How Does a DVR Work?
Unlike an NVR system, DVR systems work with analog cameras, which can’t process video footage. Instead, the analog cameras stream raw video footage to recorders via coaxial cables. From there, the recorder processes the video footage. Once the video is processed, both DVR and NVR systems work the same.
