What is IP Surveillance?
IP-Surveillance is a term for a security system that gives users the ability to monitor
and record video and/or audio over an IP (Internet Protocol-based) computer network
such as a local area network (LAN) or the Internet. In a simple IP-Surveillance system,
this involves the use of a network camera (or an analog camera with a video
encoder/video server), a network switch, a PC for viewing, managing and storing video,
and video management software.
Unlike analog video systems that use dedicated point-to-point analog cabling from the
camera location to the viewing/recording station, IP-Surveillance (or network video)
uses the IP network technology as the backbone for transporting information. In an
IP-Surveillance application, digitized video and/or audio streams can be sent to any
location, even around the world, if desired, via a wired and/or wireless IP network,
enabling video monitoring and recording from anywhere with network access.
While an analog video system is for the most part a one-directional signal carrier that
ends at the recording device, a network video system is bi-directional (allowing
information to be sent and received) and can be an integrated part of a larger, scalable
system. A network camera, for instance, can send video and audio to a user, as well as
receive from the user audio and data instructions that could, for example, activate
doors or external alarms. In addition, a network video system can communicate with
several applications in parallel and perform various tasks such as detecting motion or
sending different streams of video. Such a system provides for greater performance
possibilities and flexibility.
