The storage space requirements depend on the camera’s image resolution, frame rate, compression ratio and days of retention.

2.) What Is A Camera Retention Time: A security camera can store a large number of recordings which depends on the images captured per second, video compression ratio, and the image size. Usually, a security camera offers only limited storage space because of which past recordings are saved for a preset amount of time before they are overwritten by new recordings.
