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.

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.

Unfortunately, someone took it upon themselves to improperly disconnect my external drive over the…read moreholidays. This ended up resulting in my hard drive no longer working. I truly feared all of my files were gone forever. Wedding pictures, baby photos, and vacations we'd taken over the years. Plus all my music and video files. Adam and the Nerd Rangers saved almost everything for me on a 5TB drive. Their pricing is incredibly reasonable. I'd called a couple services that would have needed me to mail off the drive and they quoted me much higher rates as their minimums. I'm so glad I found Nerd Rangers. They're local and kept me updated every step of the way. I can't recommend them enough. Thanks again guys!

I was unsuccessful with a previous computer store, located on Ogden ave, figuring out the reason my…read morehigh end gaming PC would crash while running games. They ran their tests, charged me a fee and could not replicate the failure. Once I got the computer home, it crashed once the game was being played and they said they did everything they could and I was out of luck. I decided months later to see Adam at nerd rangers. He was very thorough in gaining background on the issue. He asked me whether the other repair shop tried to run the actual game? I was not sure so he went ahead and loaded Fortnite and said he would do his best to replicate the issue. Later that day he reached out to let me know that he believes he found the reason the game crashed (as it did for him) and he felt confident that he fixed the issue. When I went to pick up the computer he reassured me that if for some reason the fix didn't work he would continue to work with me to identify the problem. Happy to report that I've run multiple games with zero crashes and everything is running fine. The level of service, detailed questions and customer care was excellent. Thanks Adam!

I've been wanting to get cameras at my home since moving here a bit over a year ago. I don't even…read moreremember how I stumbled upon 606 installs but it was lucky. Another company I had spoken with had quoted me more than twice the price, I guess because the cameras they use are fancy or something? I don't know, because the ones Ernesto installed are great and doing precisely what I wanted. When I was on my search for home security cameras, I kept mostly finding things like ADT, SimpliSafe, or something else that was largely about selling you the monitoring plan; the equipment I think was less expensive but then you're paying for the monitoring. I am not generally a fan of the everything-is-now-a-subscription-or-service thing nor do I want to be beholden to whatever rates a company decides to charge. Some of those also were self-install options, which didn't interest me at all. They hooked up several cameras at our home to provide various views, including the basement since I wanted to be able to see what's happening down there when I'm upstairs. The system has a hard drive that can support up to eight cameras. We can save photos, videos, and also play back to see what happened earlier in the recording on the various cameras. Although they could have provided a monitor, we don't really have a place for it so we simply have an app on our phone through which we can view the cameras. I'm not sure why, but I thought it would go much more quickly than it did. I have no frame of reference to know how long it should have taken so that's not a criticism. It took about six hours total but having it done well was the most important part. I would highly the crew at 606 installs for their professionalism, reasonable rate, and excellent work.

This review is also about their tech support which we had to call for a lot in the past year: first to upgrade our system as we put it in 18 years ago; and then because we remodeled our basement so they had to come out a few times to deal with construction dust setting things off, moving motion detectors when walls were moved, adding new window contacts etc. Two of their service techs specifically are amazing: Gus and Mara. I feel extremely lucky when they send either of them out. Especially Mara. She stands out as being the most competent service tech - of *any company* I have ever dealt with. She assesses the situation, makes recommendations for better solutions, advocates for the customer if needed, and then executes the solution flawlessly, efficiently, quickly. Again shout out to Gus who is A+ but I have to give Mara an A++!
