Functional specification for the CUSSMOS System

City University has asked us to create a new security system, the CUSSMOS. The current system is subject to too many material losses in the buildings, “theft”, mainly committed by intruders. You want a security systems that allows you to know who is in the building and where at any moment. It also has to be able to detect intruders. You require the system to be simple to use, provide maximum security but with causing the less inconvenience possible.

It is a complicated system to design as it has to cover every single area of the buildings at all time but it has to be discrete, not too “eye-catching”.

This system as to detect movement in the buildings and have the ability to identify the person that is moving. It also has to detect people who do not carry a CUSSCard and alert security straight away to be able to intercept the individual. The main Computer (CUSSBASE) has to keep record of every cardholder’s identity. The CUSSENSEs have to be powerful enough to cover every possible area.

For the moment, City University operates with a swipe-card and manual card check system. People who enter the buildings are asked to show their City University ID to a member of staff.

To enter certain areas such as the computer labs, people have to swipe their card, and if their ID is valid, the door will unlock. The problem is that this system is too hard to control. Every single person that enters the building cannot be checked.
