        • “The NSA owner **** and sales rep **** has been very informative and helpful in educating us on the system types. They were not the pushy salesmen type. They gave us a fair deal for monitoring. The equipment was free. The install was free. The install was very nicely done with no wires showing. The tech was on-time and clean up was spotless. We love our 2GIG system and the smartphone app. It is very user friendly.We would definitely recommend them to friends and family. The Johnsons - Las Vegas, NV”BBB Business Review

        • AWESOME SERVICE!! GREAT DEAL!!! At first I honestly couldn't believe what I was being told and almost closed my door on the guy, but after he re explained they need the sign out front for advertising because that's how they generate business I was intrigued.I have been shopping around for systems for the last 3 months and I was getting quoted ridiculous prices and the other companies were trying to charge for the upgraded wireless touchscreen home automation équipment that was upgraded for free with NSA. The best part was the monitoring was ALSO more affordable than the others and to a single father on a real tight budget who just bought his first home, that cinched the deal! My door rep was very knowledgeable and courteous and I got the feeling hew actually cared and wasn't just our for a buck, and the installation was done on time and very professionally the very next day! I give this company 5 stars because in my opinion, they earned it!

        • Fast Reliable Service This service was fantastic.... I live in Las Vegas and called Monitronics corporate off there website and was transferred directly to National Security. They installed a new alarm the same day, and beat out all the price quotes of other companies I had called- (most were ADT companies....) The sales guy was very nice and professional and didn't try and "up sell" me a bunch of crap I didn't need- I just needed an alarm system. Bottom line- It was fast professional service at a monthly rate that beat out the other companies, and had the benefits of having Monitronics- instead of ADT

        • After narrowly avoiding a break-in, we called National Security Alarms to beef up security for us. Gary Bender and crew were prompt and professional. Gary took the time to understand our needs, and recommend the best solution for our purposes. Whenever we are away, we sleep easy knowing that Gary and crew have our backs. These people know their stuff! We don't hesitate to recommend them highly!

        • May-11-2015 I have been a customer of NSA for over four years now. I own a manufacturing company here in Las Vegas for over 28 years. My contract recently expired with NSA and I am positively going to be renewing with them. The installation was perfect and so has been their service.
