"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."

"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."

"North American Alarm responded to my request for an estimate promptly. Matt came out to my home listen to my needs and prepared up proposal that I could visualize and agreed with. Mark emailed the generalized quote the very same day. I had a couple of questions that were quickly resolved by email. The day of installation went very smoothly. I threw a wrench at the end by asking Matt to do additional work to install a network cable so I could use an app to see my cameras on my phone. It worked out wonderfully and was not extraordinarily expensive. In fact, I believe the overall system was very reasonably priced For the products and the workmanship received. Matt was very respectful of my property, cleaned up after himself, even brought his own vacuum to clean up drilling debris. I am very pleased with the decision to go with North American Alarm, and would recommend this company to others seeking a Camera security system."

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

"The system generally works pretty well, but we frequently get false alarms, often in the middle of the night. Aside from the annoyance of being woken up to a blairing alarm, we now don’t take the alarms seriously, which will be a big problem if we’re ever actually robbed."
