How Long Do Corporations Keep CCTV Footage?

CCTV systems play a crucial role in maintaining corporate security, particularly in banking and other high-security industries. One of the critical questions often asked is regarding the duration for which such footage is retained. According to the Reserve Bank of India (RBI), banks are advised to install CCTV cameras at the entry and exit of strong rooms and common areas of operation and are mandated to preserve their recordings for at least 180 days.

Storage Variations by Region and Institution

Besides the mandate from the RBI, the retention period of CCTV videos can vary based on legal requirements, storage capabilities, and specific policies of individual institutions. For instance, short-term storage might range from 30 to 90 days, while longer retention is typical for specific events or as per internal guidelines. The duration of retention differs from region to region, institution to institution, and can be governed by local regulations.

Common Retention Periods

Most standard banks store footage for 90 days after which they archive it using Tape Drive Libraries. This practice ensures that critical footage is retained for a long enough period to meet legal and security requirements. However, different banks may have different policies. For example, some banks may keep footage for 3 months, while others may extend the period to 6 months or even indefinitely. The decision often depends on the size of the server and the risk level associated with the property.

Storage Efficiency and Cost Considerations

Although it is common for banks to keep footage for 3 months, the actual storage configurations can be quite interesting. Many banks do not invest heavily in high-definition storage for their offices and branches, especially those with well-protected security vaults. This is because, historically, storage technology and associated costs were significantly higher than they are today. Therefore, most footage is stored at lower resolutions, typically 2 or 5 frames per second (fps), to save on storage costs and enhance efficiency.

Future Trends in Storage and Security

Although this storage and security practice has been the norm for some time, changes are on the horizon. As technology advances and storage becomes more cost-effective, it's expected that future banking operations will store higher-quality footage for longer periods than currently practiced. The overall goal remains to ensure comprehensive security while optimizing storage and cost efficiency.

Conclusion

The duration for which CCTV footage is retained is not a one-size-fits-all solution. It depends on a variety of factors including legal mandates, storage capabilities, and institutional policies. Banks and corporations must strike a balance between security requirements and operational costs. With evolving technology, it's anticipated that future trends will see improved storage practices and higher quality footage for longer retention periods.
