Part II: Casino Operations · Surveillance & Security

Evidence Preservation

Investigation

The process of securing and maintaining video recordings, documents, physical items, and other materials that may be relevant to an investigation, legal proceeding, or regulatory matter. Evidence preservation in surveillance includes creating unalterable copies of video with embedded timestamps, securing original recordings against overwrite or deletion, documenting the preservation process, and maintaining the preserved evidence in a secure environment with restricted access.

In practice

Upon notification of an incident, surveillance must immediately flag relevant footage for preservation to prevent automatic deletion based on standard retention cycles.
