17. Video Surveillance Bandwidth requirements
Number of Cameras/streams
Camera Intelligence that includes:
Built-in motion detection to reduce bandwidth utilization
Image size/resolution
Common Intermediate Formats (CIF) (Horizontal x Vertical resolution)
Older D1(720*576 for PAL), Half-D1(720*288)
Frame rate supported at full resolution
PAL format : 25 Frames/s,
NTSC format (used mostly in North America) : 30 Frames/s
Compression algorithm
A function of delay, quality requirements and available bandwidth and storage
For example, 4CIF/PAL uncompressed is just over 10Mbps but with MPEG-4 it is
reduced to 2Mbps
Format Video Resolution
(H * V)
SQCIF 128 × 96
QCIF 176 x 144
CIF 352 x 288
4CIF 704 x 576
16CIF 1408 x 1152

23. Summary
FINANCE: Telecom and IT infrastructures can be shared, which saves CAPEX & OPEX!
NETWORK : Ethernet is being adopted for a wide range of Industrial Applications
specifically for Video Surveillance and can be built for
Scalability
Resiliency
OPERATIONS: Using today’s technologies, you can provide real time images that can
be accessed from anywhere at anytime
By using integrated video surveillance technologies, customers’ safety and security is
ensured with better performance and low cost
24. Key Advantages of Video Surveillance using today’s Digital Technology
Future-proofing through
interoperable components
Reduced Total Cost of
Ownership through IP Networking
Advantages
Lower Installation Cost
Better video quality and
other value-added features
• Digital cameras can be connected and powered by PoE
• Multiple cameras can use the same cable
• Changing camera placement is simple – just remove and plug into
another network jack
• Cameras can be placed almost anywhere and then accessed via desktop
computer, laptop, PDA and even cellular phone
IP video surveillance systems scale easily from one to thousands of cameras
in increments of a single camera
• Cameras have IP addresses just like any other network device you already have
• IP networking enables you to leverage existing infrastructure such as servers,
switches and cabling
• There is no need for complicated proprietary hardware and dedicated monitors
• IP networking eliminates the need for a control room at each location
Live camera feeds can be accessed over the Internet from any location
• Freedom of choice in hardware, software, and other components.
• The digital I/O is convenient to integrate with other security equipment
like lighting, gates and doors.
• The ability to integrate through the network with other business systems,
such as ATMs, ERPs, and POS systems, etc.
• Less expensive and time-consuming of redundant and replacement
systems
• Greater availability of powerful software management tools for
monitoring, accessing and storing video
• Digital cameras provide up to 16 times the resolution of traditional analog cameras
• Camera manufacturers are focusing on innovative and advanced digital camera features
while interest in analog cameras wanes
• Fast search and retrieval capabilities
• Intelligence at the camera level can include detection of motion, identification,
• Digital cameras can save and send the images collected before an alarm occurred and the
alarm put the camera in record mode
• Easier to monitor & manage cameras just like any network device
25. Bandwidth Needs and Network Segmentation
Operator selecting a CCTV camera stream
• Centralized and/or distributed
• M cameras in parallel * Y Mb/s -> 1 GE to 10GE
Storage
• N cameras in parallel * y Mb/s -> could go up to 10GE access to the
network
Build a routed core to route the traffic to the receiver
• Flexible
• Only route requested video stream through the core
Build an access layer to aggregate the camera streams
• 10/100 Mb to 1G uplink
Build a layer 2 aggregation network to aggregate the
different access network to the core

Cellular Roaming
Wireless roaming patterns differ in normal vs. transit case
▼ In a WLAN environment the user
moves from one cell to another in
any direction
▼ In a transit WLAN the user moves
from cell to cell in a linear manner,
thereby providing a means to
extend cell size by using
directional high gain antennas
