Traditional CCTV installations

Traditional surveillance (CCTV) cameras are usually

connected to a monitor, using dedicated coaxial cabling.

Where a multiplexer is used, several cameras can be

displayed on a single monitor.

It is relatively easy to add one or two more monitors

within a building. Viewing images from additional out-

side locations becomes progressively more complicated.

That is because dedicated cable is required to add a new

monitor or camera to any existing system. In addition

to this, CCTV users must always consider how to handle

the storage of large quantities of magnetic tape.

A typical CCTV system comprising analog cameras, multiplexer, monitor and time-lapse recorder.

Upgrading existing CCTV systems

using network video products

A PC installed with professional network video applica-

tion software is connected to the IP network in order to

retrieve, manage and replay digital video from all the

system’s cameras. Digital video is stored on an external

hard disk, directly on a resident PC, or to any dedicated

server over the network. The ﬂ exibility and scalability

of network video solutions enables convenient, piece-

meal upgrades to be made from an existing analog to a

new digital system.

A typical surveillance conﬁ guration using network cameras. All cameras

can be seen and managed from any computer on the network. It is possible

to extend viewing and management access to include any remote PC in the

home or ofﬁ ce.

An Axis video server connects to existing analog cameras to digitalize and

transmit the video over the IP network.
