We know security is a very personal matter and don’t design security systems as one size fits most.  Instead, we take the time to meet with you and learn about your individual security needs taking into account your lifestyle and design of your home.  This unique process allows your Post Alarm security specialist to recommend a customized solution that fits your specific needs and your budget.


We have a wide variety of cutting-edge security products to choose from including our very own Alarm Screens.  Once we’ve worked with you to decide a security plan, our highly skilled installation team will take the time to install your system with great care and respect for you, your family and your home.  All of our installers are our own employees, not subcontractors and are highly trained and friendly.  They will also make sure they leave your home almost cleaner than it was when they arrived.


We take great pride that you have trusted us with your security needs and that trust begins with the installation of the system. Once the installation is complete, your security representative will take the time to set up your smart home services (if you chose that option) and will teach you how to use the system.  They will also be there for you down the line if you need a little refresher course.  Our goal is to be your lifelong security provider so our relationship doesn’t end after the installation is complete.  We want you to feel confident that we will be there for you whenever you need us.


You can also have peace of mind in knowing that once the installation is complete, it is being monitored by one of the best Central Monitoring Stations in the county…and it’s our own!  Our highly trained operators are there for you 24/7 and you will ALWAYS speak with a live person…never a recording.
