In Our Community
Staying involved and giving back
Guardian Alarm cares about the communities we serve. We’re actively involved with local chambers and organizations to help give back, engage with those living and working around us, and build lasting partnerships. Each year, we encourage our employees to spend time volunteering, giving back to their favorite non-profit organizations, and engaging with their community.
Official provider of Project Green Light
Project Green Light started in 2016 as a crime intervention tool. It originally targeted gas stations since they were seen as crime hot spots but has expanded to include fast food restaurants, churches, apartment buildings and more. Guardian Alarm supports Project Green Light by providing the required indoor and outdoor security cameras that transfer live footage from local businesses to the Detroit Police Department.
