There’s no better measure of our work than hearing from the businesses we serve.
Rob Miller, owner of Harvestowne Autobody, trusted Reliant Security with his camera system—and we’re proud to hear how pleased he has been with both the quality of the system and the service behind it.
Thank you, Rob, and the entire team at Harvestowne Auto Body Inc, for trusting Reliant Security to help protect your business!

This is what a large-scale commercial security project looks like.
Reliant Security recently completed a comprehensive video-surveillance upgrade for Universal Galvanizing, installing 70+ cameras and four purpose-built outdoor equipment cabinets throughout the facility.
The system provides management with clearer coverage of operations, property and critical areas—all designed for the demands of an industrial environment.
Reliant does much more than residential alarms. We design and install commercial video surveillance, access control, structured cabling, network infrastructure and complete low-voltage solutions.
Does your current camera system have blind spots, outdated equipment or unreliable coverage? Let’s take a look.

Here we go again! This panel we decided to do a floor mount on wheels since this is a small closet with no room to mount to the wall. We have the feed with about 10ft of cord, so the whole cabinet can be wheel out and out of the way.
Cabinet is not finished, we still have fiber to install for a secondary panel in the plant and tidy to look good! We will have 3 network panels and 71 cameras!

Update from last post. Panel is finished cameras are finished. Long project but customer is very happy! Let us know where we are taking our construction trailer to next?
