About Us

Stewart Electronics Stocks, Manufactures and Sells Smart House Parts.


Since 1976 our family owned business has sold and installed a wide variety of electronics in the residential and commercial burglar, fire, camera and home theater markets. In 1993 we became one of the first dealerships in the USA for the home automation industry with a product called the AMP Smart House system. (Obsolete in 1995) Today we continue to support AMP and MOLEX Smart House systems as well as other current brands.

Since 1996 we have distributed electronic products for the Home Automation industry to the retail, wholesale and DIY markets. During this time we have trained installers from all 50 states and over a dozen foreign countries in our automated classroom located in Lyman South Carolina. Since 2009 we have manufactured the ALC line of automated lighting products that are compatible with ELK, HAI & other automation controllers and as a stand alone lighting system. Previously owned by OnQ Legrand and manufactured in China, today ALC products are manufactured in the United States using the highest standards.

Alarm Systems, Home Automation and Home Theater systems, our experience spans three generations of the Stewart Family.

Why Choose Us

For convenience of choice

This is a good spot to describe the difference of finding a local retailer as compared to sourcing everything online from a store that actually stocks most products it sells. Online customers want to make choices and its up to you to provide them with multiple choices, all leading them to purchasing products on your website.

Delivery to all regions

In today’s age of Amazon’s ability to deliver products fast and safe, explaining that you understand the importance of delivering your customers products with speed and accuracy is very comforting. You almost need to convince customers that because you are the manufacturer, no one else can complete on availability and speed of delivery.

The highest quality of products

When you manufacture parts for the industry you sell to, use that to speak about the quality assurance your customer support team upholds. Its hard enough to take money from people online for a product they have not yet even held in their hands, make them question the quality of your competitors and win that customers trust and money.

    We have used Smart House Parts for converting our obsolete AMP and MOLEX customers over to brand new technology. Thanks Tony, your team is always first on our list to buy from!

  • Bryan Thompson

    Getting hard to find home automation and smarthome pieces used to be a pain, not any more. Thank you for always knowing where to find IMPOSSIBLE to find parts.

  • Ann Smith

    With so many places that say they know smart house technology, it took us a while to find the team over at Stewart Electronics. We sure are glad we did. Tony and his teams have been working in this field as long as the technology has been around. They really know their stuff.

    Stewart Electronics has a few different divisions that our family has used over the years. ProtectUpstate.com is where we originally found them when looking for a home and business security system. They installed and continue to maintain everything from day one and we would not have it any other way.
