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.
