Professional Installation of Your Home Alarm System

“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.”

“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.”   —Marc Wernick, TrustPilot
