Video Forensics System

1. Requirement Analysis

 

With the construction and development of the city, surveillance system plays an unprecedented role in the security protection systems. Usually the surveillance system captures and carries a huge amount of video, audio and image information, and all the information can tell a lot in obtaining clues of the case, and discovering the digital evidence. The other videos which are stored in the mobile phone or computer are of similar importance. When a criminal activity, a violence or terrorism incident occurs, we can get valuable information or intelligence by extracting and analyzing the related videos. Therefore, a professional, integrated and authenticated video forensics system is becoming urgently necessary.

 

2. System Introduction

 

Video Forensics System (hereinafter as VFS) is a forensically sound system for video extraction, recovery and analysis. Through VFS, it helps clarify the visual evidence and restore the truth rapidly.

 

 

 

3. System Functions

 

3.1 Video Extraction and Recovery

  • Support video extraction of Fat32, exFat, NTFS, JFS, EXT2/3/4 and other file systems
  • Video files can be extracted by channel and time
  • Support quick data imaging from source disk into file
  • Footage Restoration

 

3.2 Video Playing
