Recording storage for your cameras: a WD internal hard drive for NVR and DVR recorders, and micro SD memory cards for Wi-Fi cameras that record on the camera itself.

Recording time depends on how many cameras you have, their resolution and whether they record all day or only on motion, so more cameras or higher resolution need more space. First check the maximum card or drive size your camera or recorder supports.
