Service and Support for Your Home Security System

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 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.

Responsiveness to Your Calls & Questions About Your Security and Alarm System

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!
