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.

Would definitely recommend to anyone looking for alarm monitoring.Response from the ownerHey, Mark! Thank you for sharing your feedback. If you'd like to refer a friend or family member, head to guardianalarm.com and you'll be able to claim a reward! doug H. ★★★★★ Your company is the best! Thank you!Response from the ownerIt is pleasure to service you. Thank you for your business. Scott H. ★★★★★ I have been a customer of Guardian Alarm for many years now and have had a wonderful experience with their service. My relationship started when I met Scott Frenchik, my sales & marketing person. He is very honest and provides the products and services that I requested. I was never oversold and have had regular communication with Scott as we bought & sold residential and commercial properties. I use Guardian Alarm exclusively for all of our properties. I have had a couple of service calls and Guardian's technicians always have resolved our problems. Overall, I am very satisfied with my Guardian Alarm experience and would highly recommend Scott to work with in customizing your property alarm needs. Thank you Guardian Alarm and Scott!Response from the ownerScott - Thank you for the 5-star review and for trusting Guardian with your security needs. We'll be sure to pass on your kind words to Scott. Remember, if you ever need assistance, we're available 24/7 at 800-STAY-OUT. Thanks again! David ★★★★★ I have had a lot of experience with various home security service companies over the years. Researching and choosing the home security that is right for you can be a daunting task. I found Executive Security Consultants (ESC) to be outstanding. The owner of the company discussed my home security needs over the phone and then met with me at my home to finalize the details. The security professionals at ESC appear to have my best interests in mind and their in-house installation team is neat, prompt, courteous and knowledgeable. The up front cost for ESC to install my home security system AND the monthly monitoring fees are far less expensive than I found with the national providers who describe themselves as but seldom seem to deliver "full service." ESC provided and installed everything that I needed and left nothing to DIY. ESC is a local, central Ohio company that I can count on when I need service or support in the future. In short, I highly recommend ESC for your consideration if you are looking for a home security service company.Patricia L. ★★★★★ The technician was timely, professional, kind and thorough.Response from the ownerThanks, Patricia! We appreciate your feedback. Tonya S. ★★★★★ Excellent work and service!Marella W. ★★★★★ Salesperson Traci Ryan is fantastic! Knowledgable, professional and very personable! Wonderful experience for me with Guardian! I highly recommend!Michelle P. ★★★★★ Everything went smooth and it’s really easy to use. No surprises just great security.Craig S ★★★★★ 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 ownerCraig,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. js_loader
