Record duration refers to the amount of time a surveillance system can store video footage. It depends on several factors, including storage capacity, resolution, frame rate, and compression format.
For example, higher-resolution video uses more storage, which can shorten the total duration. Conversely, using efficient compression like H.265 extends recording time without needing extra space.
Security teams calculate record duration to ensure footage is available when needed. In many cases, regulations require video retention for a specific number of days.
Therefore, selecting the right settings and hardware helps balance quality, compliance, and storage limits.
