Got an excellent article from cabling manufacturerSiemon about \'Structured cabling and how it can support Video Applications\'. Interested? See download sample. entire (translated!) articel can be obtained by mail

1. Cabling a better view
Moving analogue applications to an IP network offers big advantages, bringing new
and valuable possibilities. Graeme Stoker of Siemon considers the challenge.
As volumes and types of IP network traffic change, so does expectation. With traditional
data, users had no care about such things as response times, as long as there was one.
But the addition of IP versions of familiar services, for example telephony, comes with
expectations, and these will only be fulfilled with careful planning of the physical
infrastructure, based on understanding…
Traditional IP data is very tolerant and time can be afforded to ensure accuracy and
completeness before rendering to a user. Building management systems such as door
access are even more tolerant, but video is real time and when combined with voice, even
small amounts of signal delay (latency), jitter, or noise can be catastrophic. Much is done
above the physical layer to deal with these challenges, for example traffic shaping and
Quality of Service (QoS) schemes, but the same effort is rarely made concerning the
cabling infrastructure. Analogue devices, such as surveillance cameras, previously
connected by generic coaxial cabling, are moving onto the network and other IP
applications such as IP data recorders, visual recognition, building access control and IP
based television services (IPTV) are following.
