Multi-camera recording with outdoor cameras
Here are some key points about outdoor multi-camera recording: ** 1. Equipment preparation ** 1. ** Choose the right camera ** - If you were pursuing lightweight personal shooting and wanted a creative high-quality panoramic view, the Shadow Stone Insta360X4 was a good choice. It had 8K30 frame panoramic image quality, small size, and a variety of practical functions, such as selfie stick stealth algorithm, follow-up mode, natural wide-angle FOV mode, disassembled protective mirror, 10 meters waterproof, 130 minutes of battery life, gesture control function, etc. After shooting, you can use Insta360's APP for post-production. - The PXW-Z280V was a professional camera with excellent performance, flexible operation, and strong environmental adaptability. It had the advantages of advanced technology, durability, high industry recognition, good market use, good cooperation, and strong service ability. It was suitable for outdoor shooting such as news and livelihood programs. 2. ** Check device settings ** - All cameras, except for special positions, should have the same parameters. If they are rented equipment or previously used for other projects, they can be restored to the factory settings first. Special cameras can set different frame rates according to needs. For example, shooting high-speed shows can use 120fps frame rate to shoot slow-motion scenes. However, it is not advisable to set too many different frame rates when multi-camera simultaneous editing, so as to avoid synchronization difficulties. - Check the audio settings. You can't just pay attention to the audio, but also pay attention to the current sound, low-frequency noise, and microphone spray. At least bring a directional microphone, because the sound quality of the microphone often can't meet the needs, and adjust the audio settings according to the shooting scene (such as the studio or the park). - Check the storage space. Prepare one or two more memory cards and try not to use the card slot as much as possible because there may be problems with its quality and speed, especially for 4K shooting projects. - Check the cable of the camera. If you can use the SDI, use the SDI. If you can only use the HDMI, use the strong glue to fix the port to ensure that the cable is firmly connected. ** 2. Equipment connection and signal transmission (Take OBG as an example, it can be adjusted according to the actual broadcasting software)** 1. ** Different types of signal access ** - If you have equipment that supports the NDI-protocol (such as some cameras or computers), you can connect its signal to the broadcasting system through the relevant settings. For example, when creating a new scene in OTS and adding a source to find an NDI-based source (for example, adding an NDI-based signal to the teacher's teaching table: Start OTS → Create a new scene → Add a source in the scene → Find the NDI-based source of the mobile phone → Confirm → adjust the position in the scene). - For devices that use the SART protocol to transmit video (such as mobile phones with specific apps), the corresponding connection settings must be made. For example, start the relevant APP (such as the Larix Broadcaster app) on the mobile phone to set it up, create a new scene in the OBS on the PC, and create a new media source. Enter the address corresponding to the SART protocol (such as: slt://<anno data-annotation-id ="43333334 - 4444 - 4414 - 44448 - 888111112200a"></anno></anno></anno>192.168.0.100:9001? mode = caller, note that the IP address is the phone's IP). - For surveillance cameras and other devices that use the RSP protocol, create a new scene in the OTS, add the "VLV" video source in the "Source", and add the corresponding path/Url in the play list (such as rtsp://admin: admin [email protected]: 554/h264/ch1/main/av-stream, etc.). ** 3. Other precautions ** 1. ** Voice Transmission ** - If there are teachers or hosts, they can use devices such as "Little Bee" to make wireless Bluetooth connection with recording equipment such as mobile phones. Students or the surrounding environment can use the built-in microphone of the surveillance camera (you need to log in to the background of the camera to do noise canceling). 2. ** Plane layout and selection ** - Arrange the camera position according to the shooting scene and needs, such as taking a panoramic view, close-up, different angles, etc. If the surveillance cameras did not meet the requirements, he could add more phone cameras. Traditional cameras can be equipped with an ADC (push box) according to the output interface (Bluetooth, PDI), and many of the coders support the protocol of RMP, RSP, SART, and NDI. They also have wifi or 4G/5G networks (note that the NDI-protocol may require additional license fees). If the funds allowed, they could choose to use a special camera for the meeting. Many cameras supported the above agreement. 3. ** Wi-Fi ** - The wireless network should use enterprise products as much as possible, support multi-user dense access (such as tablet teaching scenarios), and support 2.4G/5G signals to ensure stable connection and data transmission between various cameras. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Why is there only one camera with two cameras?
There was more than one camera working. One of the dual cameras was the main camera and the other was the secondary camera. The main camera was responsible for framing, and the secondary camera was involved in imaging. Therefore, after pressing the secondary camera of the mobile phone, you could still take photos, but blocking the secondary camera would affect the quality of the photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Haikang camera timing function
The Haikang camera's time adjustment function can be realized in the following ways: - ** Hard disk recorder time adjustment **: - If the time of the video recorder changed to 1970, 2010, or 2012, it was usually because the button battery on the main board was out of power. It was necessary to replace it with a battery of the same model, then change it to the correct time on the time setting page of the system settings, and click Save. - If the button battery is replaced, the time will still be changed to 1970, 2010, or 2012. It is recommended to connect the video recorder to the Internet and enable the Nuan time correction. If it is inconvenient to connect to the Internet to correct the time or if there are other abnormalities, you can contact the after-sales manufacturer to handle it. - ** Clock of camera equipment **: - Some of Hikvision's network cameras, such as the SS-2CDIXX series, the SS-ipc-B1XX series, and the SS-ipc-T1XX series, did not have a built-in clock battery, so they would return to the initial time after power failure (usually 0:00 on January 1st, 1970). After the device was added with a network platform such as the fluorite cloud, it would automatically be connected to the network to adjust the time and become the correct time. - If it was another series of cameras, the power failure and restart time would be restored to 1970. The equipment could be added to the video recorder or the fluorite cloud, and the network could be connected to enable the time correction using the Nangong protocol or the local computer clock. - In addition to the Haikang 4200 client, the Fluorites computer client under the brand of Haikang could also be used to time Haikang and Fluorites series of network equipment. The steps of the Fluorites studio (computer client) are as follows: 1. He connected the camera to the same local area network as the computer, and changed the IP address of the camera to the same network as the local IP address of the computer. 2. He opened the Fluor Studio and refreshed the search in the "local equipment" on the left. He found the equipment that needed to be manually timed. 3. Right-click the device that you want to manually adjust the time and select "Time". <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Introduction to the camera function in the smartwatch
The camera function of the smartwatch meant that the watch could take photos or videos through the built-in camera. Different brands of smartwatches had different camera functions, but they could basically be controlled through the watch screen or mobile app. The camera was usually located on the side or top of the watch. Some watches also supported rotating the camera to take selfies. The resolution was between 1 million and 5 million. The higher the resolution, the higher the resolution. The smartwatch camera had the following advantages: the shooting effect could meet daily needs. However, there were also some shortcomings, such as limited storage space and inability to store a large number of photos; the shooting angle was limited by the position of the camera; the camera was small and had high requirements for light, so it was necessary to choose a well-lit environment when shooting. In addition, some smartwatches could be used as a real-time viewfinder and remote shutter for mobile phones. For example, after the Apple Watch was connected to the iPhone, it could be used to view the mobile phone's camera image and remotely shoot by raising the wrist on the watch screen. There were also smartwatches that could take photos remotely via Bluetooth connection when taking selfies or group photos, which could solve the problem of shooting when there was no selfie stick or tripod. Children's smartwatches also had camera functions. Some of them also had functions such as beauty, adding friends, and posting on WeChat Moments. In addition to taking photos, some children's smartwatches also had functions such as positioning, face recognition, WeChat Moments, and payment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
