Snappy Surveillance
Snappy Surveillance security has moved to the forefront globally as a strategic
tool in protecting corporate assets against terrorism, crime prevention, and public
safety. At the same time, video surveillance usage is increasing as a tool
remotely from an operations center. To support the IP video network and enable remote
camera control and operation, a high-speed IP/Ethernet net work is required with
it s design and functionality tailored to IP video applications. for traffic monitoring
and local government security. The days of grainy and blurry analog Closed Circuit Television (CCTV) systems have been replaced 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 fixed or adjustable cameras suited for many applications.
They serve the needs of military army, government, utilities, corporate, medical,
retail, hospitality , transportation, and education and more. To serve the wide
variet of needs and applications, whether indoors or out, a reliable high-speed
IP net work is needed to connect cameras, servers, and the operations center where
monitoring occurs, whether inside a building or top a roof or traffic 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 specific requirement. A “one solution fits all” approach lacks the robustness
and economic efficiency to solve t he range of applications required of IP video
surveillance. by advanced digital IP cameras and systems producing
high- resolution, high-definition, real-t ime video. Along with that new technology,
the high-speed IP net working infrastructure enabling it is critical.
Allied Telesis places a high value on IP Quality of Service (QoS) as a requisi
te for video as well as multiservice Triple Play (voice, video and data). configuring
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 product
s serve as building blocks to create the right network at the right location, with
the scalability and flexibility to deliver optimum performance and economics.network
(for example, IP video from a camera and traffic control)
Low Latency
Allied Telesis uses chip and software designs to deliver extremely low latency for
video traffic, 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 fiber uplink
for redundancy in the transport network. It's Ethernet Protection Switch Rings (EPSR)
technology provides sub-50 millisecond failover switch protection, delivering hitless
protection for streaming video should a fiber cut or failure occur
Alternative Solutions
To avoid any chance of a single point of failure, substituting the 800 0S/GS Series
switch with eit her the AT-9424T/POE or AT- 8624POE switches provides power-supply
redundancy. Features and functionality are the same, including models w ith varying
port densities, but they offer additional redundancy over the 800 0S/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
t he use of fiber. 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 (fiber-to-PoE
media converters).Additionally, Allied Telesis offers alternative solutions for
IP security cameras that do not support PoE. Using a small, economically
at tractive AT-6102G PoE split ter 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.
