Dahua NVR Troubleshoot All Series, Network Video Recorder (NVR) is a specialized computer that records security video surveillance footage in digital format to a hard drive. Because the NVR does not have video capture capability, video is typically processed and encoded from the surveillance IP or CCTV camera and transferred to the NVR for storage via ethernet or WiFi network. NVRs are typically employed within IP video surveillance systems.
