IP camera, or Internet Protocol camera is also called Network Camera, and they are widely used for residential and commercial purposes, offering the user high quality.
IP camera needs a static IP address for the router and other network devices to identify and connect with it. In case of a dynamic IP address that keeps changing randomly every time the camera is connected to the network, a fixed URL via Dynamic Domain Name Service (DDNS) must be set up.
IP cameras either have wired or wireless connections, and are used both indoors and outdoors, during the day and at night.
There are two kinds of IP cameras:
Centralized IP cameras
These cameras require a central NVR to store the recording, handle video and alarm management.
Decentralized IP cameras
Decentralized IP cameras don’t need a central NVR, and the video is processed at the source, as the cameras have recording function built-in and can thus record directly to any standard storage media, such as SD cards, hard disc, or a server.
