I was advised by a neighbor about their products and services. They told me that they were happy with the security system and services provided. So i gave them a call and 11 months later, I am also happy with the security system installed in my home. Thank You xtreme security and fire.

Calvin Nelson
Highly recommend this company. They did a whole-house network installation running Ethernet wiring and access points throughout the house, including setting up a network closet. They were very professional and responsive. Because they have a local presence, they were able to come back to my house to make adjustments as needed until everything was perfect.
