Existing Analog CCTV Networks. Where

eployed, operators can easily add IP-based systemso augment the capabilities. There is no need to incur

based systems can complement the existing

network via a video encoder that is discussed later

Common Architectural Ground

majority of video surveillance systemswhether

analog or IP-based have a number of common

network architecture elements.

Command and Control Center. The Command

and Control Center provides system operators with

the ability to view real time video, control camerasand archived video images. These images are com-

monly displayed on many monitors simultaneously

Command and Control Center.

The Center provides system users with the network

connectivity to the network and associated cameras,

enabling network operators to provision, monitor

and control the underlying elements of the video

surveillance network. The Center is commonly

equipped with network management servers,

switches, routers and firewalls, and used to man-age the connectivity infrastructure that supports the

network and the communications infrastructure

may use common servers, routers, sw tc es or

other components.

Video Cameras. Video cameras are distributed where

required throughout the network to collect information

and pass it to the network. Typically, enterprises have

deployed analog CCTV video cameras that are connected

via a coaxial cable to a video encoder that provides

images to the Command and Control Center. When

onsidering a video surveillance network architecture,

it is important to bear in mind the inherent advantages

f IP cameras. Since IP cameras can be connected

irectly to an IP network, an encoder is not required.

Streamlined Wireless Extensions

for the central office, but now needs to have video

surve ance at a remote or unmanne ocat on across

istant from the Command and Control Center, it isifficult and time consuming to establish new coax a

network operator require an extension to the existing

CCTV network as well as existing analog cameras, an

IP-based wireless infrastructure solutioncan easily be

esigned to extend the network through the use of

n encoder to make IP connectivity possible.Although

nalog-based systems are proven to work in many

pplications, there are many others in which they are

Extending IP-Based Systems. xten ng a v eo

surveillance network is an excellent opportunity to

leverage the benefits of a wireless IP-based video

network. In general, these extended solutions place

IP cameras exactly where surveillance is needed.

In an IP-based system, cameras are connected

through a Point-to-Multipoint and Point-to-Point back-

haul network that connects to servers located

at t e networ center.

e n s transport t e ata across ong

stances etween t e networ center an t e

The PMP networks then distribute the available

bandwidth to cameras positioned throughout the

operating area.

The PMP networks are composed of Access

Points (APs) and Subscriber Modules (SMs).

The Ethernet connection from the wireless network

is an industry standard RJ-45 connection thatconnects directly to the IP cameras. The wireless

infrastructure can also provide secure and reliable

connectivity to network clients in the Command

and Control Center.

Combining Analog and IP Solutions. n some ap-

plications, network operators may want to add video

overage to a new location such as another city or

region - that is distant from the Command and Con-

tro enter. n t ese cases, t e operator can eas y

be used to provide connectivity for individual cam-

Point-to-Multipoint & Point-to-Point Solutions.

Wireless networks can be used to create connectiv-

provide wireless connectivity to a large number of

Subscriber Modules (SM) distributed throughout a
