"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."

"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"Delivery was delayed due to credit inquiry. After the concern was raised, shipment was rushed to us. Self installation didn't go as easy. Issue was resolved over the phone. The glass break sensor was a bit sensitive to loud noise such as cabinet door closing and door sensor repeatedly falls off and had to be reattached. Notification of alarm activation was fast and made to the right contact numbers. This prevented false alarm calls to the police."

"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."

"CSI Secure Solutions were very prompt with their communication. The information given was what I requested. I found this investigative service very helpful and very professional. I would definitely use again in the future.

"That's the name I am vaguely familiar with; it's a home security company that is license to ADT franchise or dealer if I am correct.  They were very good.  They were prompt; they were quality.  The individuals move their business.  They were very timely and it was a good experience."

"Yvette Pringle provided courteous and professional feedback to me when I called to inquire about a new home security system.  My situation was unique because we were trying to find something that would work for a deaf person.  I appreciated that Yvette did her research to find out what would work.  She also offered different options in terms of a package and plan.  We did end up going with another company, but I really did want to recognize Yvette for her work.  She was very polite and helpful.
