H12-511: HCIA-Intelligent Vision

DVR camera capacity and NVR camera capacity depend on the recorder model and its specifications. DVR systems conventionally use analog cameras and convert the incoming analog footage to digital form for recording and storage. NVR systems use IP cameras, which encode video at the camera; the NVR receives, records, and stores that digital footage. Thus, both types store video, but only the DVR must encode the analog input for storage.
