6.The device can support single picture, picture-in-picture, Three-Picture and four-picture display modes of each channel.
7.H.264, High Profile and H265 video coding standards are adopted for equipment video coding.
8.The device has built-in dual optical drives, which record audio and video information on the scene of interrogation in real-time synchronization and directly on CD-ROM. It also automatically formats and checks the validity of the disc before recording, automatically pops up the disc that does not meet the recording requirements, and automatically closes the disc after recording.
9.Built-in 500G hard disk, real-time synchronous backup of audio and video information on interrogation site, ensure data security storage, support SD card insertion, and support real-time synchronous recording of external mobile hard disk.
10.Hard disks are designed in a disassembly-free way, so they can be disassembled without opening the body. Convenient replacement of hard disk, ensure safe storage of hard disk data.
11.The device adopts dual optical drive, supports direct lithography support, supports 4.7G single-layer, single-sided double-layer 8.5G real-time recording. Use standard 4.7G capacity DVD disc, recording time 1 hour to 24 hours optional.
12.The device supports hash value calculation. When the CD-ROM stops recording, it generates the unique hash value of the video file and writes it to the CD-ROM. It ensures that the contents of the two CD-ROM video files are identical and can be quickly discharged. The recorded CD-ROM data can not be modified or deleted.
13.The device has built-in high-definition evidence acquisition module, which can support 1280*1024, 1920*1080 high-resolution video evidence acquisition, not less than 25 frames/second.
14.The device supports 1920*1080 composite screen, not less than 25 frames/second high resolution direct lithography.
15.Equipment support web page to monitor the working status of equipment, and control recording.
16.The device can set a timing video or a first CD-ROM recording time. The second CD-ROM automatically starts the recording when the first CD-ROM is close to the disk closure.
17.The device supports audio signal to be simulated into dynamic visual graphics, which can be displayed in the video screen synchronously, and can instantly understand the status of audio information acquisition.
18.The device can flexibly adjust the background, color, location and display residence time of the display content.
19.The device has built-in Font library, five strokes, strokes, Pinyin and other input methods. It is convenient to input the information of case number, case name, case handler, case location and person involved in the case, which can be superimposed on the video screen. The display time can be set by itself.
20.The device supports a dual recording system, which can be made either by IE browser or directly by itself without a third-party computer.
21.The device can play CD-ROM video directly on the machine, providing pause, fast-forward and other functions.
22.The video recorded by the device is in the general format of *. TS, which can be played by a general player to facilitate the use of court testimony. Audio-video single file recording and storage ensures the continuity of CD-ROM files, general video format file recording, can be played by QQ video, storm video MEDIA PLAYER and other players.
23.The video recorded by the device can also be set to support encrypted video format. The recorded file can be played only after entering a password.
24.There is no need to install a professional player to play directly in the CD-ROM. The special player can query the key marks during interrogation, click on the marks, and the player can quickly locate the key marks in the video. It can still play the CD without any player on the computer, and quickly locate the focus, saving time in finding the focus.
25.In the process of direct engraving, interrogation transcripts and customized documents (such as evidence pictures and videos) can be simultaneously recorded on CD-ROM to ensure the integrity of case evidence and transcripts.
26.Video recording and video in hard disk can be directed simultaneously by two CD-ROMs, and two CD-ROMs can be repaired immediately instead of one CD-ROM. The time of repairing CD-ROM can be reduced to 12 of single CD-ROM drive, so as to improve the efficiency of repairing CD-ROM.
27.Single video files that can be recorded on hard disk can be cut selectively, and mute shielding can be cut in necessary parts. Video content without formal interrogation is meaningless and occupies the capacity of CD. Useful video can be carved into CD by cutting equipment.
28.Hard disk video has a key marker index. When the device plays, it can choose the key marker. The device will automatically locate the key marker time in the interrogation for playing.
29.Support network transmission support international standard RTSP, RTMP protocol, convenient and compatible with various monitoring systems, the use of city-wide, province-wide networking. Provide RTSP protocol connection address, through VLC (downloadable online) software connection detection.
30.With H.323 protocol, the video conference terminal can communicate directly with the video conference terminal. With the remote auditing function, two-way audio and video transmission can be achieved between the two devices. There is no need for conference equipment to realize remote auditing between the two devices. It supports remote bidirectional audio and video calls and realizes remote auditing.
31.WPS transcription software is built in the device, which can record, support custom template and fast question and answer. It can be uploaded to CD-ROM with one button to record. It supports fast printing. It is based on common programs such as word, WPS and so on. It conforms to the operation habits.
32.Recording software can add ID card information into the recording template by connecting the ID card scanning instrument.
33.The device can be connected to a high-beat device for file scanning.
34.The device can provide WEB service. Users can watch the scene of interrogation (interrogation) remotely and synchronously through browser, and can talk with front-end interrogation (interrogation) personnel through one-way voice. At the same time, the built-in transcription module provides WORD transcription operation and uploads it to CD-ROM.
35.The device has built-in high sensitivity temperature and humidity detection module, which reads the information of environmental detection equipment in the interrogation room in real time and superimposes it on the video screen.
36.The equipment can prevent the loss of interrogation simultaneous recording data due to external influence in the use process. After unexpected power failure and restart, no need to replace the CD-ROM, the original CD-ROM can be restored by non-hard disk guide, so as to ensure the reliability of CD-ROM data.
37.The device has built-in 88-key standard notebook keyboard and mouse touch panel, which supports external mouse input. The device has at least 4 USB interfaces.
38.The device has at least 2 channels of 100Mbps/1000Mbps adaptive network ports to support network expansion and application.
