• Introduction• Objectives• Video Surveillance System (VSS) Standard• Conclusion
INTRODUCTION
3
• A new Video Surveillance System (VSS) Standard for Buildings was drafted in line with the improvement in technology.
• VSS deployment to support and enhance the overall management of a building’s security.
• Most effective when deployed with other security measures (e.g. access control, alarm systems).
OBJECTIVES
4
Video Surveillance System (VSS) Standards• Provides for a uniform and consistent approach for
the technical specifications, installation, operation and performance of VSS across buildings in Singapore.
• Provides guidelines to the industry in the deployment of VSS
• Helps in security management and assist in post incident investigations/reviews.
CAMERA
5
• Resolution of HD 1080p: 1920 x 1080 pixels or its equivalent– Widescreen: cover wider areas, lesser cameras will
be required
SD ResolutionHD Resolution
CAMERA
6
• Resolution of HD 1080p: 1920 x 1080 pixels or its equivalent– Better Resolution Subject identification Illegal activities
detection Allows for the
addition of video analytics subsystem
SD Resolution HD Resolution
CAMERA
7
• Network IP-based Cameras, recommended to be compliance to Open Network Video Interface Forum (ONVIF) standards
• Minimum height of 2m from floor level
• Vandal-resistant and Tamper-proof enclosure
• Good colour reproduction for easy identification
• Fixed Cameras are deployed to meet coverage requirement; Pan-Tilt-Zoom (PTZ) Cameras can be used as a supplement to fixed cameras
• Lift lobbies• Staircase landings• Ingress/Egress for
Human/Vehicle For identification of vehicle /
person of interest entering / exiting from the building
COVERAGE REQUIREMENTS
8
• Main entrance lobby• Registration counter
COVERAGE REQUIREMENTS
9
• Public Access Areas– Street areas within building’s boundaries– Entrances / Exits to MRT stations
COVERAGE DEFINITION – HD1080 RESOLUTION

Detect / Observe – 10% Recognize – 20%
10% of Panel Height
20% of Panel Height
Identify – 45%
45% of Panel Height
RECORDING
11
• Open-format CODEC and video container format
• Period of Archival: 28 days + 10% buffer• Basic Metadata: GPS time and date to be watermarked
on recorded images• Image quality of HD1080p: 1920x1080
– Good quality images for post incident investigations– Clear images allow for speedier identification of the subject
which will lead to faster apprehension of the perpetrator • Recording and storage facility:
– Preventive measures against unauthorised removal/ viewing of recordings
– Sited in the inner perimeter of the building
LIGHTING
12
• Ensure that the artificial/natural lighting does not blind the camera view.
• Lighting should be continuous and sufficient to support VSS coverage.
• Light source is recommended to be a minimum of 2m from the camera.
• Preferred position for the lightis above the camera.
CAMERA SYSTEM
13
• Reserve viewing terminal– For Emergency Response Agencies
• System Integrator (SI) / Vendor to provide Software Development Kit (SDK) for commands including Select Camera, View, Extract, PTZ and Playback
• VSS designed and installed with a minimum f 20% spare capacity for future expansion
• Signage– Strategically located to inform the public that the
VSS is continuously monitored and recorded– Building owners may opt for Digital TV instead
ALARMS & ANALYTICS
14
• Alarms may be installed to inform the users of potential issues from the camera system:– Video loss alarm– Tamper alarm
• Video Analytics may be deployed to help the CCTV operators in picking up suspicious activities– Loitering– Unattended bag
CONCLUSION
15
Video Surveillance System (VSS) Standard for Buildings
A set of VSS Standard to provide guidelines to the security industry in the deployment of VSS to enhance the building’s overall security.
