Product Details:

In the traditional analog CCTV application, security cameras capture an analogvideo signal and transfer that signal over coax cable to the Digital Video Recorder (DVR). ... When broadcasting over the Internet, the video for all of the cameras is transmitted as one stream (one IP address). Therefore, it is very efficient.

A digital video recorder (DVR) is a consumer electronics device designed for recording video in a digital format within a mass storage device such as USB flash drive, hard disk drive or any other storage device. Compared to other video recording alternatives, a digital video recorder has many advantages such as being tapeless, faster data retrieval and higher image quality. It is mostly used in home entertainment and in surveillance/security systems. Digital video recorders are also known as personal video recorders (PVR).

Whereas in a traditional DVR, the video files are encoded (changed from video feeds to files) in the DVR; with NVRs, the video is encoded and processed in the IP Camera and then sent to the NVR to be saved, viewed, and stored. NVRs do not have video capture cards but usually have sophisticated (or multiple) Ethernet ports.

Often NVRs are mistakenly called DVRs, but they are different.

NVRs work with IP (Network) Cameras; rather than BNC based (Analog, AHD, CVI, TVI, and SDI) security cameras.

Network video recorders are distinct from digital video recorders (DVR) as their input is from a network rather than a direct connection to a video capture card or tuner. 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. Additional processing may be done at the NVR, such as further compression or tagging with meta data.

Hybrid NVR/DVR surveillance systems exist which incorporate functions of both NVR and DVR; these are considered a form of NVR.  

NVR home surveillance systems are generally wireless, tend to be easy to set up, can be accessed through a web browser, and allow the user to be notified by email if an alarm is triggered.

An Internet Protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed-circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet. IP network cameras of all styles are stocked, including dome, bullet, body, fisheye and PTZ. RF Concepts offer Internet Protocol cameras ranging from 1080P / 2 megapixel up to 12MP, with features including PoE. IP cameras and smart home cameras can be accessed via mobiles or tablets for remote viewing and monitoring.
