1.1 Network Cameras
Network cameras are closed-circuit television (CCTV) cameras that use the
Internet Protocol (TCP/IP) to transmit image data over an Ethernet or Wireless
LAN connection. As such, network cameras are also referred to as IP cameras.
IP cameras are primarily used for surveillance applications. A number of IP
cameras are normally deployed together with a digital video recorder (DVR) or
a network video recorder (NVR) to form a video surveillance system. Since
network cameras are equipped with an operating system, they do not require
the presence of a DVR or NVR in order to function. In addition, a network
camera can transmit data in a local network as well as over the Internet.
Access to a network camera is typically achieved with a standard Web browser,
such as MS Internet Explorer or Firefox.
