Here are some of the companies who showed their wares at this year’s annual event, held in the Javits Center-area Hudson Mercantile Building in Manhattan’s Midtown West. Company principal Marla Suttenberg said about 300 integrators were in attendance at the two-day event April 27 and 28, which followed upon a Boston-located Roadshow earlier in April. “Our lines tell a good story,” she said. “They’re all synergistic in their respective markets,” which include commercial and residential. “We’re a one-stop shop.”
