How long should we retain CCTV and security camera footage from a secure or restricted-access area?

There is no single universal retention period for security camera footage. The right answer depends on why the footage exists, what risks it documents, and which legal authorities apply to your organization. Surveillance video is a record, and like any record it should be governed by a retention schedule rather than left to fill a hard drive until it overwrites itself.

Start With Purpose and Authority

Footage from a secure or restricted-access area usually exists for routine operational reasons: monitoring access, deterring intrusion, and supporting incident investigations. For that ordinary, day-to-day footage, most organizations retain it for a short, fixed window, then let it overwrite automatically.

Two questions drive the period:

• What schedule applies? Federal agencies generally cover physical-security and surveillance recordings under an established records schedule. Check whether a government-wide schedule already prescribes a period before creating your own. State, local, and private organizations should look to their adopted retention schedule and any sector-specific rules.
• What is a defensible routine period? A common practice is to retain general surveillance footage for a relatively short interval (often measured in weeks to a few months) sufficient to detect and review incidents, then dispose of it consistently.

When the Clock Changes

Several triggers should override the routine period and require you to preserve specific footage longer:

• Incidents and investigations — video tied to a security breach, accident, or criminal matter should be segregated and retained under the applicable case file or evidence rules.
• Litigation holds — once litigation is reasonably anticipated, suspend deletion of relevant footage immediately.
• Open-records or FOIA requests — preserve responsive footage until the request is fully resolved.

Privacy and Disposal

Surveillance footage may capture identifiable individuals, so retention should be no longer than necessary for its stated purpose, consistent with privacy principles like those underlying the Privacy Act. Document your retention decision, apply it consistently, and dispose of footage through an approved, logged process so deletion is routine and defensible rather than ad hoc.
