AVST-S600 High Definition Interrogation CD-ROM Direct-engraving Terminal
AVST-S600 refers to GA/T 882-2010 "Digital Interrogation (Interrogation) Recording System Technical Requirements", specially designed for the special needs of public security interrogation, procuratorial interrogation and discipline Commission inquiry. It fully meets and far exceeds the standard requirements of GA/T 882-2010, and adopts military-level standard testing and production, which is rock-solid.
AVST-S600 adopts advanced parallel processing technology of DSP. It is a powerful professional equipment for real-time direct lithography of interrogation video. It carefully adjusts and optimizes the core laser processing module, which can support multi-CD-ROM real-time and long-time direct lithography.
AVST-600 is suitable for synchronous recording and video recording in fixed interrogation rooms and interrogation rooms of public security, procuratorate, discipline commission, customs and security departments. It collects real-time sound, image, environment and other important information on the spot, and records them truthfully and accurately on DVD disc. The case is filed and saved after hearing.
Product characteristics:
webcast
Unique multi-stream technology, H264 compression processing, and with fault physical isolation protection mechanism. At the same time, a high-performance image synthesis module is used to synthesize multiple independent pictures, and H264 High-Profile compression algorithm is used to store and transmit them. Users can access the synthetic and independent video of the interrogation scene through the network, and can enlarge each small picture separately for observation. The network bandwidth occupied is 1/4 of that of the device without synthetic module. It can process 1080P four pictures under 2M bandwidth.
Triple simultaneous backup of CD-ROM, hard disk video and network
Digital interrogation terminal is equipped with DVD CD recorder, built-in hard disk and internal backup, remote network backup and triple data guarantee to ensure the security of interrogation data.
Synchronized Direct Carving of Interrogation Data with Double CD-ROM Drives
Using the advanced video direct lithography technology and the physical characteristics of the CD itself, the interrogation process is directly fixed on the CD-ROM, which meets the actual demand of obtaining the original audio-visual evidence at the scene of the interrogation. The technology of CD-ROM direct lithography can record the field data in high definition for a long time, which fully meets the needs of post-event data access.
CD-ROM Data Recovery
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.
Selection of recording time mode
1-24 hours adjustable, can set recording countdown time reminder, set time arrival, the system sends a reminder signal.
High Definition Synthesis Technology
Provides settings to select synthetic images for SD or HD. 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.
There are the following patterns
1. Single channel display
2. Picture-in-picture provides a small picture position adjustment mechanism. Users can choose the size, location and access channel of the picture.
3. Trisection
4. Quadripartition
5. Remote mode 1
6. Remote mode 2
It can adjust the chroma, brightness, contrast and sharpness of each video picture (including composite picture).
CD Encryption
The encrypted disk is encrypted by cipher combined with optical disk track encryption to ensure the uniqueness of the carved content.
Quick introduction
The data of backup hard disk can be quickly exported to CD.
Multi-disc support
Disk support: DVD+/-R, DVD+/-RW, DVD+/-R DL, DVD-RAM, etc.
Quick access to general environment
For CD-ROM, in other computer environments, the contents of CD-ROM can be replayed without installation.
Audio Display
Using audio information visualization synchronous superposition technology, the voiceprint information of interrogation content is superimposed on the screen of interrogation scene synchronously, which provides a visual technical guarantee for background managers to keep abreast of the audio information status at any time. It not only achieves the confidentiality of interrogation content, but also prevents verbal evidence caused by the failure of audio acquisition equipment. Loss occurs.
Command Interview
Support network command and on-site real-time command. The front-end uses spectrum display technology. The case handlers do not need to wear headphones all the time. When the command signal enters, it produces a jump prompt.
Network on Demand
By login ie, the video data in the hard disk connected by the device can be retrieved and replayed.
Audio and Video Loss Alarm
An alarm signal will be sent when the system loses audio and video.
Digital audio mixing
The advanced digital interrogation audio quality adjustment technology and dual audio input channel ensure the high definition of speech evidence collection and data security.
Video Header and Hard Disk File Text Input
Through the header setting column: input the case number, case name, case handling personnel, case handling location, personnel involved, etc. This information can be entered into Chinese characters by mouse handwriting or keyboard pinyin to fill in the above content, and then save the header setting. Provide a button to trigger the text overlay display of the header. After 10 seconds of display (can be set), automatically hide without overlay.
Synchronized Superposition of Temperature and Humidity Information
Real-time reading of temperature and humidity information (text) of remote devices is superimposed on the video screen.
time synchronization
When the device is on, it synchronizes with the clock server first, and then with the time of the device itself and the environment display screen. If it cannot synchronize with the clock server, the time of the device itself is synchronized with the time of the environment display screen. Background can be device time server information
Data Copy
1. Insert the USB mobile hard disk, copy the video files in the system hard disk to the mobile hard disk.
2. If an external storage device exists and its storage capacity is guaranteed at a certain time (e.g. a large capacity mobile hard disk), the hard disk video can be stored in a mobile hard disk, without any data writing trace on the local hard disk in the device.
Supporting command intercommunication
Support network command and on-site real-time command. The front-end uses spectrum display technology. The case handlers do not need to wear headphones all the time. When the command signal enters, it produces a jump prompt.
