CCTVFORENSICS.

CCTV forensics and forensic video analysis establish whether surveillance footage is original, who handled it and whether it was edited or re-encoded. The workflow seals the original, analyses a copy and reports measurements an investigator can defend.

[ 01 ]

Start with preservation

The original recorder export is hashed and written to write-once storage before anything is opened. Every later step works on copies and is logged.

[ 02 ]

Tampering evidence

Container and timestamp checks, compression-history analysis and temporal-consistency tests help show cuts, spliced segments and re-encoding. Many CCTV systems use unusual formats, so the report records what could and could not be parsed.

[ 03 ]

Reporting

Findings are placed on a timeline with parameters and software versions, so a second examiner can repeat them.
