Double Blu-ray Disc Drive Synchronized Interrogation High Definition Real-time Direct Lithography (Compatible with DVD Disc) |
Using the advanced technology of direct lithography of video disc and the physical characteristics of CD itself, the audio and video data in the process of interrogation are directly recorded on CD 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; the latest large-capacity direct lithography of blue light is selected. 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. The Blu-ray disc with different capacity can be automatically identified and the best bit rate can be selected according to the capacity of the disc.24Hourly high-definition recording; for4.7G DVDCD-ROM Support6Hour high definition recording. |

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. Double CD-ROM drive can work normally without hard disk. Hard disk video using external mobile hard disk can not cause any video data residue in the device after recording. It can effectively prevent leaks caused by multiple people sharing an interrogation equipment. |

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. |

|
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. |
|
|
|
