"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"For Security Systems, this is the place to go. Yes, I had ADP quote my project, but Modern Tech was by far the best option. Not only is it a local company, but the professionalize, value and price made it an easy decision, plus there was not a three year contract! Robert was the installer and he was fabulous at explaining options (personalized to what I needed) and how everything worked. He was also very responsive to the follow-up questions I had. I highly recommend using this company for your surveillance and alarm system needs."

"I had a sensor that was broken on an old system. Chad contacted me for the repair. With a reasonable estimate for the repair, I asked about upgrading to a contemporary system. Chad explained everything and gave us a great new system with a small increase in our monthly cost. Chad was very polite, professional, and knowledgeable. I recommend Custom Protection LLC for your alarm needs."

"Good price. Typical monitoring services. My only real issue is that most of their account servicing needs to be done via snail mail or over the phone--they do not have a website to update contact info, billing info, or other details."

"We just replaced our outdated and expensive security system with Smith Thompson Security. Our contacts with sales and support were friendly and helpful. The installation technician said our old system was usable and up-gradable to the new technology. We added cameras as well. The tech was knowledgeable, friendly and full of tips on using the system. Total monthly cost for this new improved security was about half of what we were paying out to the old national company. So far, we are very, very pleased with our choice."

"Frontpoint is very easy to use... it's one of the only DIY services out there. You can install all the sensors yourself (they are all wireless). You stick them where they need to go with very clear instructions, and if you do need help Frontpoint support is excellent. You always get someone on the phone, and they are always happy to walk you through any issues you're having. I've had issues a few different times with dead batteries in a sensor, or misplacement of a sensor causing issues, and in all cases they've resolved the issues quickly over the phone. Because of this, I can manage the system myself (and that's pretty much installation upfront, updating equipment every few years/as needed, and support very rarely). We've yet to have a breakin or anything like that, but we've had several false alarms where my wife accidentally set the alarm off... and in those cases, Frontpoint calls you immediately, asks you for a password, and then asks if you need assistance. Of course we don't, but if they can't reach you... which has also happened... they call the next person on the list (my wife). If they can't reach that person, the cops are already on their way while Frontpoint works down the list of family members, neighbors, etc. to let them know there is an incident at the house and the cops are on their way. This has happened a couple times (due to user error). But it's good to know they have our backs if there is ever a real issue. A+ for Frontpoint."
