Solutions | IP Security and Surveillance
Video surveillance and security has moved to the forefront
globally as a strategic tool in protecting corporate assets, the
war against terrorism, crime prevention, and public safety. At
the same time, video surveillance usage is increasing as a tool
for trafc monitoring and local government security. The days
of grainy and blurry analog CCTV systems have been replaced
by advanced digital IP cameras and systems producing highresolution, high-denition, real-time video. Along with that new
technology, the high-speed IP networking infrastructure enabling
it is critical.
Video Surveillance Technology Advancements
The new-generation IP-based video technologies displacing
analog CCTV systems use high-denition, high-megapixel
cameras and high-quality lenses to produce full-motion, real-time
video. The requirement to have clear, high-resolution, real-time
video demands high-speed IP to ensure uninterrupted quality.
An IP video surveillance system consists of multiple cameras
connected to video storage servers recording and processing
video streams, and an operations center or hub where video is
displayed and monitored on a real-time basis. Many IP security
cameras feature 360-degree pan-and-tilt capabilities controlled
remotely from an operations center. To support the IP video
network and enable remote camera control and operation, a
high-speed IP/Ethernet network is required with its design and
functionality tailored to IP video applications.
IP security cameras are used in nearly every type of facility and
application: on streets, on building exteriors, inside buildings and
hallways, in parking lots, and so on. There are many types of
xed or adjustable cameras suited for many applications. They
serve the needs of military, government, utilities, corporate,
medical, retail, hospitality, transportation, and education and
more. To serve the wide variety of needs and applications,
whether indoors or out, a reliable high-speed IP network is
needed to connect cameras, servers, and the operations center
where monitoring occurs, whether inside a building or atop a
roof or trafc light. The range of applications, environments, and
even the types of cameras used, all dictate the need for adaptive
IP/Ethernet networking infrastructure scalable to and optimized
for the specic requirement. A “one solution ts all” approach
lacks the robustness and economic efciency to solve the range
of applications required of IP video surveillance.

Allied Telesis Provides the IP Connection
Allied Telesis was founded in 1987 as an IP/Ethernet technology
company, and has been pioneering IP access edge solutions
for enterprise and carrier markets globally for more than 20
years. As a result, Allied Telesis brings to the market a diverse
family of more than 1,000 IP/Ethernet products including media
converters, PC NICs, Layer 2 and 3 Ethernet switches, routers,
integrated Multiservice Access Platforms (iMAP™), and intelligent
Multiservice Gateways (iMG).
Allied Telesis has been a leading innovator in IP video, designing
advanced Ethernet switches, multiservice gateways, and carrier
access products to be IP video-enabled and -capable. In fact, the
rst commercial deployments of IPTV services in the world used
Allied Telesis as the platform. Allied Telesis brings both the video
exper tise and complete range of IP functionality necessary to
deliver the highest-quality IP high-denition video possible.
IP video sur veillance and security systems require network
equipment at the camera sites, server/data center, as well as
the monitoring center. Allied Telesis offers a range of products
and technologies functionally and economically designed
for each location to enable the creation of a complete endto-end network solution. Product selections include units
environmentally hardened for use in outdoor locations, as well
as hub and aggregation equipment. In addition, Allied Telesis
offers a unied management approach with its AlliedView
NMS, allowing an operator to congure, monitor, diagnose, and
manage every part of their security network with Allied Telesis
intelligent devices.
™
The Importance of IP Video Functionality
IP Multicast (IGMP)
IP multicast is based on the Internet Group Management
Protocol (IGMP), and is designed to allow one video source to
broadcast video to multiple hosts as a single instance, thereby
conserving bandwidth. IGMP uses a series of “join” and “leave”
messages to allow clients to receive video and notify the host to
broadcast it. IGMP operates with group IP addresses, using an
address range specically designated for video multicast. IGMP
can be congured for either a Layer 2 bridging function (IGMP
snooping) or Layer 3 routing using VLANs (IGMP proxy routing).
Multicast is most often used between servers and clients, such as
a NOC center.
Allied Telesis supports both IGMP Layer 2 snooping and Layer 3
proxy routing. Depending on the size of the IP security network
and design, the systems can be congured for either a simple
bridging approach or a more comprehensive routing approach. In
most cases, routing is used at a video hub and aggregation point,
with bridging used at subtending ends.
Real-Time Streaming Protocol (RTSP)
In many instances, real-time IP video is merely streamed from
the source end to the host site rather than broadcast. Known
as Unicast, RTSP protocol is used as the streaming mechanism
Allied Telesis supports across its access platforms to deliver
Unicast along with Multicast video trafc. Unicast is primarily
used between cameras and servers as a point-to-point video
stream.
Allied Telesis solutions encompass the connectivity needs
required for a complete IP video sur veillance network, from
connecting cameras to backhauling video, to distribution via:
■ Power over Ethernet (PoE)
■ 10/100TX and BX
■ Optical-to-Electrical (O/E) media conversion
■ 100Mbps and Gigabit optical Ethernet
■ Gigabit and 10 Gigabit ber transport

IP Quality of Service
Allied Telesis places a high value on IP Quality of Service (QoS)
as a requisite for video as well as multiservice Triple Play (voice,
video and data). IP QoS is based on the use of VLANs, allowing
the user to set priorities (IEEE 802.1Q) as well as classications
of service (IEEE 802.1p). If there is more than one service in a
network (for example, IP video from a camera and trafc control
for a signal on the same pole), a VLAN can be assigned to each
service, each with its own classication and priority. This assures
contention does not affect per formance for one service over the
other. Allied Telesis also supports enhanced functionality such
as rate shaping, rate limiting and trafc policing through other IP
functions like DiffServ.
Low Latency
Allied Telesis uses chip and software designs to deliver extremely
low latency for video trafc, as real-time digital video quality
can suffer from latency or buffering. As one example, a number
of Allied Telesis Ethernet switches and iMAP carrier access
platforms support Ethernet Protection Switch Rings (EPSR) on
the ber uplink for redundancy in the transport network. Its
EPSR technology provides sub-50 millisecond failover switch
protection, delivering hitless protection for streaming video
should a ber cut or failure occur.
Layer 2 or Layer 3 Approach for IP Video
Whether to implement a more simple to congure Layer 2 IP
video network or create a Layer 3 routed video network is
somewhat dependent on the size of the network and application.
Single switch and small-to-medium IP video surveillance
installations typically require a less complex network using a
Layer 2 approach without the more complex multicast routing
capabilities.
Allied Telesis offers choices of Layer 2 and Layer 3 switches, or
conguring a Layer 3 switch as a Layer 2 device, as needed. Its
iMG gateway devices support both Layer 2 and 3 functions, as
does the iMAP carrier access platform. The products serve
as building blocks to create the right network at the right
location, with the scalability and exibility to deliver optimum
performance and economics.
Allied Telesis IP Video Surveillance
Partnerships
Allied Telesis has strategic partnerships with a number of major
IP camera and systems vendors, distributors, and integrators to
ensure customers benet from a total solution. Allied Telesis
works with partners to test and perform interoperability to
ensure the system meets performance expectations and
operates seamlessly. Allied Telesis and its solutions partners
understand customers want an integrated solution, without
having to arbitrate between multiple vendors. These
partnerships result in the intelligence and exper tise necessary
to provide a fully featured, high-performance IP networking
component as part of a complete IP surveillance solution.
Approaching IP video surveillance as a system through
partnerships reduces complexity, and therefore time to install,
test and tune video. It also assures end-to-end performance
requirements are met. Allied Telesis IP video par tnerships allow
customers the exibility to choose among industry-leading
equipment suppliers, VARs, and integrators offering the best t
to their par ticular application, requirements, and budget. Allied
Telesis welcomes customer requests to recommend or bring in a
partner, or propose a complete turnkey solution.
In larger installations that spread across a large footprint, or when
more than video may be transported in the network, a Layer
3 routing approach provides more control for services, as well
as allows for video to be placed into various subnets. Typically,
networks where multiple switches are used will benet from the
more robust performance and higher degree of management
that Layer 3 affords.

A facility may have IP cameras dispersed inside and outside the
structure, with a security monitoring center located on the
premises. This type of application is often found in a number of
common locations:
■ Ofce buildings
■ State, local, or federal facilities
■ R&D centers (secure)
■ Hotels, entertainment and hospitality venues
■ Banks and nancial ofces
A single 12-, 24- or 48-por t Ethernet Switch can be used,
depending on the number of IP cameras and clients that need
to be connected. In most cases, Layer 2 IP functionality is used,
including IGMP snooping, querying, and possibly ltering. Should
other data and/or voice also be shared on the network, Layer 3
VLAN routing is an option. The ideal application uses Power over
Ethernet (PoE) to distribute power from the switch to remote
cameras.
well as outdoor) using PoE. As required, the switch can
implement access security (IEEE 802.1x or MAC-based
authentication).
■ Servers can be networked directly via Gigabit por ts from the
switch to provide high-speed throughput for real-time high
denition video processing and storage. The 8000S/GS Series
switch provides support for both multicast trafc and unicast
feeds, and can also perform IGMP querying to intelligently
forward multicast packets to hosts that have requested it.
■ The 8000S/GS Series switch also sends IGMP queries to
maintain client membership of IGMP groups and deliver
trafc efciently. This avoids the problem of dropped leaves
creating unnecessary and unwanted multicast trafc that can
congest the network.
Alternative Solutions
To avoid any chance of a single point of failure, substituting the
8000S/GS Series switch with either the AT-9424T/POE or AT8624POE switches provides power-supply redundancy. Features
and functionality are the same, including models with varying
port densities, but they offer additional redundancy over the
8000S/GS Series.
There are occasional situations where only a few cameras and
a single host is needed, as in the case of a small retail store or
in those cases where distance requires the use of ber. In these
applications, Allied Telesis media converters and PoE injectors
provide a scalable and cost effective solution. Examples of these
products include the AT-6101G (PoE injector), AT-PC2002POE,
and AT-PC232/POE (ber-to-PoE media converters).
From a port capacity and bandwidth perspective, the ideal
switch choice is the AT-8000S/AT-8000GS family, due to its
outstanding economic value and features. Figure 1 shows a
simple IP security layout using a single 8000S Series switch with
PoE, 24- or 48-port available.
Additionally, Allied Telesis offers alternative solutions for IP
security cameras that do not suppor t PoE. Using a small,
economically attractive AT-6102G PoE splitter to directly
connect the camera allows power to be taken from the standard
PoE line and supply the camera with user-selectable voltages
between 5 and 12 V.

There are instances when, although the size of the IP security
network is not large, the nature of the security application
requires a higher level of redundancy as well as the ability to
deliver high availability. Some examples of the applications include
the following:
■ Military and defense facilities
■ Public utility facilities
■ Secure labs
■ Emergency service facilities
The Allied Telesis 9924 Series switch is the ideal solution based
on both performance and value for a high-availability application.
It is a fully featured Layer 3+ Ethernet switch, supporting
extensive QoS, IP security, routing, and of course IGMP
multicast functions. The 9924 Series switch offers hot swappable
redundant power supplies for reliability.

Because the 9924 Series does not support PoE, however, the
6100 Series PoE injectors can be used to bring power to cameras
using Ethernet cabling. The AT-PC232/POE media converters
could be used, as well, for cameras located farther from the
switch room if ber is used. Figure 2 shows an example of an
IP security network topology using the 9924 Series switch and
peripheral PoE equipment in a typical application.
Alternative Solution
The x600 Series Layer 3+ Ethernet switch with PoE can be
used to provide the necessary hardware redundancy with
PoE functionality. The x600 Series switch can also be stacked
to provide uplink and additional hardware redundancy using
Allied Telesis VCStack™ technology. This removes a single
point of failure by using two NICs bonded together into a Link
Aggregation Group (LAG) to the servers, with one connected to
each chassis in the stack.

Similar stacking options can be provided using Allied Telesis
SwitchBlade® x908 or x900 Series switches.

Many IP security situations encompass multiple cameras inside
and outside in multiple building clusters. In this distributed
architecture, a switch is needed within each building that
connects to a network switch in the central site where servers
and the main control center resides. Some typical applications for
a medium-sized application such as this include the following:
■ Medical/hospital facilities
■ Business/corporate facilities
■ Medium-sized retail shopping centers
■ Medium-sized educational institutions
■ MDUs (apartments, condominiums or hotels)
The distribution switches are generally Layer 2, with port
capacities scaled to the number of cameras and/or clients needed
to connect at each location. The network switch is generally
Layer 3, providing Gigabit ber connectivity to the distribution
switches, and Gigabit ber connections to the servers. For
resiliency, the network must offer link redundancy with failover
protection, allowing restoration of the connection within an
acceptable timeframe for continual operation.

Access
In a distributed environment like this, the network is divided into
core and access layers. The overall network topology between
the core and access switches is a ring with link failover capability
using Rapid Spanning Tree Protocol (RSTP).
The access switches connect to the IP cameras, and need to
provide PoE power as required. Other requirements for these
switches include IGMP snooping for intelligent forwarding of
multicast trafc, IGMP ltering in case additional control of IGMP
signaling is required, and RSTP to add link/node failure tolerance
to the network. The access switches are connected to each
other and the two core switches using a ring topology.
The core switches provide connectivity to servers and client PCs.
They receive the IP camera video feeds from the access switches
and forward this trafc to the servers. In turn, they receive
multicast trafc from the servers and deliver it to interested
clients. The core switches must provide enough bandwidth for
this high-trafc volume, IGMP snooping and querying capability,
as well as support RSTP.
www.alliedtelesis.com | 7
Page 8
Recommended switches for this solution include the following:
■ Access: AT-8000S/24POE or AT-8000S/48POE
■ Core: Stacked AT-9924 or SwitchBlade® x908
This solution offers a good level of reliability, as the core switches
are redundant. RSTP recalculates the network topology to
re-establish connectivity with all the nodes in the network.
Depending on the location of the break, trafc ow can be
restored in under a second using the RSTP rapid-transition
mechanism. At most, RSTP will restore connectivity in 5-15
seconds, as all the links are point-to-point. In this solution, it
is not only necessary to restore connectivity, but also to reestablish correct multicast forwarding through the switches.
This requires the IGMP query source to induce a refresh of the
switches’ IGMP forwarding entries. Using Allied Telesis IGMP
query solicitation (SwitchBlade x908, x900 and 9924 Series), the
multicast path can be re-established within a second or two after
RSTP re-convergence. This feature allows the switch to force
an immediate general query when an RSTP topology change is
detected.
Access node failure will result in all the cameras connected to
that node being unavailable. As described above, connectivity of
the rest of the cameras to the servers is quickly restored. Core
switch failure does not result in lost server connectivity, as link
aggregation via teamed NICs provides connection to both core
switches. If client devices are not employing NIC teaming, then
clients connected to the failed core switch will be unavailable.
After RSTP re-convergence and IGMP signaling update, all the
camera feeds will be available.
Alternative Products and Accessories
Other Allied Telesis switches available to build a network with
similar features include the following:
■ Core switches: SwitchBlade x908, x900 and x600 Series
■ Access switches: AT-9424T/POE and AT-8624POE
In a medium-size network, legacy switches can be reused—
even if they do not have PoE suppor t—with the option of an
inexpensive Allied Telesis PoE injector (AT-6101G).
Media converters with PoE can also be used for connecting IP
cameras over a long-reach ber strand.

This solution is similar to the previous one, with the exception
that no service downtime is allowed. As real-time video is
sensitive to latency and buffering, the goal in a situation where
high availability is required is to limit failover protection (switch
protection) to a range of 50 milliseconds. High availability is
typically required for several types of applications:
■ Military and defense
■ Secure facilities (for example, prisons)
■ Airports and other facilities where terrorism concerns exist
■ Secure labs and research facilities
The Allied Telesis virtual chassis stacking solution (VCStack),
together with link aggregation, can be used when high availability
is required. This approach allows a simpler network topology and
conguration as well as more efcient use of bandwidth.

aggregated links, one to each member of the stack. The use
of link aggregation is made possible because the two core
switches are a single virtual chassis. Such a topology creates
a loop-free network with link and core switch redundancy.
Application servers (and optionally clients) can be equipped with
two or more NICs and use NIC bonding to provide resilient
connections to the core. A clear benet of this conguration
is that no single point of failure exists in the critical part of the
network and there is no ser vice downtime in case of link failure.
Alternative Products and Accessories
Allied Telesis alternative products supporting VCStack include the
SwitchBlade x908 and x600 Series. In a medium-size network,
legacy switches can be reused even if they do not have PoE
support with the option of a PoE injector (AT-6101G).
Two x900 switches form the “virtual” network core. Each
access switch is connected to the core switches with two

In a large campus network, or metro-area network, the video
surveillance system is typically overlaid on an infrastructure that
has been designed to carry multiple applications and services.
Such a network, supporting a signicant number of end-users,
needs to be very reliable, manageable, and scalable. Such
applications are often found in several facilities:
10 | IP Security and Surveillance Solutions
■ City or municipal street and public surveillance networks
■ City or municipal trafc monitoring networks
■ Transportation, transit line networks
■ Large education campuses (college, university)
■ Large business parks
■ Large retail malls
■ Military bases
Page 11
There are often other data connections, even other video such
as conferencing, and possibly IP voice, within the same network.
These requirements are best met by a network design in which
different services are partitioned into separate VLANs, and
transported over resilient rings protected by an extremely fast
failover mechanism.
The Allied Telesis fast-failover ring protection solution is the
Ethernet Protected Switching Ring (EPSR). This is an extremely
reliable, high-performance ring protection protocol that can
restore connectivity within 50ms of a link failure being detected.
Services such as video surveillance can each be provisioned with
one or more VLANs running over the EPSR rings, with data on
Layer 2 or Layer 3 switched between the rings and the centralsite facility.
A reliable, scalable design is achieved by subtending multiple
rings off multiple SwitchBlade® x908s with VCStack™ providing
the gateway between the rings and central site. For ease of
management, control, and troubleshooting, a different videosurveillance VLAN runs in each ring, and the SwitchBlade x908
VCStack Layer 3 switches the video streams from the rings to
the server and client devices at the central site.
This network design is very scalable, potentially providing
extremely reliable network services to thousands of end users,
and hundreds of surveillance cameras. When multiple services
share the same network infrastructure, it is necessary to ensure
each experiences the Quality of Service expected, ensuring
timely delivery of trafc and access to applications when required.
Bandwidth usage must be controlled, so no one service can
starve the others of bandwidth. Moreover, for loss and jittersensitive applications like video, it is extremely impor tant to be
able to deliver the data streams in a smooth, lossless fashion.
The Allied Telesis SwitchBlade x908 and x900 Series switches
are extremely feature-rich Quality of Service offerings that can
manage the characteristics of over 1,000 separate data streams
simultaneously, thereby making them ideal for the provisioning of
shared-service networks involving real-time applications.
A link failure in any ring results in EPSR recovering in as few
as 50 milliseconds, usually undetected even by users of realtime services like video or voice. A failure of a unit within the
SwitchBlade x908 VCStack will automatically recover with
minimal disruption.

It is common to mount IP security cameras on poles, trafc
lights, or even on buildings outdoors. Additionally, there are
numerous cameras dispersed over a wide area. It becomes
economically impractical to put a switch at each location, and it
is further compounded by the need to have electronics capable
of withstanding the rigors of non-environmentally controlled
locations. Although NEMA-rated cabinets are often present to
provide power, they do not provide adequate protection against
extreme heat or cold.

Reference Solution
Allied Telesis offers a carrier-class ber ONT, the iMG 7x6MOD
Series, designed for FTTH and use on residential exteriors. The
iMG 7x6MOD is an extended-temperature product in a sealed
enclosure with a ber and electronics tray designed to NEBS
level 3 environmental specications.
12 | IP Security and Surveillance Solutions
Page 13
Using the iMG 7x6MOD, ber is run from a centralized switch
to the pole, trafc light, or similar outdoor location, allowing up
to a 20-kilometer distance between a switch and the IP security
camera. Each iMG 7x6MOD has six 10/100TX Ethernet ports,
allowing the ability to connect up to six cameras in a location —
on the same pole or even adjacent poles, or buildings within the
distance that Cat 5e Ethernet cable permits. The iMG 7x6MOD
uses one 100Mbps active Ethernet point-to-point single-mode
ber connection between it and the switch.
Since most IP cameras in trafc or street surveillance applications
have access to and use local power, PoE becomes much less of
a requirement. The iMG 7x6MOD can be mounted inside a
NEMA cabinet at the base of a pole and powered from there,
or on the side of a building and AC-powered from the building.
Figure 6 shows the use of an iMG 7x6MOD extending from a
central ber congured switch for outdoor applications.
Alternative Solution
The alternative solution is the use of an FS232x Series media
converter to convert from Ethernet over ber to copper at
the camera location. It is also applicable when multi-mode
ber is used, since the iMG 7x6MOD is strictly a single-mode
ber device. As a simple optical-to-electrical media converter,
this allows a single IP camera to connect to a single ber from
the switch (options of single-mode or multi-mode type ber
supported). The FS232x Series media converters provide an
unmanaged solution. However, this is generally not an issue at
remote camera sites. Media converters, though, are not designed
to the same hardened temperature specication of the iMG
7x6MOD. They are best suited for use in NEMA-rated cabinets,
which afford a maximum degree of protection against outside
temperature, moisture, and humidity.
