The DVR vs. the NVR - what's the difference?
DVR stands for digital video recorder, and it is a device that records video from a security camera or other video source. It typically has a hard drive that stores the recorded video, and it can be used to playback the video footage.
NVR stands for network video recorder, and it is a device that stores video footage on a network server. It can be accessed remotely from anywhere on the network, and it can also be used to record video from multiple cameras.
DVRs and NVRs both have their own advantages and disadvantages. DVRs are typically less expensive than NVRs, and they are easier to set up and use. However, NVRs offer more features and flexibility, and they are better suited for large-scale security systems.
