One of the applications rolled out as standard when people are trying to promote the use of faster broadband is Closed Circuit TV. I’ve always treated this with some contempt as a poor contribution by some unimaginative marketeer somewhere desperate to think of reasons why someone should upgrade their connection.
In the interests of pursuing the theme of bandwidth bandits I was however prompted to look into CCTV as a subject. I am amazed the progress in this space.
Timico uses a product called X-Protect. Cameras plug directly into the LAN and are powered by Power over Ethernet. The product supports a number of codecs including H264 and MPEG-4 and you can select the quality of your stream based on how much bandwidth you have.
As an ISP with a high bandwidth Gigabit fibre based WAN Timico has plenty of bandwidth and our cameras stream at an aggregated 10Mbps to the recording server. Timico IT staff can view these streams from anywhere in the network, including from home and including on the move with their PDAs. The bandwidth used for viewing from outside the network does not of course have to be the same as on the LAN/WAN.
What this does show though is an application that is promoting high bandwidth usage. Manufacturer Milestone Systems states a recording capacity of 960GB per day per server. A quick back of a beer mat calculation suggests this would need a total of around 90Mbps streaming to support this capacity.
The only way is up for bandwidth usage.
