Why storage is so important
Many people first look at camera resolution, but storage determines whether you can later prove something. Watching live is convenient, but in incidents you want to be able to look back: when did it happen, which camera saw it, and how long will the footage remain available?
Therefore, we always discuss recording during advice. It matters whether you only want to view notifications, want to record continuously, or want to store images for several weeks. That choice determines the recorder, storage space, and sometimes also the type of camera.
