    • Megapixel Surveillance in Real World, Fantasy or Reality?
      Chandler Zhang
      International Business Representative
    • Table of Content
      Megapixel Technology: Fantasy or Reality?
      Case Study: HD Surveillance System
      HIKVISION overview
    • HD Surveillance: Fantasy or Reality?
      Current Challenges:
      The cost for large scale surveillance system would increase dramatically if using megapixel technology (compared to regular surveillance systems)
      The networking infrastructure between different systems is very complicated given the amount of data flow, latency, etc.
      Difficult to encode and decode in real-time with large scale megapixel technology deployment
      Difficult to expand the system
      High management and maintenance cost
      Lack of know-how
    • Solutions?
      Current Requirement by End-users
      Integrated networking video surveillance system
      Simplified large-scale video surveillance system
      Real-time video surveillance system
      Shows super high clarity and details
      Centralized data storage and management
      Video analytics
      Open protocol and interface
    • Transition of Video Surveillance
      Video Analytics
      • Analog Camera + VCR
      • Analog Camera+ DVR
      • Analog Camera + Video Server + Storage
      • IP Camera + DVR/NVR
      • HD IP Camera + Storage
    • Current Status of Video Surveillance
      The mainstream of the industry is still using CIF and 4CIF resolution
      The current video surveillance system is mainly used for event recording. Details of the event, however, are not “detailed” enough yet.
      The bottleneck was in technical development and market adoption.
      Who is this guy?
      Is it $80K or $90K?
    • Advantage of HD Surveillance
      More details!
    • Requirement: Need to see both the license plate and driver’s face
      HD Camera
      Analog Camera
    • Advantage of HD Surveillance
      Wider coverage per camera = less cameras on-site
      HD Camera
      Regular Camera
    • Everything HD
      An Ideal HD Surveillance System
      Video Input: With HD IP camera, HD digital camera, or HD encoder
      Management Platform: Supports centralized/distributed HD video stream and management command
      Storage: Supports storage and retrieval of HD video data
      Decoding and Video Output: Directly process HD video data for output
      Video Display: HD display
      Other Application: Such as video analytics – higher resolution brings higher accuracy for video analytics
      HD Transmission: Supports HD video transmission. Transmit uncompressed video stream can also be considered in order to lower the latency.
    • Case Study: HD Surveillance System
      Shanghai Pudong, where World Expo 2010 are being held in.
      Total visitor :6,528,460,000(up to Jun. 9)
      Establish a comprehensive high-definition surveillance system in order to monitor the Expo closely and discover criminal activities in real-time.
    • System Requirement
      Wide Coverage
      Covering 42 police stations, 6 sub-monitoring stations, and 1 central monitoring station in Pudong, Shanghai.
      Over 12,000 surveillance spots.
      Using the latest surveillance technology, products and infrastructure to achieve high security requirement.
      Need to be able to extend for the future requirement.
      Easy to Manage
      All the sub systems need to be centrally managed.
    • Why HD?
      Wider Coverage
      In order to have a wider coverage, you need to have hundreds or thousands of VGA cameras in place.
      The information in one single HD camera equals to several VGA cameras.
    • Why HD?
      Apart from the increased clarity of the image, HD camera also has ePTZ function for user to track or zoom in the targeted object in order to get the details.
      Provide details for license plate, driver and passenger in vehicles, etc.
    • System Infrastructure
    • Data Flow
    • Data Flow
      Real-time Tracking
    • Success in Large Scale Deployment
      Has money
      Has clear ideas about what they want and what they like to achieve
      Think big and long
