Home Security Systems in San Antonio TX


Only the best will do when it comes to protecting your home and family from home invasions, theft, and violence. That’s why ASG Security installs only the most innovative systems using the latest technology. Our ASG connect system utilizes the only “smart” panel available in the industry today. It will never be obsolete or outdated like every other control panel because it gets automatically updated anytime a new feature or version of its firmware is available.

When integrated into your existing home security system, ASG Connect enables you to use your computer, smartphone or tablet to remotely control your alarm, lighting, locks, thermostat, even raise or lower your garage door and more! You can even receive real-time alerts to your phone regarding specific events: who came home, what lights went on…you name it.

Video in the Cloud: TX Video Surveillance For Small Business

Imagine a video surveillance system that can be viewed, operated and managed in any web-browser, smart phone or tablet, from anywhere the internet reaches. No additional hardware or software is needed. Simply plug an ASG Video-enabled network camera into any broadband router, and it will auto negotiate with our high-security servers. No extra configuration is ever necessary.

ASG Video combines the power of the internet with IP video technology to securely store and manage your video offsite in a protected, secure environment so it will be available to you whenever you need it on any device connected to the internet. Gone are the days of expensive and unreliable DVRs, ASG's cloud-based system delivers all your video directly to a secure data center using your existing broadband infrastructure.

Branch History & Timeline

ASG Central Texas Leader

In 2012, the launch of ASG Video boosted growth even more. Now, ASG Security San Antonio aims to be the Central Texas leader in security and home automation.

A Smooth Transition

The company quickly transitioned from a high end automation business to a more affordable offering; thanks to ASG's buying power, manager Eric Garner says that now, “We are able to service a bigger market.”

A Central Texas Leader

In 2011, the sales team began community outreach by booking expos in all of the Central Texas markets. This was a move that helped ASG Security make a name for itself throughout Central Texas, and become the public’s first choice for affordable security, automation, IP cameras, access control and commercial fire products.


Keeping the Roots Intact

ASG Security San Antonio was born out of Integrity Home Systems/ Integrity Systems, a business founded in 2001 by Danny Ward and Robert Wien.

Acquired in 2010

In 2010, the company was acquired by ASG Security; it was an exciting time, with all the branch’s original employees being retained to work for the new ASG branch.
