DESCRIPTION
TRANSCRIPT
CCTV Requirements Gathering
• The business requirements will form the basis of future projects and will determine the eventual scope.
• If a ‘need’ is not raised as a requirement, the project will not know that the system must perform an action- therefore it will not be included within the scope of the project or included within the end solution.
• The requirements will be base-lined at the end of the Initiate Phase. Any requirements submitted after this date will not be accepted without a change request and associated funding (where applicable).
• The identified business stakeholders are responsible for ensuring that all requirements are raised during the Initiate Requirements gathering process.
The Importance of Requirement Gathering
• Review each area of CCTV functionality.
• Prepare a set of draft CCTV BUSINESS requirements for each of the functional areas.
• Agree a priority for each draft requirement.
• Agree next steps, actions and areas for further investigation.
Workshop Objectives
Defining the Problem
• What types of threats are experienced?
• What is the level of threat experienced?
• Where are the threats experienced?
• What are the current security issues?
• What other tactics are used other than CCTV to tackle the threat?
• How often do threats occur?
• What is the impact of the threats?
• What is the impact of not tackling the threat?
• How is success measured by the security teams?
Defining the Nature of the Threat- Discussion
Recognise•Figure occupies at least 50% of the screen height.•Observers should be able to say with certainty whether or not an individual shown is the same as someone they have seen before.
Identify•Figure occupies at least 100% of the screen height.•Picture quality and detail should be sufficient to enable the identity of an individual to be established beyond reasonable doubt.
Observe•Figure occupies at least 25-30% of the screen height. •The characteristic details of the individual can be seen whilst the view remains wide enough to allow some activity surrounding the incident to be monitored.
• Which of the categories best reflects the type of activity being observed?
Observation Categories
Monitor & Control•Figure occupies at least 5% of the screen height.•The observer should be able to monitor the number, direction and speed of people movement across wide area.
Detect•Figure occupies at least 10% of the available screen height.•The observer should be able to search the display screens and ascertain with a high degree of certainty whether or not a person is present.
• Which of the categories best reflects the type of activity being observed?
Observation Categories
Operational Practice
