When the University of Oxford's security department decided that they need an overhaul of the security system that was in place on the campuses and at the building around the location they new they needed the best technology to ensure safety to their students and staff. They chose to have networked CCTV using multiplexers that were supplied by Dedicated Micros.
To make the complete networked CCTV system they were advised to use four of our BX2 multiplexers which would support the sixty cameras that had been augmented to digital quality images to further enhance the quality of the pictures that were coming through to the main control centre, as the University actually holds some of the most historical buildings in the country, and the demand on the original analogue cctv system which had thirty cameras had risen to the sixty that they need and a coextensive expansion in video cassette recorders and place to store analogue tape. The University was trying to assimilate its way of looking at security and monitor the networked CCTV system centrally from a secure location, but also be able to monitor from a location to be used as back up harmoniously without any loss of quality from the mpeg4 streaming images. With the old analogue systems this could involve digging up most of the grounds in and around the University and filling the holes with lots of fibre optic cables, instead we decided the best way to go about this was to fit a virtual private network, so that access can be done from both the primary and secondary location very securely. This was chose as the best security solution available as it will give the facility of seeing all of the images from any camera from any part of the University that is networked. By utilising Dedicated Micros newtrok viewing software, the whole of the networked system will let any of the staff that are involved with security and have the access codes for the local personal computers to view live images, or look at archived images from any computer on the network. As the University is divided up over a large area of Oxford there are areas where the CCTV comes in to it's own as we made the images bet relayed directly to the Thames Valley Police, so if there were areas that there were no security staff at then the Police could get a quicker response to the area. The system is capable of being expanded so that individual colleges can have recording units allowing them to control their own systems on site, but giving access to the security services control room for continuous monitoring. The security firm at Oxford needed a networked system that had a high specification but also something that was easy to use and meant that the staff didn't need totally re-training to understand the in's and out's of a newly developed system and that is why the BX2 was the perfect solution. There is a massive amount of storage available with this system in fact it is somewhere in the area of around one point two tera bytes, and using around two frames per second this means there will be around four months of information stored locally.
