After initial emails and a call with Carlos, we set up a meeting to review our needs at our house. Throughout the entire process, Carlos was prompt in replying and always very helpful and gave us great customer service. When his team arrived to complete the install, the work was also completed professionally. The team of three wore masks and shoe covers when inside the house. They were very courteous and explained everything they were doing prior to doing the work. I was really impressed by the job from start to finish. I'd recommend Carlos and Security Doctors.

We had been discussing installing a security camera system for months. I researched equipment…read morescenarios and contacted numerous companies. As a result of initially discussing the project and meeting with Don at our 2- flat, we decided that Chicago Security Surveillance was the best choice. The price was reasonable for the quality equipment specified. We were sold with Don's thorough explanations of the installation and components. The equipment was installed within the timeline he provided. As Engineer, I have worked with a countless number of contractors on huge projects and on my 2-flat projects over the past 40 years. Chicago Security Surveillance is in my top ten list.

We have had two small issues since then (not to do with the quality of work, just minor snafus) and Don responded to me right away and helped me fix the problem.

I had to use another company in between my two times and was very dissatisfied and that experience made me realize how much better Dupage Security Solutions is. Dupage Security Solutions technicians are responsive, timely, affordable, professional, thorough, patient, and they explain everything step by step, tell you your options, and get your permission before moving forward on another step. I called this most recent technician "my hero" and he humbly smiled and went on his way. :) They aren't 24 hours (that's why I had to try another company- next time I will wait!) so keep that in mind.

About 2 weeks ago I signed up for conceal & carry classes with Glenbard Security. I was…read moreapprehensive as I'm not a regular client at shooting ranges but was considering becoming one, and I wanted to know more about the carry/conceal aspects of owning a firearm in Illinois. The classes are priced competitively, take 16 hours which included qualifying time at a local range, and had ten people attending. Much of the classroom material consists of the Illinois State Police worded laws and restrictions, but the instructor Jason took the time to explain anything that wasn't clear. Being in law enforcement, Jason also shared plenty of practical experience and videos of real-life situations. If you are considering a conceal & carry class I recommend Glenbard Security.
