The only difference is that, NVR as compared to DVR records the videos directly from the network. It is a consumer electronic device, which is used for recording the videos in live mode. 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. The biggest differences for DVRs vs NVRs are the cameras and cables they use. Conversely, digital video recorders gain their video feed from HD analog cameras with coaxial cables. A network video recorder records footage from HD IP camera either via Ethernet cables (PoE) or wirelessly (for WiFi IP cameras).

An NVR works like a computer program as the device inputs off the network.

It is the IP camera that does the encoding and processing. A DVR relies on analog cameras linked by a coax cable. An NVR utilizes IP cameras using a network cable. By contrast, the DVR is not only a storage media for analog CCTV cameras but also a video processor that analog cameras must live with.

But with an NVR , due to its very nature of being on a network, you can view it remotely. Video on a DVR is encoded and processed at the DVR , while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing. An NVR is a software program that records video in a digital format to a disk drive , USB flash drive , SD memory card or other mass storage device. Another difference between a DVR and an NVR is access. DVRs are mainly used for recording semi-digital or analog cameras or coaxial-based cameras.

When people ask what is the difference DVR and NVR , it can be summed as follows. A DVR is a video processor that works with CCTV analog cameras and also functions as storage. For you to finally see the difference between the NVR system and DVR system, take a look at the following: With the network video recorder, the video output will obviously come from the network as the video is already encoded at the cameras. A digital video recorder inputs data straight from the cameras.

In DVR, you can record uncomfortable videos using cabling and connectors. The DVR system works with analog cameras. The term DVR refers to a recorder that records a video signal from an analog feed via coaxial cable.

A big advantage of NVRs is that you get more flexibility when choosing where to place cameras.

Digital in DVR means it is recording to a hard drive. However, since the cameras are wireless, the signal is less reliable than it would be with a wired camera and DVR. To learn more about the digital and network video recorder and reach a final decision on DVR vs. Cons: All cameras have to connect to the NVR , once the NVR fails or malfunctions, the entire system fails too.

Analog cameras can not be accessible online. Be compromised by cutting or accessing the physical wires of the system, and the signal is not encrypted to keep it safe from unauthorized viewing. This is the main difference between the DVR system and POE NVR system. DVR is able to connect many of our other analog cameras or other analog cameras not from us.

But POE NVR is only able to connect the one POE IPC model. POE IPC is only able to connect the one POE NVR model.
