1 Video - Essential for Today’s Subway Systems November 2011

2 Why is Video “Essential”?  Around the world, subways are vulnerable to a variety of threats  Safety  Security  Evidence

3 Safety  In Korea, an arsonist starts a fire on a train killing more than 200 people…

4 Security  Aggravated robberies are up 40% on Metro subway in Paris – smartphones are the favorite target

5 Evidence  In a New York subway station, a woman strikes an officer…

6 Challenges for Subway Video Surveillance  Support real-time streaming of high quality video to central location for recording  Support fixed cameras (stations, parking lots, tunnels)  Support mobile cameras (trains, officers)

7 Considerations in Designing a Network for Video  Determine where cameras are to be mounted Fixed cameras Mobile cameras  Assess if there is high-bandwidth connectivity for camera locations Utilize existing network cable were available/cost effective and adequate bandwidth is available  Identify locations where high-bandwidth cable is unavailable Use high-bandwidth wireless network  If deploying mobile cameras capable of streaming, requires high-bandwidth mobile wireless network

8 Network Requirements for Video  High reliability  Flexible scalability  Strong security  Seamless mobility at +60mph  Single network for concurrent video and data  Scalable  Cost effective to deploy and maintain

9 Case Study - Seoul Subway Technology  Real-time high resolution video monitoring  Mobil wireless connectivity  30 fps video at 60 mph with zero packet loss Benefits  Early accident detection such as fire etc.  Increase passenger safety and prevent thefts  Allow operator to preview the station before entering

10 Internet Gateway Internet Security Monitors  Main Application - Video Surveillance with mobility, 18GHz frequency upconverter  Project timeline - Pilot : Apr Deployment : Jun - Oct.2009  Project details (indoor MESH) x 1000 for station & mobility (Each line has stations) (indoor MESH) x 100 for NGI Gateway Server  Train speed : MAX 80Km/H Fiber Optic Cable 18GHz Project Details Network in Subway
