Mesh networks are self-healing: the network can still operate even when a node breaks down or a connection goes bad. As a result, a very reliable network is formed, with connections being reconfigured around broken or blocked paths by re-routing data from node to node until the destination is reached.
The reliability of a wireless mesh network can be easily upgraded by simply adding additional ‘redundant’ nodes to the network. A large number of strategically distributed redundant nodes allow a mesh network to recover from multiple points of failure – ideal for deployment within hostile environments or military applications.
IES Wireless security solutions operate over well-established 802.11 b/g standards and make use of AES encryption to secure video and data transmission. These networks are fully compatible with the IP protocol and with any IP-based video-surveillance product. This meaning existing IP-based surveillance equipment like IP cameras and video-servers can often be integrated within a new WLAN solution, and the network architecture places no restriction on selection of network enabled technologies.
IES wireless mesh networks are self-optimising for routing of either MPEG4 or M-JPEG video packets, automatically detecting and adjusting performance for the type of video packets and transport protocol in use. Video packets are prioritised over data packets in order to minimise disruption to surveillance channels, and multicast support is also available to reduce bandwidth requirements for specific applications.
