I recently moved in to a new (to me) home and wanted to find a company to help me with my…read moretechnology goals. I had previously taken a DIY approach to my A/V and security systems, but wanted to make my new place fully integrated from a technology standpoint. I started researching companies and got quotes from several before making my final decision. I found Kelltech Systems by searching the internet, looking for a Control4 dealer in the Dallas areas. They were Platinum rated by Control4 and had good reviews online, so I gave them a call. Kyle is the lead sales person there and he came out to my home to meet with me in person to talk through what I wanted to accomplish. We discussed options for putting music throughout the home (my home happened to be pre-wired for speakers, but none were installed), surveillance cameras so we could see the perimeter of the house, an alarm system with remote control from an app (alarm.com), and some light home automation including lighting control for some key lights, automated shades for my master bedroom, and thermostat integration. Kyle answered all of my questions on these topics and educated me on some ideas I wasn't aware of (like having the alarm sensors trigger lights to come on when I come home). He sent me a detailed, written proposal a few days later, and made the changes I needed to the proposal so that I could move forward. The install crew that came out was prepared for the work, knew exactly what was to be done, and carried out the work quickly and professionally. They trained me on the system so that I felt comfortable using the features and they left my home very clean, despite having cut in new speakers into the ceiling (a messy job). All that to say, if you're looking for a competent, professional, and friendly company for your A/V and security systems, Kelltech is a great resource. I will say they weren't the cheapest bid I received, but I felt like they understood what I was wanting to accomplish and weren't trying to low-ball me with their proposal. Good work Kelltech!

Highly recommended.

I initially contracted with Defcon One security when I first purchased my home. At the time of…read moreinstallation, John said he was working on getting fire/smoke detection, so I chose to stay with the company on the promise of that and the fact that the previous owner had the security company installed. Fast-forward to today and I don't think the company offers smoke or carbon monoxide detection (or if it's available, I was never given notice to add it to my system or upgrade, etc.). My second issue is the contract itself. Signing a standard 3 year contract is fair and standard. Automatically renewing a contract annually without express permission or written notice is not--and upon terminating my service, I was told I was still under contract. The lack of transparency and notice on this issue was galling, to say the least, and I'm leaving Defcon One as a very unhappy customer. Thirdly, you can notice the hours here on Yelp. If your system malfunctions (which happened, creating a full-on intrusion noise that any code entered into the panel wouldn't shut off) and you have that issue, it's not guaranteed that service comes out and, if so, not necessarily in a quick manner. Lastly, my system malfunctioned again this week as a result of a faulty breaker (which was not apparent). Trying to get someone to come out and take a look (again, as the system was making all sorts of disruptive noise) was difficult as no one was answering the phones and it went straight to voicemail. The only reason this isn't a one-star review is that when visits were made, John was courteous and professional. For the same amount of money, you can have service with a nationally-recognized company complete with 24/7 call center service, fire/smoke/carbon monoxide detection, and a contract that goes month-to-month after the initial 3 year contract. All in all, I would not recommend Defcon One Security.
