Service and Support

The best service hands down. I was out of the country and my property was broken into. I called and had a tech in my property within hours fixing my broken alarm unit and checking all my windows and doors for security. Way outside of the scope of his job. I can’t recommend them enough. They secure my personal home and rental properties.

Professional Installation

1st Security is the best combination of boutique/Mom and Pop shop where you can be completely be taken care of as a customer but also has state-of-the-art services and equipment that casts a shadow over the really big, corporate companies and their equipment/services. I researched a number of companies and I have never regretted choosing them even for a second.

Love the fact that I can stay in my bedroom and arm and disarm the system. We’re looking at expanding to add the doorbell camera which will allow us to talk with visitors even when we’re not home!

“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!!!” Candi Jackson

“Great company! Larry is the best! Very professional and friendly… He is always available and has helped me out greatly over the years… 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!!!”


Hyattsville, MD, Yelp

“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.”
