Requirements for video storage time

Different industries have different requirements for video storage time. The less time is only 1-2 days and the more time is up to 30 days. The public security industry also has different storage time lengths in different regions, so the Ministry of Public Security made a unified specification for this time in the "Urban Monitoring and Alarming Networking System Through Technical Requirements": more than 15 days. Some insurance companies have unified regulations across the country: more than 7 days. The above time requirements are only used as a reference for business promotion, and the specific requirements also need to be determined according to the business needs and economic capabilities of end users.
