IP Video Surveillance
Video Surveillance is an integral part of modern security systems, found in premises ranging from airports to shopping malls, corporate buildings to train stations. It proves a great deterrent to malicious behavior and an excellent tool in solving the mystery of past misdemeanors.
In this digital world, security has also embraced the advantages of instant access to images stored and retrieved on computers. fortune it offers a diverse portfolio of products, and a suite of features, that can enhance the ability to securely and reliably transport security video footage across an IP network. IPTV surveillance systems generally involve a number of devices — IP cameras, servers, and clients — and involve multicast technology to deliver video streams to every intended recipient.
Following are a variety of reference designs for fortune it -based network solutions that support IP video surveillance. The smaller installations are based on Layer 2 switching technology, while the larger scenarios include options for a Layer 3 routed environment.
The pure Layer 2 approach is preferable in small to medium installations, due to simplified network configuration and maintenance. It does not require a complex multicast architecture involving multicast routing protocols. However 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.
Small Sized Network
In a Point of Sale (POS) and security camera installation with a limited number of cameras, a single or small group of Allied Telesis WebSmart Power over Ethernet (PoE) switches is an ideal solution because of its simplified network configuration and maintenance requirements.
Medium Sized Network
In medium-sized IP Surveillance networks, or a LAN, the video surveillance system is typically distributed with one or more switches in each location connected together.
Large Sized Network
In large IP Surveillance networks, or a 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 significant number of end-users, needs to be very reliable, manageable and scalable. These requirements are best met by a network design in which different services are partitioned into separate VLANs and transported over resilient rings that are protected by an extremely fast failover mechanism.
