This year I've been all about trying new services instead of sticking with old mediocre ones. After…read moreseeing these reviews, I decided to give these guys a try, and they didn't disappoint. I reached out and Don came by the next morning, and gave me a quick and simple quote that blew the other guys out of the water. He was quick and professional, and fully delivered with terrific quality cameras. 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. These guys will be my first call the next time I need anything like this.

Having quality security was a major priority when we established our new Headquarters in Evanston…read moreIllinois- as our team serves more the 1,600 youth and reaches more than 4,000 family members each year through afterschool and summer learning programs, clinical counseling, street outreach, and parent engagement programs. We required a system that was easy-to-use but delivered quality surveillance footage. The system was designed with panoramic or 360-degree cameras which reduced the total amount of cameras needed to cover key areas and allowed for the beauty of our facility to shine in which we were awarded Excellence in Design for New Construction at the 2017 Design Evanston Awards. Having Umbrella Technologies on the construction and planning team was of great value to our organization and after the system was turned over to our administrative team they were responsive and continued to answer all of our questions. We have on-going training planned with them & are very thankful for the video surveillance system they designed which serves to keep our staff, children and families focused on what matters.

He has always taken the time to help us with whatever we needed. On multiple occasions he took the time to do online demonstrations on their products and answer any questions that we may have had. They also provide advice on camera placement and what materials will be needed to make them operational. Thomas also does not try to up-sell or try to sell you things you don't need. He is honest with his evaluations and his quotes. Umbrella Technologies and Thomas have earned our business for all future camera purchases and I'd recommend them to other colleges or universities for Campus Security Services.

They didn't work and I spent HOURS driving back and forth to have them try again, and ultimately to return them), Mark made copies of the key quickly and they worked! and when we needed some springs in our lock fixed, Mark was responsive! He told me he would arrive in about an hour, and about ten minutes out gave me a courtesy call to let me know he was close by. He not only fixed the lock, he also tightened up the screws and the screen door (that would slam shut previously). Mark was courteous, kind, professional and knowledgeable throughout the whole experience. Definitely going with Mark again anytime we have any key/lock needs! Thank you!
