Remote arraignment system solution

Applicable units of the plan
Public security bureaus, courts, procuratorates, disciplinary inspection and other units
What difficulties are encountered in the construction of the remote arraignment system?
, poor quality of remote image transmission
, echo interference from remote audio transmission
, difficult to save data, inconvenient data retrieval
, weak two-way interactive control function
Solution
1. Remote interrogation room structure
The high-definition synchronized audio and video recording host will synchronously burn the audio and video information to the CD, and synchronously back up the audio and video information to the hard disk.
A close-up camera clearly captures a close-up of the front of the investigators.
The observation camera can be adjusted to take pictures of the personnel handling the case as needed
The gooseneck microphone clearly collects the voices of the personnel handling the case on site.
, LCD displays evidence or plays video to suspects.
, case-handling computer calls case-handling related materials, electronic evidence presentation, video CD playback, transcript entry
, printer prints transcripts, evidence and other documents.
The digital audio processor eliminates echo interference in two-way audio transmission.
, The power amplifier amplifies the sound of the remote audio
, The speaker outputs the amplified sound
2. Structure of the detention center interrogation room
, The high-definition synchronous audio and video host synchronously burns the audio and video information to CD, and synchronized backup to the hard disk
. The close-up camera clearly captures the frontal close-up of the suspect.
. The panoramic camera clearly captures the surrounding environment of the suspect
. The observation camera is controllable and the observation screen can be adjusted as needed
. The pickup clearly collects the voices of the suspect and staff at the scene.
. The environmental display screen displays the scene time, date, temperature and humidity
. The LCD display shows evidence to the suspect or plays the video.
, control panel + alarm light. The outdoor alarm light is connected to the indoor control panel, integrating interrogation status prompts, linkage alarms, and remote command interaction to effectively standardize the interrogation order.
, case-handling computer calls case-handling related materials, electronic evidence presentation, video CD playback, transcript entry
, printer prints transcripts, evidence and other documents.
The digital audio processor eliminates echo interference in two-way audio transmission.
, The power amplifier amplifies the sound of the remote audio
, The speaker outputs the amplified sound

System highlights
, simple operation
Shuntai Weicheng synchronous audio and video equipment adopts one-button simple operations such as recording and playback. Case handlers do not need training when they first come into contact with the equipment and can operate it flexibly
, fully High-definition image collection
Images, sounds and other information during the interrogation process are transmitted using digital high-definition signals from radio and television. The images are uncompressed and have full HD quality. All information is highly integrated and fully synchronized to ensure the authenticity and reliability of the evidence. sex.
Integration of remote equipment and synchronous audio and video equipment
Shuntai Weicheng synchronous audio and video equipment has a remote interrogation function. It can directly call and communicate with the video conference terminal through the protocol to achieve point-to-point remote communication. Additional remote devices need to be added.
, Echo cancellation, making speech clear
Shuntai Weicheng adopts full digital audio processing technology to support echo suppression and echo cancellation functions to meet the requirements of clear sound and no delay
, touch screen Centralized control to achieve intelligence
Shuntai Weicheng adopts touch screen interface control to control on/off, evidence switching and other functions with one button, saving case handling time and enhancing the evidence effect
and real-time uploading of audio and video Server management
Interrogation audio and video can be uploaded to the interrogation server in real time, which can realize unified storage management, data retrieval, etc. of the interrogation system
Remote command
Users can remotely and synchronously watch the information (inquiry) in real time through the network ) interrogation room scene scene, and can give text and voice commands to front-end interrogation (interrogation) personnel to coordinate case handling.
, multiple data protection
Supports simultaneous direct recording of dual optical discs and hard drives, independent backup of audio and video information on site in the interrogation room, and supports network and external hard drive backup at the same time. When an unexpected interruption occurs, When there is a power outage or failure, the recorded content will not be lost, protecting the safe storage of data information.
, Quick Disc Out
The disc can be output quickly, the disc output time is no more than minutes, and the burned disc data cannot be modified or deleted.
, supports multiple protocols and has strong scalability
The device adopts standard interface protocols such as .
