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.

Because my project involved a custom door replacement that required condo association approval, custom ordering, painting, lock placement, and installation, there were several phases involved. Throughout it all, the team remained professional, responsive, organized, and attentive to detail. Walter, the locksmith technician who handled the project from beginning to end, did an outstanding job. His workmanship, professionalism, and attention to detail truly stood out, and the finished result exceeded my expectations. Chicago Locksmith is lucky to have someone such as Walter that is extremely skilled, professional and pleasant to deal with. I also want to recognize the Chicago Locksmith office staff for their excellent customer service and communication throughout the process. Everyone was courteous, helpful, and a pleasure to work with. Overall, I highly recommend Chicago Locksmith for their professionalism, quality work, and outstanding service.

I'd been looking for an experienced technician to repair a couple of my security cameras for quite…read moresome time. I hadn't had any luck finding a reputable company asking friends, family, or neighbors, so I decided to google local companies who might be able to help. That's how I found Video-Comm. The reviews looked promising, so I gave them a call. Rafael answered and agreed to come over the same day. I told him the cameras over my garage were out, and he agreed to try and repair them. Rafael told me there'd be a service fee plus the cost of labor. He quoted me a conservative estimate of about $300. Rafael and his colleague Diego arrived on time and ready to work. I left them to work in the rear of the property while I tended to my yard. They worked diligently for about three hours before successfully repairing the cameras. It turns out that the wires needed to be replaced. Rafael and Diego replaced the existing wires with copper wires and rewired them. I'm not sure of all the technical jargon, but that was the gist of it. Rafael and Diego had their own truck that had all the equipment they needed. They were quiet and respectful of the property. They cleaned up after themselves, leaving the space as they first encountered it. The final bill was $308. I found Rafael competent, professional, and affable. I'll definitely be calling him again if necessary. In fact, I asked him to send over a quote for an upgraded set of cameras. Now that I've found someone I trust, I'll definitely get new cameras sometime soon.

At a great value as well. The installers were professional, efficient, and meticulous, ensuring everything was set up seamlessly. The quality of their work exceeded my expectations, and I couldn't be more pleased with the results. I highly recommend Video-Comm Security and will absolutely be using them again in the future!

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++!
