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.

We cannot thank Executive Security Consultants ENOUGH for all they've done to bring peace of mind to our family. We were remodeling our home when it was broken into TWICE by thieves coming back to steal more. They stole thousands of dollars worth of equipment and numerous belongings of our own, leaving us (to put it mildly) feeling unsafe and beyond unsettled. We were so worried about moving back into our home, that we called Executive Security Consultants and they came out the next morning to secure our home and garage. Their employees are stellar, professional, and understood completely the state we were in before, during, and after installation of the system. The entire process was seamless and easy. We were also pleasantly surprised at available options and the price affordable and, well, PRICELESS! The ease at which our system operates from our phones makes us feel even more secure whenever we are home or away. These are trying times and the police and others suggested there will be an uptick in crime. We HIGHLY recommend Executive Security Consultants to secure your family. I can't adequately describe how much better we feel now that we have it.

Guardian Alarm is better and more attentive to their systems installed in your home than ADT in my humble opinion. Also they are a local company making them much more easy and quick to access, and one other point that all would appreciate is that their prices are way lower than ADT. ADT leaves much to be desired. Yes I had a bad experience with ADT when I needed it the most during the time of a funeral. So choose wisely.

I am pleased with the installation of my alarm system. Tim, the technician, went beyond my expectations by ensuring that all my expectations were met and didn’t mind problem-solving to resolve issues during the installation.
Phil S.
The alarm system employee sent was outstanding, and more than likely would not have came, had I not contact Mark from sales on a new updated system. Once on the job, there was more too it, than a battery or changing the keypad. All fixed.
