Envirocom, started by Terry Harrell and Glen Gilmore, began comprehensively servicing, installing and repairing electronics equipment in the 80’s. Based in Houston, Texas, these services cover all aspects of security, control and automation for investors both locally and nationwide.

We specialize in unmanned facilities, but our scope of services is very broad. This encompasses all aspects of security and automation including, but not limited to; Consultation and Design, General Contracting, Total Site Automation, 24-Hour Technical Support and Component-Level In-House Circuit board repair. Having repaired all manufacturers’ equipment down to the component-level since the 80’s, Envirocom lends a unique, proven approach to equipment reliability, equipment installation and reliable operation.

Knowing all the intricacies of exactly how every system works from the inside out gives Envirocom the ability to provide the investor a wealth of information available nowhere else. Using our extensive technical resources, we have successfully been able to substantially lower our client’s long-term maintenance cost over the entire life of the facility.

Although a humble company compared to most at the time, Envirocom hit the security and automation scene hard right from the get-go. By the mid 80’s we had begun to draw the attention of different local Houston area investors after some of the innovative commercial work we had done both locally and nationally. 

One of the eyes we caught was that of a young business mogul in the greater Houston area who was building his palatial dream home. He dreamed of, “…a home with a computer brain that implements security and maintenance functions for the whole family,” and knew that Envirocom had just the kind of groundbreaking ideas that could help make this vision a reality. A lot of what was being asked of our company in this project had never been done before by anyone, and that had given our client some issue when it came to even finding a company that would accept the job. However, new challenges only create opportunities for new achievements, and we were up for the challenge. 

In a time when the internet was in its infancy, remotely automating areas such as Security, Access, HVAC monitoring and control, and Lighting control could only be achieved using a phone modem making an install of this magnitude something that needed extra special expert care. Cell phones were still limited and video camera technology was not widely used. Envirocom would need to take a unique approach to things like surveillance since internet video had not yet evolved. We automated every conceivable aspect of our client’s home. From HVAC and lighting to curtains that would open and closed depending on the time of day to a top-of-the-line custom security system equipped with motion sensors, shock sensors with thunder storm shunt detection, glass break sensors all monitored and remotely controlled 24 hours. We even went as far as creating a custom laptop interface that would display remotely a human stick figure on the home’s floorplan that corresponded with whoever was walking about in the home or its surrounding property.
