Lock Codes

Create unique lock codes for each user, and set a schedule to control when the codes can be used. You can limit access by day and time. You can create and disable codes at any time, so there’s no need to rekey or change your locks.

Garage Doors

Garage doors are a key entry point to a property. Now you can remotely open or close the garage door and get a notification if the door is left open when it shouldn’t be.

Reduce False Alarms

Set your security system to automatically disarm when a valid lock code is entered. This is simpler for users, who only have to remember one lock code (not a system code), avoiding the hassle of false alarms.

Why Does My Family Need a Door Devil™?

Alarm Systems and Deadbolts don’t stop violent kicks. Once the Alarm goes off it’s too late. They’re already in your house. If the door frame is destroyed, your Deadbolt is useless. Most families have no idea this vulnerability exists. Criminals do. Until that changes, Door-Kick-in’s will remain the #1 method of entry for burglars.

Users Who Love Us

Good, honest service

“ I had one security company tell me I needed to spend $800 to replace my fire sensors. Liberty came out, showed me how to operate the system and explained the fire sensors didn't need replaced at all. This was a great experience. They're honest, showed up on time for the appointment and did great work. I'll use Liberty for security services going forward ...”

“ Liberty Security Systems was contracted to install a “wireless” security and fire detection system in our home and two (2) detached metal out-buildings. The metal out-buildings due to their proximity required the installation of a "repeater" system to allow the system to be fully integrated. Liberty's personnel worked diligently to optimally locate a single repeater allowing full functionality of all the systems components. We are completely satisfied with our Liberty installed user friendly fully integrated security.”
