  1. CLOSED CIRCUIT TELEVISION PRACTICAL CONSIDERATIONS FOR SYSTEM IMPLEMENTATION PHILLIP BOYD

  2. 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

  3. 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

  4. TYPICAL CONFIGURATION

  5. 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

  6. 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

  7. 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

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

  9. 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

  10. 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
