William ..

Search around for about two months trying to find a decent company for a camera system for our house. Finally decided to go with SuperMatrix. Their pricing was actually better than the rest. Working with Robin was a great experience very knowledgeable and very detailed. They showed up on time. And the crew was excellent. Very happy with this company and the crew. Thank you.

I was looking for 2 cameras to replace the ones that went out. My cameras use old connections and I checked several places. Super Matrix was able to find what I needed and they worked great. Their customer service was very good.

Mike helped us relocate our phone system from our old location, to our new location when our…read morebusiness moved, and run our fax line through our server so that employees could fax straight from their computers. He also wired up our phones to work straight from the trunk box about 100-feet away. He ran the wiring for our service department building underground to our main office about 600-feet away, along with running all network cabling as well so everything was run from the server and T1 service. He gave us a great deal on our phone equipment, upgrading us from a system that was close to 15-years old. Mike offered his expert opinion and suggestions when needed and provided us with top professional service. I wouldn't think of calling anyone else to handle all our wiring and phone equipment needs, he is the best! Thanks Mike! Michele Rock, Treasurer - Dependable Equipment Rental, Inc.

Several years ago I met Mike on a job and noticed his ability to run cable even to the most difficult locations. Everything was neat, clean and professional, so we exchanged business cards. Over the past several years, I have referred numerous customers to Mike and used his services personally on many occasions including my office. Not only is the work done in a timely manner, but every jack is labeled, terminated and tested. He even leaves several brand new spare patch cables! What a pleasure it is to come out to a job that has been cabled by Mike "The Phone Guy" and simply plug everything in and it works the first time. On several occasions I have referred Mike to customers with very expensive homes that required the highest professionalism for the installation and every job was done with surgical expertise, customer always pleased as punch, makes my job easier and don't let me forget to say that Mike is a licensed contractor, so you don't have to worry about some shady work that never gets completed. The only thing left I have to say is.. If you need a cabling job done right the first time, then I would absolutely without hesitation recommend you call Mike "The Phone Guy". He is an honest, hard-working professional whom I have dealt with for more than 15 years. Mike... YOU ROCK MIKE!!!

San Marino Security Systems installed both an alarm system and a camera system. After a brief,…read moreunpleasant encounter with the other security company P--t, we realized that we needed a security company that would "not just send a sales person " but a company that would do the job. After all, we are talking about home protection, not selling shoes here. The alarm installers showed up on time, introduced themselves, and were very easy to work with. Thank you, Ulysses, Marlin, and Edison. Then we had San Marino replace our old camera system. They did a fantastic job of getting all the cameras to cover the strategic areas. I was impressed! Thank you Dennis, Victor, and Chris. I will soon replace my alarm system and cameras at my business, and recommend San Marino Security Systems to anyone who may be serious about protecting their home with an alarm and camera system. They are the best in the business!

Phil (owner) is super knowledgeable and patient, explaining all the functions and different details of the system to my wife and me. The technicians, Dave & Ulysses, were very professional and respectful during the whole installation. They arrived on time, wore shoe covers inside the house, and cleaned up after themselves at the conclusion of the install. They answered all of our questions and finished in a timely manner. Everything with this process was seamless working with SMSS. From administrator Jenny, technicians Dave and Ulysses, to owner Phil, everyone showed why this company has been around for decades and will be around for decades more!
