LOUISVILLE - Envysion Inc. will install video surveillance system in about 130 Carl's Jr. and Hardee's restaurants to help the fast-food chains improve profitability, the company said Monday.

Financial terms of the deal were not disclosed between Louisville-based Envysion and Jason and Carl LeVecke, who are related to with fast-food restaurant parent CKE Restaurants Inc., based in Carpinteria, California.

Enysion's hardware system can help Carl's Jr. and Hardee's achieve an additional 10 percent to 15 percent in profitability once it's installed, Matt Steinfort, Envysion's president and chief executive, said in a press statement.

Envysion's surveillance system is designed to identify high-risk cash-register transactions such as discounts, voids, refunds and deleted items at restaurants and retail stores. It's also used for operations and human resources functions, among other things.

Fast-food chain restaurants and brands such as McDonald's, Pizza Hut and Burger King are Envysion customers.

Envysion's investors include Columbia Capital, in Alexandria, Virginia; High Country Ventures in Boulder; and Bear Equity in Louisville. The company started in 2004 and has received more than $9.5 million in investment.
