WESTFORD -- Mutualink, a national company with offices in Westford, on the East Coast and in Puerto Rico, will have a hand in upping security at the large Fourth of July celebration in Boston this year.

The Connecticut-based business touts itself as providing an interoperable communications-sharing platform.

Mutualink, which formed in 2006, is working with Boston officials for the Boston Pops Fireworks Spectacular this week, which has been moved from Friday to Thursday, due to the potential for inclement weather from Tropical Storm Arthur.

With high-tech software made available to agencies like the Boston Police Department and Massachusetts State Police, Mutualink developers say their program helps various agencies connect so they can communicate and share data instantaneously.

Surveillance video from nearby businesses who opt in to the program can stream their data to emergency responders with the click of a button.

The Boston Fire Department, for example, can pull up a floor plan of a building on a smartphone before racing into a structure fire. A nearby mall can share its camera footage with an officer on duty responding to a dangerous call.

The company's programs have been developed for schools as well, so in an emergency, a teacher could push a button and stream video of an ongoing crisis to a local police department.

"We take their existing communication infrastructure, enable it onto a secure Mutualink network, and that allows anyone on the network to access the communication assets on a permission basis," said Bob Galvin, business-development director for Mutualink's New England offices.

"It means when you enable your communication assets on your network, no one can access those assets unless you invite them."

"Assets" include maps, radio transmissions, video and other data files, he said.

The technology is also being used in a few cities in Brazil as officials maintain security around the ongoing World Cup games.

In the past, Mutualink has partnered with officials for the Boston Marathon and the Super Bowl. They also assisted in the aftermath of Superstorm Sandy.

Galvin said Mutualink has partnered with not only Boston police and fire, but EMS teams, the MBTA police and several local businesses, including the Prudential Center.

This year marks the first time Mutualink has assisted with the Fourth of July celebration. Mutualink became more involved with Boston Marathon security in the wake of the bombings, as well.

Galvin, who previously served as police chief in Norwell and had a 32-year career in police work, said this sort of assistance is paramount to providing safety. And, he said, it eliminates the problem some police departments run into when private organizations are reluctant to share information.

"Think of a private mall or a casino, they're very reluctant to share the video in an atmosphere where they have to cede control of those videos," he said. "We allow them to continue to control the video and they share it only when they want."

Galvin said since the Sept. 11, 2001 terrorist attacks, interoperable platform sharing has become a growing trend in modern security. It was brought to the forefront, he said, when New York City officials were unable to talk to one another and coordinate strategies as they headed into the collapsing Twin Towers.

He added the company is excited to help out Boston this year for the summer holiday. Mutualink is also partnering with Dartmouth and Somerset police to explore other avenues for development.
