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

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

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
7
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

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
