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.

Larry M.
Very knowledgeable salesperson/installer. Very courteous and precise in what he did.
Response from the owner: Larry,I liked that you mentioned the salesperson and the tech was the same person. We do not have pushy sales reps. Instead we send out knowledgeable technicians who are qualified to design a system for your home and at the same time educate you on the technology. That way you can make an educated decision on what equipment you will want to purchase. Thank you for the kind words and your business.
Jeff S.
