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.

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.

Everyone in the office (especially Amber!) is so responsive and friendly, and Steve, the owner, is really on top of everything! They are quick to answer any of my questions and squash any concerns.

In the middle of last night, we had a malfunctioning heater in our garage which caused the garage to heat to 120 degrees - the Bull Dog system alerted us to the heat problem, a representative from Bull Dog called moments later to follow up and our Bull Dog representative (the guy who designed our system years ago and taught us to use it) followed up this morning to find out what happened and how they could help. We just couldn't be more pleased with the service from Bull Dog and count ourselves fortunate to have them as our security/fire safety providers. We recommend them highly.

Theresa of Eyes on U installed a security camera system in my home 10 years ago. A couple of years…read morelater their app stopped working basically making the system useless as far as getting notifications. Also their DVR is working on constant emergency setting otherwise it won't work. There's no contact or customer service with this company. Theresa is not the most "up front" honest or professional contractor I've dealt with. Probably a good thing they're only doing businesses now as they don't have the know how on where to place the cameras because I suggested where all the cameras were to be positioned. Thinking about it....think they were just starting out back then. Really hope for their business clients they've improved with time and experience.​​​​​​​​​​​​​​​​​​​​​​​​​​​

I called this place and spoke to Theresa who provided a lot of information. The very first…read morequestion I asked her was whether or not they provided residential service, and her answer was yes. Then, we discussed DVR v NVR and some other aspects about their cameras, cost, and service. I requested a technician come to my location to provide an estimate, and she took all of my information--name, address, phone, time availability. She assured me I would hear from someone "within the hour" to confirm when the tech would arrive. It's been two weeks, and I'm still waiting. If I'm paying for a several thousand dollar system, I shouldn't have to chase the company who will provide the system. It's an omen for the level of customer service I'm likely to receive down the road.

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++!

Last summer, we had a break-in at our condo entrance, and found a need for a Full Length Interlocking Door Guard. (Highly recommended as burglars love to shimmy a screwdriver between your door and lock & open into your place easier than a SPAM can.) Pro Video Security let us select the guard. They gave a great bid to put install. We even chose to do 2 doors, given their great rate. Flash forward to 6 months later we found a small (but significant) installation error on one of the doors. Rather than haggle and hassle, they came right out and fixed it at ZERO extra cost. (As expected.) On top of that: The fix came right on time. We caught this picture of a rather infamous trio (USPS is after them) trying to break in and being foiled by the door guard. SEE PIC.

I wanted to be able to keep a watch on the dogs and also of course on my house in general. I bought the equipment from Provideo and I am all the way in California, so I had a local person install the equipment for me, and Perry took over the remote customer service, which has been far above and beyond what anybody could ever expect from customer service. If anything goes wrong, he is right there ready to help me fix it and get it up and running again. I could probably find someone locally, but there is no way I would ever find such great, friendly, knowledgeable customer service. So wherever you are in the world, these guys are the best! Thank you, Perry!
