USB and IP security Cameras
A USB webcam is a camera that connects to a computer, usually through plugging it in to a USB port on the computer.
IP camera connects directly to your network вroadband router in the conventional wired way using RJ-45 cable or wi-fi connection. IP camera is very reliable as it has separate operating system, just its own embedded program which is usually Linux based.
IP cameras are commonly used for video security surveillance but unlike analog CCTV cameras, they require only a local area network.
Most IP cameras are webcams, but the term IP camera or netcam usually applies only to those that can be directly accessed over a network connection, usually used for surveillance.
Some IP cameras require support of a network video recorder (NVR) to handle the recording and video analitycs. Others are able to operate in a decentralized manner P2P with no NVR needed, as the camera is able to record directly to remote storage.
