Video - Essential for Today’s Subway Systems
November 2011
1
Why is Video “Essential”?
 Around the world, subways are vulnerable to a variety of
threats
 Safety
 Security
 Evidence
2
Safety
 In Korea, an arsonist starts a fire
on a train killing more than 200
people…
3
Security
 Aggravated robberies are up
40% on Metro subway in Paris –
smartphones are the favorite
target
4
Evidence
 In a New York subway station, a
woman strikes an officer…
5
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)
6
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

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

 There are two operating car for up-bound and down-bound

Each operating car has indoor MESH node (6102) with 18GHz frequency
upconverter

IP Cameras are inside passenger train and this video stream is delivered into
MESH node through inside cabling
