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.

My task in progress because my application is more complicated than normal. I needed an automotive…read moreremote key card. I shopped around but the most value was ordering it online from an automotive remote site. I interacted with Adam and he was able to show up on the early weekend morning. His text are professional and clear, & he included pictures. Mazda even as far back as 2005 (car was delayed as released as an 2006) used a key card. There is a chip in the card and one in the valet key. Mazda blank metal doesn't have all the slots cut into the blank either. Getting the car to go into reprogram mode didn't work because the console said I need two "keys." However there is a chip in both the medal key and card. So one transmitter set will work, or should have. He drove an hour back and forth to get the other generic key and had to modify it with a Dremel rotary tool so that the key would have tolerance to get through the tabs on the ignition. That didn't work and he is coming back next week to try again with just another chipped key. Didn't charge a trip fee for making a round trip, nor for the generic key that didn't work. I will spread the word within the MazdaSpeed group so they can get help if the elect to get the Mazda key card instead of generic. At least have one original card and one generic real key. At this point I elected to tow it to Mazda DG for them to try with my key. Because if I buy theirs, its considered an "installed electronic part," and they won't accept returns. Too risky for $400. If they can do it I just pay for 1/2 hour of programming. Worst case I have to buy their key, mine is also OEM (not eBay/Amazon).

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!

They transferred our numbers but couldn't activate my watch for a month. They still charged me. They also added things to my internet that I did not want. Cameras and streaming services that I don't need. They said it would not raise my payment, it did. The part that bothers me the most is that there is no accountability. No one will take ownership and rectify the problem. It's always "the online people versus the in-store people" and no one can do anything about the other. I am disappointed with Xfinity after one and a half months and am Looking for another service provider. Best of luck if you decide to use them because this headache is not worth the money.
