“I am in looooveee with my security system!! In these times, it’s all about convenience and peace of mind and this is exactly what this security system gives you. I can do literally everything from my phone. I can adjust my thermostat, lock my door, activate/deactivate my alarm plus tons more. To top it off, it’s very affordable. The customer service is amazing as well. The technicians explain everything about the system in detail and have you demonstrate back to them how to use the system. The response time with the police is extremely quick (I learned this by accidentally setting off the alarm). I definitely made the right decision in choosing 1st security!!!”

“Great Service!
We couldn’t have been happier with our service and installation. Jeremy did a great job describing the benefits of a 1st Security alarm system with out “overselling”. Larry did an excellent job installing the system. He was on time, didn’t leave a mess, and was very helpful in walking us through the security panel interface. I highly recommend 1st Security.”

“I honestly wish I could give more than 5 stars!! 1st Security USA was by far the best decisions I could have ever made when it came to alarm systems. I heard from ADT, Vivint you name them I heard from them. But the customer service and professionalism that they displayed was what sold it for me. You could tell they had your best interest at heart versus your wallet. I had Larry install my system and if you get your system definitely ask for Larry!! He gave me so much advice on being a first time homeowner and how in the future I could protect my house as my family grows. He even fixed my lock that I’d put on backwards (it worked though)! Thank you Larry for all the advice and making sure my house was protected!! Remember ask for Larry he’s the best!!!”

“Amazing system! Did a lot of research on alarm systems….so glad I went with 1st security! They came to my house and explained everything to me, were not pushy at all. Came and installed the system a few days later….took the time to explain everything to me and did an amazing job with the installation. And the price is excellent, both the installation fee and the month to month. So happy with my decision.”

“I recently had 1st Security install a system in my new house and so far have been very pleased with all aspects of the system, from the initial estimate to the installation to the functioning of the system itself. Jeremy did our initial estimate and provided us with a thorough explanation of the system. I already had done a significant amount of research comparing ********* to *** and some of the self-install options, but Jeremy was able to provide even more information and help me to understand better the pros and cons of each approach. Larry did our installation and also was very friendly and knowledgeable, explaining each step of the installation process and providing me with a tutorial at the end. My wife and I have had no issues with the system so far. It is very intuitive, and we have been able to customize it to fit our unique needs. I highly recommend considering 1st Security for anyone looking at installing, switching, or upgrading their security system.”

“Your protection comes first at 1st Security USA.
Jeremy was punctual and professional. The appointment was easy to make with fast scheduling. I received an in-depth presentation and walk through of my home. He was very responsive to my questions and family’s needs. There was no pressure to buy or add equipment I did not want or need. My new system was installed two days later. Larry the technical adviser was amazing. He was knowledgeable and friendly. He installed my system with no problems. He took the time to give us a lesson on how to use the app and new system. A few days later I had a question and he responded right away. I loved the system so much, that I referred my mother. Her system was installed a week later.

I feel so protected knowing my family is safe using 1st Security Alarm company. I have the confidence of knowing that I can upgrade my system at any time. I can not thank Jeremy and Larry enough.”
