Both a DVR and an NVR record video. They differ in where they process the video stream and in the type of camera each requires:
- DVRs are wired security systems that use analog cameras. They process and store video data at the recorder.
- NVRs can be wired or wireless systems. Most require IP cameras. NVRs encode and process video at the camera, then stream the
video to the recorder, which provides storage and remote viewing.
The appendixes document individual driver requirements and procedures.
