The length of time that your recordings will be stored for depends on your system and your settings. The most important factor is the size of the hard drive.
Since our recorders are designed to constantly replace the oldest footage with newest footage, the size of the hard drive greatly determines how long recordings will be stored for. Other settings, such as the number of cameras, resolution, and frames-per-second rate, as well as scheduled and motion-triggered recording options, can also extend your recording times.
