * Cameras **: The transmission function of cameras mainly focuses on photo transmission or simple video export. The reliability of video and audio transmission connection is not as good as that of cameras. It may not meet the requirements of some professional video transmission scenarios.
3. * * Protection and Security **
- [** Video camera **: From the appearance design, the video camera has been specially reinforced and protected in many aspects.] For example, the lens was basically equipped with a durable square protective cover, which was more tightly protected than the camera lens cover; anti-drip treatment was done on various parts, which made it more water-resistant than ordinary mobile phones and cameras in special environments; The data interface, audio interface, and other parts were protected by rubber, and the design of the non-changeable lens also made the phenomenon of dust almost non-existent.
- * * Cameras **: Although some cameras have the "three-defense" feature, the overall protection is not as good as the protective design of the camera specifically for the video shooting environment. It may be more easily damaged in some harsh shooting environments.
* * 3. In terms of audio recording effects **
1. * * Cameras **: Cameras have better audio recording effects. This was an important advantage that made it suitable for video shooting. It could provide high-quality audio recording for videos.
2. * * Cameras **: Cameras are usually not as good as video cameras in terms of audio recording. They may not be able to meet the needs of video recording that requires higher audio quality.
