The primary distinction between a network video recorder (NVR) and a digital video recorder (DVR) is how raw video data is processed. A DVR transforms analog video to digital format, but an NVR normally only works with digital video.
Data is processed at the recorder in DVR systems, whereas data is encoded and processed at the camera before being transmitted to the recorder for storage and remote viewing in NVR systems. Unless otherwise specified, the DVR links to an analog CCTV system through coaxial cable, whereas the NVR connects to an IP camera system via Ethernet or WiFi.
DVR vs. NVR-Compare the Basis
Both NVRs and DVRs are in charge of video recording at their core. The terms DVR and NVR stand for Digital Video Recorder and Network Video Recorder, respectively. The processing of video data differs between NVR and DVR. NVR systems encode and process video data at the camera, then stream it to the NVR recorder for storage and remote viewing. DVR systems process video data at the recorder, whereas NVR systems encode and process video data at the camera.
DVRs and NVRs require different types of cameras since they process video data differently. NVRs are typically used with IP cameras, while DVRs are typically used with analog cameras. It's worth noting that a DVR-based security system is a wired system, whereas NVR systems can be wired or wireless.
In Summary
The cost, how the data is transferred, and the type of cameras are the main differences between DVR and NVR systems. NVR systems feature superior picture quality, are quicker to set up, have more flexibility, and native audio capabilities on every camera with a microphone. NVR systems, on the other hand, are typically more expensive than equivalent DVR systems, which is a crucial factor for budget-conscious consumers.
A DVR system will most likely suffice for anyone searching for a simple security system, especially if your house is already wired for a coaxial connection from an existing security system. An NVR-based system is the best option if you need a top-of-the-line, highly versatile solution. At the end of the day, the deciding element will be your property's unique security requirements.
