Global Caché President Walt Keller says his company’s main line of products range from $150 to $400. Suggested list prices for sensors run as low as $70.

For the total package?

Traditionally, costs for smart home systems have been 8 to 10 percent of the overall value of the home.

"It’s sort of like asking how much a car costs — you can go all the way to a Ferrari," Keller says. "In million-dollar or more houses, it could have cost hundreds of thousands of dollars."

But emerging technology has brought prices into the middle-class realm.

"If you are just focusing on the home entertainment system, it can be in the $5,000 to $10,000 range with additional touch panels costing $2,000 to $3,000 per room."

Various products can work on pool, spa and sprinkler systems as well.
