Reliable, Affordable and Professional 1st Security was able to install and upgrade my existing system within 12 hours of my initial request. They were very professional and thorough during and after installation process. They didn't try to push or hard sale any products and most of all they "listened" and "fulfilled" to what I expressed as my needs and wants in a security system. They were able to match--and in many ways beat--competitive offers I had on the table. I would highly recommend them to anyone in need for a reliable and professional security team. Thanks Larry.

Customer Experience I've been pretty impressed with the level of service and product knowledge shown by this company. Everything from the initial sales call to the to the scheduling of the install, to the install. The techs were prompt and professional and were very patient while running me through how the system works.

Great customer service After much research on the internet of alarm companies, I decided to go with 1st Security. They had great reviews, no BBB filings and they seemed to have state of the art equipment. I spoke with Larry and Kelly and they were both very helpful. And most importantly they were not PUSHY! I spoke with some other alarm companies and felt like I was dealing with a used car salesman. No pressure at all from 1st Security. I gave them a 4-star review instead of a 5 because I have not been with the company long enough. I will review again after a few months. But as of today I definitely recommend them .

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.

Awesomeness! From initial presentation to the after sales service, I have been very impressed with the fabulous service and attention from the team. They did an awesome job of making me feel secure in my new home. The pricing was the most competitive as well. I am so excited by having a smart house tailored to my needs at a reasonable cost. It also is great to support a leader in the field but also a local MD business.
