NYC Marathon chose TBus IP transmission

The 2014 TCS New York City Marathon was first held in 1970 by the New York Road Runners Club (NYRR) with just 127 competitors running loops around Central Park. Today, the annual New York City Marathon runs through all five boroughs of New York City and is the largest marathon in the world.

For the 2014 TCS New York City Marathon, the NYRR entrusted the supply of digital information transport services and a technology push package to New York based IP network and electronic security specialists, Virsig LLC. On the day of the marathon, the temporary system was used to provide increased operational situational awareness, digital information transport for surveillance cameras, voice annunciators, media broadcast, and digital signage including large-screen televisions.

For the 2014 event, due of the limitations of installing signal over long and costly fiber runs, Virsig opted to transport digital signals over less expensive and more flexible coax cable. Allowing long cable runs to be readily deployed across the

TCS New York City Marathon start at Fort Wadsworth, Staten Island, Virsig chose reliable Transmission Bus (TBus) IP transmission technology from Network Video Technologies (NVT). Working in compliance under the National Park Service, U.S. Park Police and the Coast Guard Police authorities, NVT single and 4-channel TBus UTP/Ethernet over Coax transmitters, surveillance cameras, wireless nodes and antennas were installed in strategic light pole locations. The NYC Department of Transportation (DOT) worked with Virsig to keep the power supply to the poles energized at all times to power the temporary equipment forming the cost effective Ethernet over Coax (EoC) transmission network.

The high-availability IP network was installed using RG59 coax with spans of more than 3,000ft (914m) across the open space at Fort Wadsworth, home to the Coast Guard and Army Reserves. Ultimately, close to four miles of communication cable was installed from pole to pole, over structures, fences and high up between trees. In the Race Command Center (RCC), Virsig installed a wall of commercial grade monitors to be used as part of the primary camera viewing station. A Seneca viewing station also was used to control tactical camera operations and Firetide Hotview Pro software was installed on the system to provide monitoring of the network via the marathon’s Smart Wall. This supplied up to 36 simultaneous camera views.

TBus UTP/Ethernet over Coax transmitters and surveillance cameras were installed both on the city’s streets and within Central Park. Above the finish line on a steel Photo Bridge (where ESPN and other media were located on the day of the race), Virsig positioned cameras and wireless nodes to record the race finish and capture the crossing of the finish line by every participant. Another camera was positioned at post-finish to observe the chokepoint (a medical emergency assistance area) behind the race finish.

Early on the Sunday morning of the race, over 50,000 competitors ran across the Verrazano-Narrows Bridge from Staten Island into Brooklyn, on the start of their 26.2 mile journey. A few hours later as large numbers of runners started to enter Central Park, the Virsig technology push package demonstrated its full capability. The monitoring station in the RCC displayed dozens of cameras, which fed real-time data to the race staff and incident commanders increasing overall situational awareness.

On Staten Island, the Jumbotrons and systems that needed information transport worked exceedingly well. The near four miles of cable Virsig strung along with NVT TBus Ethernet Transmitters operated flawlessly. The race went on until after dark, and while the last runners were wrapping up the course at Central Park, the Sony IPELA cameras still demonstrated amazingly bright clear images. In the event of any security incidents, the high-quality recorded camera video would have been available to the marathon’s management and law enforcement personnel for evaluation of evidence.

All together, the massive IP networked technology solution was a success for the 2014 New York City Marathon. For future events, the same system will be used again but in an expanded format.
