Security Camera Systems
For Home or Business
A critical part of your security is video cameras. We will place surveillance cameras in strategic locations around your home or business. When an intruder is detected, video from your cameras can be relayed to your smartphone app. Video can also be recorded on a digital video recorder. HD, 4K, low-light, and infrared illumination (IR) cameras are available for your specific needs.

Our customers say it best:

Community Outreach
As a Christian company, we know that it’s not just important to talk-the talk, but also walk-the walk. That’s why we endeavor to spread the good news of Jesus Christ through our words and our actions. Once a quarter, our staff participates in local missions work in the metro area. Owners Ed and Dana Trim are active members of Word of Life Church in Flowood, MS. They are frequent volunteers for Life Poindexter, the church’s inner-city outreach center in downtown Jackson. In addition, they are dedicated to missions throughout the United States as well as foreign missions, having traveled abroad to places such as Africa, India, South America, and Europe to help spread the Gospel.
We believe that giving back both to our local community and the world is vital to our success. It is an ideal we practice and teach.
