What is the difference between a DVR and an NVR?
DVRs and NVRs connect to multiple cameras and let you view and store the video files in one convenient place. For the most part, DVRs and NVRs serve the same purpose, but there are a few key differences, so it’s important to make sure you choose the recorder that meets your needs.
DVR: Lower price, less flexibility
DVR stands for digital video recorder; DVRs work with analog cameras (as in cameras that must connect directly to the DVR through cables). Because DVRs use wired cameras, the signal is more reliable, but the setup is harder and you don’t have as many options when you’re deciding where to put the cameras.
NVR: Easier camera setup, higher price
NVR stands for network video recorder; NVRs work with IP (internet protocol) cameras, which means the cameras can connect wirelessly. A big advantage of NVRs is that you get more flexibility when choosing where to place cameras. However, since the cameras are wireless, the signal is less reliable than it would be with a wired camera and DVR.
