How long do supermarkets keep CCTV?

Depending on an organisation, CCTV footage may be required for trend analysis, investigation, auditing and retrieval.

In as supermarket situations, CCTV can be used for trend analysis as well as for investigation. Depending on the use of the CCTV, the footage can be kept as long as the organisation and the data company providing the services deems necessary.

For instance, if a supermarket uses CCTV for an investigation or auditing, such footage may be kept for as long as they wish. On the other hand if used only for trend analysis, such footage may be kept for only a day or as a long as a month.
