Video Evidence Recovery and Analysis (VERA) Course
Level - Intermediate
Course Length: 5 Days
The Video Evidence Recovery and Analysis Course (VERA) is five-day intermediate level course designed to introduce investigators, examiners and analysts to digital video technology and to meet the specific needs of the digital video examiner and analyst.
Students will learn proper methods to interrogate digital video evidence while receiving guided instruction throughout the process of recovering valuable evidence from video images. The course will also focus on specialized investigative techniques for the examination of video to explore issues relating to the use of force, speed estimation and identification. A variety of DVR, body-worn and in-car video sources will be examined in depth, testing data acquisition, file identification, image accuracy, video processing work flows and report writing.
The course will provide students with an understanding of best practices and methodologies for extracting and examining digital media evidence while providing students with focused, practical use of DVR Examiner and iNPUT-ACE. Upon successful completion of the course, students will be offered an opportunity to take an industry-recognized certification examination, created in partnership with DME Forensics and iNPUT-ACE.
Upon successful completion of this course, the student will be able to:
• Understand video standards, frame rates and aspect ratios.
• Recognize compression, codecs, file formats and containers
• Understand Digital Video Recording devices and technology
• Demonstrate Best practices and methods of video extraction
• Accurately document video extractions
• Cellebrite's core training and certification process.
• Cellebrite's accolades and accomplishments.
• Recognizing the current tools and solutions used in digital investigations.
• The legal responsibilities of investigators conducting digital investigations.
