No efforts to at least neatly stack at the front door.

DO NOT USE THIS COMPANY - We hired Post Alarm in Arcadia, Calfironia to install an alarm system which they did and to conduct daily perimeter walks of our property. As part of the daily perimeter checks, we specifically requested that newspapers be picked up and placed at the front door. Glenn sold us the system, and we later dealt directly with Rob regarding ongoing concerns. The last time we raised this issue, Rob gave us his word that it would be resolved. It has not been resolved. We visited the property today and found clear evidence that the agreed-upon services are not being performed. The pictures speak for themselves. This is apparently how this company treats clients when they believe there is little to no oversight. This is a complete breach of trust. We are being billed for services that are simply not being provided. There is no excuse for charging customers while failing to fulfill basic contractual obligations. Extremely disappointing and entirely unacceptable. No one from Post Alarm has returned my call.

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!
