Fast & Easy Deployment of a Cost-Efficient
Infrastructure
The majority of businesses now have high-speed, IP-based networks connected
to the Internet. Adding a network video system simply utilizes and extends
the same infrastructure to include video functionality. IP-Surveillance
solutions utilize a normal IP-based network for transmitting and distributing
video, thus eliminating the need for costly, time-consuming dedicated
cable installation. Under these circumstances setting up a network video
system is both simple and cost-effective.
The only action required is to set the IP addresses of the network video
products. Once the basic system is up and running, it can be fine-tuned
in a number of ways: by adding other functions such as motion detection,
alarm handling, time stamping, local programmability, digital inputs and
relay outputs, and Pan-Tilt-Zoom control - all communication running over
the IP network, there is no need for additional cabling.
The Network Camera
A Network IP Camera is a self-contained camera and processor. The user
can use a standard web browser to view live, full motion video from anywhere
on a computer network, including over the Internet. This is a more economical
alternative for many businesses and organizations than high-priced Closed
Circuit TV (CCTV) systems. Installation is simplified by using existing
LAN wiring and/or wireless LAN. This eliminates the expense of installing
additional cabling. Features such as motion sensing with e-mail notification,
simultaneous user login, and FTP upload capability further differentiate
the device from current video technology.
Analog Versus Digital Surveillance Systems
With an CCTV analog surveillance camera, the analog video signal is sent
through a coaxial cable to a video recorder or monitor. One cable can
transport only one video signal from one camera at a time. If you have
two cameras, you need two cables.
With an IP-based network camera, the network camera immediately digitizes
the images and the video stream is ready to be sent over any computer
network available. One network cable can easily handle signals from two
network cameras simultaneously. In fact, one standard UTP network cable
can forward images from more than 220 network cameras simultaneously,
without becoming overloaded.
Bridging the Technological Gap
IP-Surveillance technology offers more cost-efficient, future-proof solutions
that bridge the technological gap between the analog and digital worlds.
Video servers, for example, can be integrated into an analog CCTV system
to digitize analog video sources and distribute digital video over an
IP network -- essentially turning analog cameras into network cameras.
A major advantage of using a video server in an analog system is the
ability to access real-time video remotely, via an IP network. Live video
can be accessed by authorized personnel at any defined workstation on
the network, or over the Internet. Additionally, video servers can, using
built-in serial ports, control equipment such as Pan/Tilt/Zoom cameras,
or special cameras such as super sensitive black/white cameras, miniature
cameras and microscope cameras. Furthermore, inputs, such as alarm events,
can be used to trigger the server to start transmitting images. Servers
equipped with image buffers can also send pre-alarm images.
Camera video server solutions are ideal for sharing high-quality video
streams over existing computer networks. Superior to analog video solutions,
IP-Surveillance means reliable and distributed access or recording of
high-quality digital images, and improved functionality and cost.
