"SafeStreets Home Security was a lifesaver! They had to troubleshoot my 3 floor townhouse unit, requiring many trips up and down the stairs. Finally determined that I needed an entire new alarm system but had all the parts and equipment available. Helped me program the app and set my security codes."

"Art Rosenberger gave me good servie and possibly a good price. It is up to the Knights of Columbus to approve the package. I am getting bad reviews from them at this point in time. Some people feel we just don't need the system in a country church. I don't agree with them."

"Juan did a great job with mounting a large number of blinds in some challenging window openings that I had been struggling with. He is also a very nice guy, and I will be using his services again (likely for doorbell camera systems in the near future). I would highly recommend him."

"Jay was fantastic. He installed my Ring doorbell, full Ring security system with window and door sensors, two smart locks, and two Nest thermostats. From start to finish he was professional, knowledgeable, and incredibly friendly. He took the time to make sure everything was installed cleanly and correctly, and most importantly made sure every device was fully set up and working on my phone before he left. He explained everything clearly and made the whole process easy and stress-free. It’s obvious he takes pride in his work and cares about doing things the right way. I would absolutely recommend Jay to anyone looking for smart home installation and will definitely hire him again in the future."

"I switched from another company to Security One, they use the same equipment. They had to come out and recode everything. I simply switched because of the financial benefit. I have only had them for a few months, and I haven't had any problems with them. They save me some money every month.  When my alarm went off, they did call me."
