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.

Absolutely pleased with Executive Security Consultants! Doug and Chris went above and beyond getting our new security system installed on a weekend right before the holidays. No up-selling or over-selling. They were up front about what we needed and had our system going in no time flat. The monitoring app is simple to use and provides the desired amount of detail. We really appreciate being able to arm or disarm the system remotely. This company is 100% professional.
Response from the owner: Craig,I am glad that we were able to take care of your security needs in such a prompt manner. We always try to design a great system that will fit into our customers budget. Thank you for your business.
