RAE Systems Implements Cost Reductions

— Exits Digital Video Recording Business —

SAN JOSE, Calif. — August 29, 2007 — RAE Systems Inc. (AMEX: RAE), a leading global developer and manufacturer of rapidly deployable, multi-sensor chemical and radiation detection monitors and networks for industrial applications and homeland security, announced it will decrease operating expenses by reducing its work force and exiting the mobile digital video recording (DVR) markets.

“We are focused on returning to profitability and sustaining it for the long-term,” said Robert I. Chen, president and chief executive officer. “We are concentrating our resources in our traditional sensing and safety markets and have stopped our current investment in digital video recording. However, we expect to redeploy the DVR technology as the pervasive sensing market develops.”

In the third quarter of 2007, the company expects to record an estimated $4 to $5 million charge, primarily associated with impairment of goodwill and other intangible assets. The charge also includes the write-down of certain fixed assets and severance-related expenses. Except for approximately $200,000 relating to severance, substantially all of the charges are non-cash items. The Company expects these actions to save approximately $1.7 million annually. The restructuring is expected to be completed by the end of the company’s quarter ending September 30, 2007.
