The Suffolk County Police Department is unveiling a new Smart911 system that will provide operators and first responders with critical information during emergencies.

Smart911 is a free app available to individuals who live within a police district. It allows residents to create a safety profile for their family.

The person who takes the 911 call can view addresses, medical information, home information, description of pets, vehicles and emergency contacts.

Those who access the app can provide as much or as little information as they want.

Acting Suffolk Police Commissioner Stuart Cameron says Smart911 will even allow users to put in a domestic violence situation in the house that will come up immediately when they call 911.

Suffolk County Executive Steve Bellone says the app will allow the county’s public safety agency to send emergency response teams to the right location.

“When the emergency happens, seconds matter,” Bellone says.

The department is also implementing the Rave Guardian app for victims of domestic violence and others who have previously been provided with in-home panic alarms, which are being phased out.

If the person seeks help, the GPS location can be accessed so they can still be located if they are not at home.

Keith Scott works with The Safe Center Long Island, which proves services to domestic violence victims. He says the Rave Guardian app is a potential lifesaver.

“They could just press one button on their phone, usually people have the phone on them, so it’s an additional layer of protection for survivors,” Scott says.

Both the Rave Guardian and Smart911 apps are free.
