What's The Difference Between A Network DVR or NVR?

A Digital Video Recorder or otherwise referred to as a DVR is analog and/or IP based recorder, which is a consumer electronic device or application software that records video in a digital format to a disk drive such as an USB flash drive, SD memory card or another local or networked mass storage device.

Many are designed to record audio too, whether at the camera or as a separate apparatus in an isolated area. In some DVR security systems, the user can remotely access the security footage by using a PC, Smart Phone, or tablet so they can see the real time live footage. This can also be achieved by connecting the DVR to a LAN network that has an internet service.

A Network Video Recorder, which is also known as a NVR is different from its predecessor the DVR. An NVR is not restricted by location and therefore doesn't have to be in the same area as your cameras cabling, which is a big advantage if you have your business or work in another place.

With this advantage it means the NVR can be placed anywhere, all that is required is that it is on the same LAN network as the IP based cameras. This is what makes a network video recorder noticeably different from a digital video recorders as well as their input is assigned on a network rather than a direct connection to a video capture card.

To put it simply, video on a DVR is encoded and processed on the DVR, while video on an NVR is encoded and processed on 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 and in this way an NVR contains no dedicated video capture hardware. The NVR’s software is typically run on a dedicated device, usually with an embedded operating system.
