What constitutes 'chain of custody' for CCTV footage?

• A. Copying footage and renaming files
• B. Allowing anyone to access footage without logs
• C. Deleting footage after use
• D. Documenting access, maintaining logs, preserving original footage, and restricting access

Answer: (D)

Chain of custody for CCTV footage is about preserving the evidentiary integrity by tightly controlling and documenting every handoff and access to the file. The best answer includes documenting who accessed the footage, when, and why; maintaining logs that show a complete access trail; preserving the original, unmodified footage (and using verifiable copies only when needed); and restricting access to authorized personnel. This combination ensures the footage can be trusted as evidence and that any changes or mishandling can be detected. Copying footage, renaming files, or letting broad access with no logs breaks that trail and risks questions about authenticity. Deleting footage eliminates potential evidence and undermines the chain of custody.
