About Brookline, New Hampshire

Located along the Massachusetts border in Hillsborough County, Brookline is known for its quiet charm, outdoor recreation, and excellent schools. It’s home to the well-loved Andres Institute of Art—a mountaintop sculpture park that draws visitors from across the region—and the scenic Potanipo Pond, a popular spot for fishing and kayaking.

Founded in 1769, Brookline has retained its historic character while evolving into a commuter-friendly town with strong civic pride. Community events like the annual Brookline Winter Carnival and the Fourth of July Parade are local staples, and the town’s commitment to safety and quality of life is clear in everything from school investments to public works.

As Brookline continues to grow, so does the need for intelligent, reliable building security systems. That’s where BSISS comes in.
