Depending on your country or jurisdiction, there may be specific regulations regarding the retention of footage. For example, in the United States, some states require businesses to retain security camera footage for a certain period of time, usually ranging from 30 to 90 days. It is important to familiarize yourself with these regulations to ensure compliance.
Individual security preferences and purposes
Apart from legal requirements, individual security preferences and purposes also influence the retention period. Some individuals or businesses may prefer to retain footage for longer periods for security reasons or for future reference. Others may choose to keep footage only for a shorter period due to limited storage capacity or privacy concerns. Understanding your specific security requirements and reasons for retaining the footage will help determine the ideal retention period.
Practical limitations and available resources
Practical limitations, such as storage capacity and available resources, need to be considered when determining the retention period. If you have limited storage space, you may need to overwrite older footage sooner. Additionally, the cost of storage solutions and the available budget will also impact the retention period. It is important to strike a balance between practical limitations and your security needs.
