Trust me they are the best alarm company I’ve ever used. 2/15/2013

We had nothing but problems with our other alarm company. Finally called National Security Systems Inc and they sent a technician to our location and fixed our alarm! I’m so happy I can finally get some sleep knowing my alarm was working properly. \r \r Had a low battery and National Security Systems sent a tech out the same day and replaced it. more

National Security Systems did a great job! 7/21/2011

I use National Security Systems in all three of my business locations and they're a great company to work with. They provide our building security, fire and access systems. Good systems and excellent service. I lease all of my systems so the service is always free and they have service guys available 24/7. I did have a few false alarms a couple years ago but they responded immediately and installed a whole new system at no charge. I would highly recommend NSS to anyone. more

Once more National Security Systems does a great job. 6/29/2010

They were so responsive once more I have a very positive experience with this company for my 3rd alarm system and I’m now having a new fire alarm installed in my business. The sales staff and technicians were so knowledgeable and helpful. Installed the system for the price they said they would and the tech showed up on time. I could not recommend them enough. Pros: You can tell their technicians are very well trained. more

A+ company 12/14/2009

I have used National Security for my business alarm for the past 6 years. Their IT people came out within 30 minute when my store was broken into and the equipment they installed was instrumental in catching the thief (i have video and security systems). Money well spent. Pros: great response time more
