Parameters of fixed HD interrogation synchronous direct engraving equipment | |||
| Name of device | Serial number | parameter list | |
| | 1 | Double CD-ROM Synchronized Interrogation High Definition Real-time Direct Lithography | Using the advanced technology of video direct lithography and the physical characteristics of CD itself, the audio and video data in the process of interrogation are directly recorded on CD-ROM without any third-party storage medium, which meets the actual demand of real-time direct lithography at the scene of interrogation to obtain the original audio-visual evidence; selecting the latest high-capacity CD-ROM direct lithography The technology can record the field data for a long time and with high definition, which fully meets the need of post-event data access. It can automatically identify the discs with different capacity and select the best bit rate according to the capacity of the disc.4.7G DVDCD-ROM Support6Hour high definition recording. |
|
| 2 | Be divorced fromPCplatform | Adopt disengagementPCThe platform's embedded interrogation (interrogation) parallel encrypted direct writing of double CD-ROM drive data and independent backup technology of hard disk data parallel synchronization are simple to operate and stable to operate. Dual CD-ROM drive can work without hard disk. When necessary, it can not cause any video data residue in the device after recording. It can effectively prevent the leak caused by multiple people sharing an interrogation device. |
|
| 3 | Automatic recovery of CD-ROM data | Advanced CD-ROM real-time recording data automatic protection, to prevent the use of the process due to external influence, resulting in the loss of interrogation synchronous recording data. When the accidental power failure occurs during the recording process, the original CD data can be automatically recovered after power-on. |
|
| 4 | Key Markers | In the recording process, the key content can be marked by video dotting, and the dotting position will be displayed on the progress bar when playback, which can be positioned directly to the dotting position. |

|
| 6 | Hassy Value Encryption | When the recording is completed, the system automatically calculates the hash value of the video file and records it on the CD to ensure the authenticity and validity of the video file. |
|
| 7 | Telemessaging function | The point-to-point communication between the two hosts can be realized to realize the function of remote messaging. |
|
| 8 | Digital HD Video Input | Supports 4-channel HD-SDI 1080P video input and multi-channel picture overlay. |
|
| 9 | Recording time | Single disc recording time1－24The hours are adjustable. |
|
| 10 | High Definition Picture Composition Technology | High Definition Video Composite Picture Resolution1920*1080。 The multi-screen digital synthesis technology is used to ensure the simultaneous shooting of close-up pictures of suspects at the scene of interrogation and panoramic related scenes in the interrogation room. The pictures are displayed and fixed in a picture-in-picture manner to meet the corresponding relationship of fixed chains in the interrogation scene pictures. |
|
| 11 | display mode | 1The channels are simple.2Painting in Painting;3Three-part segmentation;4It can adjust the chroma, brightness, contrast and sharpness of each video picture (including composite picture), and can select and adjust the size, location and access channel of any picture. |
|
| 12 | CD-ROM Detection | It provides the basic data detection function of optical disc. The system automatically detects the placed optical disc, identifies the type of optical disc, the serial number of optical disc, whether it is a blank optical disc and other information. |
|
| 13 | Automatic formatting of CD-ROM | The blank disc can be automatically identified and formatted. |
|
| 14 | Automatic Sealing | After reaching the predetermined recording time or stopping the recording manually, the system will automatically seal the data CD, so that the remaining space of the data CD can not continue to write data. |
|
| 15 | Quick introduction | The data of backup hard disk can be quickly exported to CD. |
|
| 17 | Quick access to general environment | For data access CD-ROM, in other computer environments, the content of CD-ROM can be replayed by general player without installing special player. |
|
| 18 | Audio Display | Using audio information visualization synchronous superposition technology, voiceprint information of interrogation content is superimposed synchronously on the screen of interrogation scene.,It provides visual technical guarantee for background managers to keep abreast of audio information status at any time. It not only ensures the confidentiality of interrogation content, but also prevents the loss of verbal evidence caused by the failure of audio acquisition equipment. |
|
| 19 | Command Interview | Supporting network remote command, any authorized user can login remotely through user name passwordIEAccess equipment, remote command of interrogators. |
|
| 20 | Network Live Broadcasting and On Demand | Log inIEIt can watch the real-time video of the interrogation scene, and retrieve, playback and download the video data in the hard disk connected by the equipment. |
|
| 21 | Audio and Video Loss Alarm | An alarm signal will be sent when the system loses audio and video. |

|
| 23 | Digital audio mixing | The advanced digital interrogation audio quality adjustment technology and multi-audio input channel ensure the high definition of speech evidence collection and data security. |
|
| 24 | Video Header Text Overlay | With the embedded text pre-processing technology of video superposition, the contents of CD-ROM headers such as case number, case name, case handler, case location and person involved can be superimposed on the video screen at any time, and the time of superposition can be set. |
|
| 25 | Real-time superposition of temperature and humidity information | Real-time reading of environmental information display screen information in the interrogation room, superimposed to the video screen. |
|
| 26 | Real-time overlay of time and date | The time and date of the interrogation host are synchronized with the clock server, the environment display screen is synchronized with the interrogation host, and the information of the time server can be set in the background; the time and date are superimposed on the video screen in real time. |
|
| 27 | MACAddress binding | provideMACAddress list input, can be set to only hereMACOnly computers in the address list can be accessed.MACThe maximum number of addresses stored is255One. No startup settings MACWhen the address is bound, the authorized user can log in and access any computer in the network. |
