What is the role of the panoramic HD recorder?

Panoramic HD video recorders are used for medium and large conferences, classroom lectures, medical endoscopic laparoscopic surgery, medical training, expert lectures, interactions, court trials, group gatherings, video conferences, and high-definition audio and video surveillance videos for important occasions. The panoramic HD recorder can record multiple camera videos and accompanying audio as a video file, which is of great significance. In order to further clarify the role of the panoramic HD video recorder in practical applications, the author of this article interviewed the technicians of Shenzhen Chunyuan Liying Electronic Technology Co., Ltd., the R&D unit of the panoramic HD video recorder, and edited it into this article.

1. The panoramic HD video recorder is essentially different from the traditional surveillance video recorder.

The traditional high-definition video recorder can only record the audio and video signals input by each channel as independent audio and video files. When several signals are input, it will be recorded as several files. When copying to the mobile hard disk, it is also based on the number of input cameras. Copy, when playing the computer, you can only play audio and video files of one of the cameras. No matter how many cameras are installed at the conference site, only a local scene scene shot by a camera can be seen after copying.

The panoramic HD recorder supports at least recording the video captured by the 4-channel HD camera and the matched audio as a video file, which is displayed on the screen in a multi-picture picture-in-picture manner. When copying to the mobile hard disk while playing on the computer, no special playback software is needed. With the normal video player, you can play the audio and video images of the four-picture combined picture-in-picture. You can watch the four cameras installed at different positions on the conference site at the same time. The live situation of the meeting, real reproduction of the scene of the entire venue.

The traditional video recorder can only retain the partial picture data captured by one camera. The panoramic video recorder retains the panoramic picture data captured by multiple cameras.

In terms of camera ports that support input, traditional multi-channel recorders can only support analog port or network port input recording, such as AV, AHD, NVR interface, while panoramic HD recorder supports input HDMI, DVI, VGA, SDI digital HD port. The input resolution is true 1080P60Hz HD video. After recording, it is digital 1080P30\25hz. It has high definition, smooth playback and no broken frame. It is a real HD recorder.

In terms of audio input, the traditional multi-channel recorder, the less organic type can match the input analog audio for each input camera, most of which can only match the audio for one-half of the input video, and the analog video recorder, regardless of the input How many channels of video can only match one channel of audio. Moreover, there is no way to mix and match flexibly.

The panoramic HD recorder not only supports the video itself to contain audio input video, but when the video port does not contain audio, it can input audio from the configured port. The panoramic HD recorder supports recording 4 channels of HD video as one file, which is more scientific and flexible in audio configuration. You can select four channels of audio to record with video at the same time, or you can select which audio and video to match recording with one button. At the same time, you can mix audio input from the Lotus port.

The four-way picture is recorded as a video file. In the picture-in-picture display mode, the panoramic HD recorder also has a scientific configuration scheme. Specifically, there are four screens of square display, upper and lower three small displays, left and right two screen displays, upper and lower two screen displays, and single screen full screen display five modes, which can flexibly select the display mode according to the needs of the scene and the number of cameras input.

The panoramic HD recorder not only has four-screen panoramic video recording function, but also three input interfaces for independent recording. You can input three SDI, HDMI, VGA interface cameras or playback devices, you can record at the same time or at any time. These three independent input interfaces can be recorded simultaneously or alternatively with the four panoramic video input interfaces of the front end.

The panoramic HD recorder supports two built-in 3TB 3.5-inch hard drives, and the single-channel recording takes up 1.8GB of hard disk space per hour. Both hard drives can be set to loop recording or redundant recording (two hard drives simultaneously record the same video). The audio and picture modes of the panorama function are operated by the joystick button, and the specific recording operation is controlled by the mouse.

The panoramic video recorder supports recording at any time, scheduled recording, and motion detection recording; it supports non-delayed live broadcast; you can watch while watching and recording. Support four screens, seven screens to select live or one-click to zoom in on the live stream; also supports any choice of playback.

The panoramic video recorder has HDMI, VGA, and AV output interfaces, and supports simultaneous LCD TV and computer monitor playback.

The video recorded to the internal hard disk can be copied to the mobile hard disk via USB. When copying, you can select H264 or AVI format.

The panoramic HD recorder has a wealth of networking features. Support remote computer, shouji live, voice intercom; support remote computer playback, download, screenshot, and computer recording. You can perform system settings such as image quality adjustment, recording time reservation, and personnel management on the remote computer, as well as perform machine restarts.

Second, the application of panoramic HD video recorder in practice

(1) Application in local conference video recording and teaching training video

Generally, when a local meeting or lecture video is held in a conference room or classroom, the conventional method is to install a different number of cameras according to the size of the conference room and the number of participants. For example, an HDMI camera is fixed to the main platform, on the left and right sides of the conference hall. Each HDMI camera is installed. In order to cooperate with the main presentation, the rostrum also has a desktop computer that plays courseware. If you want to record the pictures taken by the three cameras and the courseware pictures played by the computer, it is difficult to use the traditional surveillance video recorder. With a panoramic HD DVR, you can do it.

Input the HDMI (DVI) output ports of the three cameras into the input interface of the recorder. The VGA port of the computer is input to the VGA input port of the recorder. The output of the recorder is connected to the LCD TV or computer monitor. After booting up, the four screens entered will be displayed simultaneously on the screen. The layout mode of the four screens can be adjusted through the joystick buttons on the front panel of the recorder. It can be set to a square layout of the same size as four screens, or a layout mode in which the chairman screen is on top and the other three screens are below.

In terms of audio, you can set only the voice of the recording speaker, or set the audio of the recording speaker to discuss the interaction with the participants. You can also set the audio to record only the questions answered by the students, or set the audio of the courseware recorded on the computer. You can additionally enter the dubbing of the host.

After the conference is recorded, not only can the video recorded to the internal hard disk be played by this recorder, but also the audio and video of the four screens will be displayed at the same time. When the mobile hard disk is played on the computer, it is also the audio and video of the four screens. Just keep this file and keep the audio and video data of the conference panorama taken by the four cameras.

(B), the application of recording endoscopic laparoscopic medical surgery

The HDMI output interface of the laparoscopic laparoscopic device is connected to an HDMI input interface of the panoramic video recorder, and the HDMI output interface of the camera of the surgeon and the nurse is connected to another HDMI input interface of the panoramic video recorder, which can be simultaneously viewed on the television screen. To two screens, you can adjust these two screens to the left and right display modes. As long as the surgeon wears a microphone microphone and the recorder is connected to the audio receiver, you can explain it while doing surgery. Then the video after recording is also Two pictures, and you can hear the audio from the surgeon.

If the video recorder is connected to the network, the remote doctor or patient's family can also watch the whole process of the operation through the mobile phone or computer.

(III) High-definition monitoring application for square gathering sites, large-scale construction sites, large reservoirs, etc.

Four high-definition cameras are installed according to the shooting angle at different positions in the scene, and the four input interfaces of the panoramic video recorder are directly input or converted by the relay extension, and the live host or observer inputs the audio to the video recorder through the microphone, and after starting the recording, copying The picture that is played on the computer by the mobile hard disk is the overall picture taken at four different angles, and the sound of the scene and the voice of the commentator are also recorded in synchronization with the video.

(4) Application in video recording of small conference rooms

In a small conference room or classroom, you only need to install a high-definition camera. When recording with a panoramic HD recorder, after inputting the video signal, adjust the display mode to single-screen full-screen mode. The speaker's microphone audio access and audio input interface corresponding to the video input, if there is other people's microphone audio, then enter any other audio input interface, after starting the recording, the audio and video synchronization video can be normally performed.

(5) Application in video conference video recording

When using a conference terminal device for remote video conference, the participating parties connect their respective conference terminal devices through the network, and the HDMI output interfaces of the respective conference terminal devices are connected to the television, and the screen will be multi-picture in the picture-in-picture. The mode sees the window of all participants in the distance and the audio of the distant speech.

The video conferencing terminal device is characterized in that the audio that is spoken locally to the conference-dedicated omnidirectional microphone can be transmitted to the remote party, and the audio of the remote participant who is transmitted from a distant place can also be heard on the local television, but the local speaking Audio cannot be transmitted to the local TV via HDM. This audio feature puts new demands on the video conferencing recorder. If you use a normal HDMI input recorder to record, you cannot record the local speaking audio.

The panoramic HD recorder has the practical mixing function to meet the requirements of recording video conferences.

It is ideal to record the remote local audio and video. In addition to configuring the omnidirectional microphone necessary for the conference terminal, a local microphone microphone and mixer system should be configured.

Connect the HDMI (DVI or VGA) output interface of the conference terminal device to the HDMI (DVI or VGA) input interface of the panoramic recorder, and connect the lotus audio output interface of the local mixer to the first white lotus audio input interface of the panoramic recorder. Connect the recorder to the TV or monitor. After booting up, adjust the display mode to single-screen full-screen mode. After the conference starts, start the recording system. After the video is completed, not only the video played by the recorder to the TV is the remote local audio and video, but also the audio and video files after being played to the computer. It is also the live audio and video data of all parties involved.

(6) Application in court trials

The court installed 3 HDMI (DVI) output cameras, a VGA output camera, an alignment judging panel, an alignment defendant and the plaintiff seat, an alignment defense lawyer, and an alignment jury. The HDMI (DVI, VGA) interface of the four cameras is connected to the four-in-one input interface of the panoramic video recorder; the audio input of the microphone microphone and the mixing console in different positions and the audio input interface corresponding to the camera. In addition, a spare Lotus audio interface is input to the first white lotus audio port of the panoramic video recorder. After starting the recording, adjust the video display and audio mode as needed. After the video is completed, an overall four-picture picture-in-picture audio and video file will be produced, which will fully display the panoramic scene of the trial venue.

(7) Application of multi-input interface when each input screen needs to form a separate recording file

In some occasions, not only do you need multi-screen video, but also want to make some of the cameras form a separate video file, the panoramic HD recorder can play a perfect function.

For example, there are three high-definition cameras with HDMI output interfaces, which can be connected to a HDMI one-two splitter before being input to the panoramic video recorder. The two HDMI signals respectively are connected to the four-in-one input interface and separate HDMI. Input interface, so that after the video is started, not only the pictures taken by the three cameras are recorded as a three-in-one video file, but also separate video files are recorded. It can be played by this unit or copied to the computer for playback.

If you do not need three-in-one video, you don't need to use the split screen. Just input the HDMI signal of the camera to the HDMI input interface of the independent recording.

This article simply enumerates the use scenarios of some panoramic HD recorders. With more different usages, guests can flexibly master and use them scientifically. The appearance of the panoramic HD recorder solves the shortcomings of the traditional video recorder that can not save the conference live. Whether it is 2 or 3 or 4 cameras installed on site, it can be recorded as a video file, which can perfectly reproduce the audio and video in different corners of the conference. The live is a real live panorama cloning tool. The audio solution of the panoramic recorder eliminates the single option of the traditional recorder or the mode of missing audio recording, which can meet the needs of various conference audio and video recording.
