Network camera is a new generation of camera that combines traditional cameras with network technology. It can transmit video images to the other end of the Earth through the network, and remote viewers do not need any professional software, As long as a standard web browser (such as Microsoft IE or Netscape) is used, its video images can be monitored. Network cameras generally consist of lenses, image sensors, sound sensors, signal processors, A/D converters, encoding chips, main control chips, networks, and control interfaces.

The network camera is also called IP CAMERA (IPC for short), which is composed of Linear network coding module and analog camera. The Linear network coding module encodes and compresses the analog video signal collected by the analog camera into a digital signal, so that it can be directly connected to the network switching and routing equipment. The webcam is embedded with an embedded chip and adopts an embedded Real-time operating system.

Network cameras are a new generation product that combines traditional cameras with network video technology. The video signal transmitted by the camera is digitized and compressed by an efficient compression chip, and transmitted to a web server through a network bus. On the internet, users can directly view camera images on the web server through a browser, and authorized users can also control the actions of the camera's pan tilt lens or operate system configurations. Network cameras can achieve simpler monitoring, especially remote monitoring, simpler construction and maintenance, better support for audio, better support for alarm linkage, more flexible video storage, richer product selection, higher definition video effects, and more perfect monitoring management. In addition, IPC supports WIFI wireless access, 3G access, POE power supply (network power supply), and fiber optic access.

IP network camera is a digital device based on network transmission. In addition to the ordinary composite video signal output interface BNC, the network camera also has a network output interface, which can directly connect the camera to the local LAN.
