CLOSED CIRCUIT TELEVISION PRACTICAL CONSIDERATIONS FOR SYSTEM IMPLEMENTATION PHILLIP BOYD

SYSTEM DEFINITION AND IMPLEMENTATION OVERVIEW Business Requirement Risk Assessment Operational Concept Requirements Analysis Functional Technical Support Budget: what resources are available? Through Life Support: specialist skills, recurrent costs Constraints: legal, technical, perception, commercial

SYSTEM DESIGN PHILOSOPHY CCTV is one part of the solution, and not a panacea for public safety and security Improve public perception of safety Deter and displace anti-social behaviour & crime Provide usable, high quality evidence Integrated with the environment Consider user/corporate/statutory requirements Understand constraints, mitigate or design out Ensure support is straightforward

TYPICAL CONFIGURATION

CAMERA SELECTION Select camera/housing based upon: – Areas requiring coverage, level of detail and resolution – Distance from camera to target area, and streetscape – Environmental conditions (e.g. hot/humid; cold/icy) – Vandalism risk – appraise threat, choose solution – Whether operational use by police or council required – Planned system life, durability and upgradability

NETWORK SELECTION Select CCTV network based upon: – Need for centralised monitoring/recording or stand-alone cameras – Existing network infrastructure (optical fibre/copper/wireless) – Ownership of assets (lighting poles, power poles) – Distance between cameras and recording/ monitoring site – Potential system growth or reorientation

SYSTEM POWER Powering can be problematic – Civil/Electrical works and pole leasing costs – Trenching/traffic management/MoUs/RoW – Is mains readily available? Is solar an option? – Low power CCTV systems, standby modes, movement activated in remote locations/depots

VIDEO STORAGE Video archiving is vital – Evidence preservation – Local to camera or centrally – Recording period and video quality – Protocols for access and release

ENVIRONMENTAL FACTORS Trees, sculptures, temporary structures will affect coverage – landscaping is an important factor Light doesn’t bend – much – so the camera must be able to view the target High variance in illumination (light/shade) is not desirable (lighting uniformity defined in AS) Architectural aesthetics may not favour even discreet CCTV positioning Consider the effect of new or altered buildings

RUNNING THE SYSTEM Maintenance strategy to suit environment (inspection, cleaning, servicing if required) Range of fault detection options (tamper, lens obscuration, incorrect camera position) Consider bundled maintenance agreement with well defined performance criteria
