The Bell Camera is powered from a single-wire, Power over Ethernet (POE) connection by the GS₂ Processor. GS₂, the intelligence of the GRIDSMART System, runs the GRIDSMART Engine, a suite of vision-tracking algorithms grown from a decade of real world testing that builds a 3-dimensional model of cars, trucks, pedestrians, and other objects approaching the intersection. The object trajectories are tracked through user-defined zones at the intersection and follows them until vehicles exit, delivering unmatched accuracy.

Born of the collaboration of all engineering disciplines, humanists, and real-life users, GS₂ epitomizes GRIDSMART Grit with a tough cast aluminum enclosure, a long lasting LED front panel displaying calls in real time, and the flexibility to be rack mounted, stand vertically, or lie horizontally.
