Understanding the difference between DVR and NVR is essential when evaluating security systems. In this article, our security experts will break down the differences and detail the pros and cons of each so that you can make an informed decision.

NVR vs. DVR – The Basics

At the core, both NVR and DVRs are responsible for video recording. DVR stands for Digital Video Recorder, whereas NVR stands for Network Video Recorder. The difference between NVR and DVR is how they process video data. DVR systems process the video data at the recorder, whereas NVR systems encode and process the video data at the camera, then stream it to the NVR recorder which is used for storage and remote viewing. As DVRs and NVRs handle the video data differently, they require different types of cameras. Most NVRs are used with IP cameras whereas DVRs are used with analog cameras. It’s important to note that a DVR based system is a wired security system, whereas NVR systems can be a wired or wireless system.
