Pictures Speak Louder Than Words

Video surveillance is an integral part of modern security systems, found in all kinds of premises ranging from airports to shopping malls, and corporate buildings to train stations. It provides a great deterrent to malicious behavior and is an excellent tool in solving the mystery of past misdemeanors.

In today's digital world, security has also embraced the advantages of instant access to images stored and retrieved on computers. Allied Telesis offers a diverse portfolio of products, and a suite of features, that enhance the ability to securely and reliably transport security video footage across an IP network.

IP surveillance systems generally involve a number of devices—IP video cameras, servers, and clients—and involve multicast technology to deliver video streams to every intended recipient:

  • Smaller installations are based on Layer 2 switching technology, while larger scenarios include options for a Layer 3-routed environment.
  • The pure Layer 2 approach is preferable in small to medium installations, due to its simplified network configuration and maintenance. It does not require a complex multicast architecture involving multicast routing protocols.
  • In larger systems, it is likely that the video data will be transported in an environment divided into separate IP subnets, in order to enable scalability, and provide a network that is both robust and easily managed.
