How to Conduct a Security Site Survey Steve Surfaro Group Manager Enterprise Systems www.panasonic.com/security [email protected] Agenda • Where does the Security Site Survey sit in the scheme of a Physical Security Program? • Advantages of the Assessment Process • Identify the System Types to match and minimize the Risk Types • Conduct the Site Survey Pre-Assessment Phase • What are you going to Assess? • Protection this key information with procedures • Identify and Rank Critical Assets Assessment • • • • • • • • • • Analyze Network Architecture Assess Threat Environment Test and try to defeat the System Assess Physical Security The Conduct Physical Asset Analysis Assess Operations Security Examine Policies and Procedures Conduct Impact Analysis Assess Infrastructure Interdependencies Conduct Risk Characterization “Site Survey” Post-Assessment • • • Prioritize Recommendations Develop Action Plan Capture Lessons Learned and Best Practices • Deploy Security System • Conduct Training Advantages of Conducting Assessments and Surveys • • • • Increase awareness, not necessarily paranoia Establish a baseline Identify vulnerabilities and develop responses What key assets drive the risk management process • Promote action to minimize risk • Kick-off your Physical Security Program Video Surveillance System Survey – Functional Aspects • Classify Video System by type: – – – – – Video Surveillance (Monitoring Function) Forensic (Recording Function) Video Analytics Perimeter Security Access Control • Classify Camera by Function – – – – Monitor basic activity (subject is 5% of vertical) Detection (10%) Recognition (Human, Animal or Vehicle) (50%) Identification (120%) Subject Size & Camera Function Monitor Not less than 5% Vertical Detect Not less than 10% Vertical Recognition Not less than 50% Vertical Identification Not less than 120% Vertical *courtesy Isle of Man Constabulary; CCTV Systems within Licensed Premises Using Lens Estimator to Size Lens • • • • Enter Scene Height, Width and Distance for Each Camera As an alternate, note actual viewing angle on scaled diagram Determine Object Height on Monitor to Match Functional Requirement Determine Focal Length Sample Equipment for Video Site Survey • • • • • • • • Laptop Computer Fixed “Box” Type IP Camera Long CAT6 Stranded Crossover Cable Assortment of Varifocal Lenses Tripod/Ball Head for Camera Light Meter with Gray Card Rotakin Test Target LED Infrared Illuminator/Power Supply Video Surveillance System Survey – Physical Aspects • Viewing Angle • Environment – – – – – – – – Lighting type, level Reflectance/Emissivity Obstructions Temperature Humidity Corrosives Water Vandalism • Mounting Conditions – Cabling Entry Requirements – Accessibility • “Special” Objects / Scenes (some examples) – Vehicles – License Plates – Shoreline/Border – Transit Platforms Camera Functions • In Critical Locations, Back up PTZ Cameras with a Fixed Camera • Consider Activation Methods for PTZ Camera Preset Acquisition in Survey • Use widest usable field of view for fixed camera Site Survey Cycle • Enter Site Survey Data (Rough Sketches, Location Notes) • Normalize Devices by Camera Types • Transfer to Floor Plans • Verify samples with actual site Site Survey Verify at Site Verify Data to Product Types Create Floor Plans Use a Standard Site Survey Form Location Site Survey Sheet Company Name Address _____________________ _____________________ _____________________ _____________________ Building # Entrance # Door # Area Drawing Reference Symbol Key C Fixed Camera C PTZ Camera PTZ Dome Camera Recorder 2U Fixed Monitor • Location Information • Symbol Key References Camera Equipment Group Categories • Building Plan Area • Device/Mounting Details Area Wireless and Wired “Combination” Application Video System Design – Best Practices • Make sure users have the live and recorded image quality they need • Maintain most favorable criteria for your project – – Lowest Reasonable Cost for System Increase the number of ways you can access your video information – Spend as much as you can afford to strengthen and secure your network • Do not have one device service too many users or perform many functions – Improve your System Survivability • Model all network-based systems prior to specification phase Conclusions • The Assessment and Survey Process increases awareness • Think “like a thief” and ways to defeat the system • Expect wider ranging environmental conditions (light, etc.) than seen at survey • If using wireless technologies, you must conduct a separate RF Survey • Limit the Camera Usage to its primary function • Use additional Cameras for simultaneous functions in critical areas
