NTS Selected as Independent Certifier for Multimedia over Coax Alliance
MoCA Certifications by NTS to begin in Q2 of 2007

CULVER CITY, CA – April 10, 2007– National Technical Systems Inc. (Nasdaq:NTSC) (NTS), a leading provider of quality, conformance and certification testing, quality registration and managed services, announced today that it has been selected by the Multimedia over Coax Alliance (MoCA™) as the exclusive lab to perform certifications for MoCA products.   
MoCA is an industry driven standard promoting networking of digital video and entertainment products throughout the home using the existing coaxial cable. MoCA technology provides the backbone for home entertainment networks of multiple wired and wireless products, including “triple play” technologies (i.e., voice, data and video). During certification, MoCA products are subjected to a battery of tests within a controlled environment to ensure the product will interoperate with other certified products from other MoCA members.
“NTS is pleased to have been selected by MoCA to assist in getting certified MoCA products into the market place,” said Osman Sakr, NTS CTO. “The ability of MoCA members to come to an authorized independent test lab whenever their products are ready for the market will provide them additional flexibility in their product release schedules.”
“Working with an experienced certification provider, like NTS, allows us to provide our members the support and attention they require to get more MoCA products into the market,” said Tom Leacock, Chairman of the MoCA Compliance Working Group. “With the recent news that over one million MoCA nodes are in deployment by systems vendors and service providers, the addition of an independent certification lab was a must.”
