Introduction
Networked video is today's generation in video surveillance and can provide numerous advantages over analog and digital video recorder based systems. Networked video systems (NVS) are developed to utilize Internet Protocol (IP) enabled devices such as computers, network switches, IP cameras. Internet Protocols are a collection of standardized and globally accepted protocols for information transmission through a network. IP networks are safe and have been in use with other applications since 1974. A firewall, VPN (virtual private network) and password protection restrict access to data being stored and transferred. In addition, video camera manufacturers have encryption and IP filtering built into their cameras to help provide an added layer of protection.

Technology and Terminology:Internet Protocol (IP) is a term used for any application or software program that is developed using a set of computing standards which allows data to be transferred over the Internet. In technical terms, the data is communicated over the Internet via a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP/IP.
Networked video is called the today's generation of CCTV video surveillance because it uses both private (Ethernet, LAN) and public (Internet) networking to allow access to real-time video. By using proper security credentials, video feeds can be viewed by authorized viewers anywhere there is an Internet connection.
Networked Video Management Systems (NVMS) and Networked Video Recorders (NVR) can either serve the same function or different functions depending on the size of the video network. Enterprise systems may add an NVMS in order to provide a single graphical user interface (GUI) to monitor, record, and analyze functionality and therefore deliver the timely, accurate information required for effectively responding to any challenge. In smaller, more compact networked video systems, the NVR serves this function. Basically an NVR is similar to a networked video DVR but offers more robust functionality and other substantial advantages.
