The NHL EDGE puck- and player-tracking system was developed closely in tandem with SMT. Most recently, the league has installed four 4K cameras in each of its 31 arenas. Two are positioned directly under the centerhung videoboards to provide a complete look at the offensive zone for sustained possessions in the zone, power plays, shootouts, etc. The other two are high up in the ends of each building, offering a view of the entire ice surface — a view preferred by coaches and other team-performance personnel.
Although the tracking system can essentially plot out its own charts and data sets, Lehanski says, the cameras are an essential part of the complete workflow.
