How should CCTV footage be handled to preserve integrity?

• A. Log access, maintain chain of custody, avoid altering footage, and ensure proper storage and restricted access
• B. Randomly rename files for easier retrieval
• C. Share footage with any party requesting it
• D. Delete footage after 7 days automatically

Answer: (A)

Preserving the integrity of CCTV footage hinges on creating a defensible, auditable trail for every handling of the footage. Start with logging every access—who viewed it, when, and for what purpose—to establish clear accountability. The footage itself must be kept with an unbroken chain of custody, documenting every transfer, copy, or examination so there are no unexplained gaps. Never alter the original material; use only verified copies and consider using hash checks to detect any changes. Storage should be secure and restricted, with proper access controls, encryption where appropriate, reliable backups, and tamper-evident measures. These practices help ensure the footage remains trustworthy as evidence and meets legal and investigative standards. Renaming files randomly undermines traceability and makes it hard to establish which copy is the original. Sharing footage with any party compromises confidentiality and the custody trail. Deleting footage after a short period eliminates potential evidence and may violate retention policies.
