RAE Rae Systems Common Stock

RAE Systems Inc. (NYSE Amex: RAE) today announced a new version of its ProRAE Guardian software that is currently being used by major customers in the oil-and-gas industry and U.S. fire service. The enhanced ProRAE Guardian software includes major new features and compatibility with all of RAE Systems' wireless gas-detection monitors, including the widely adopted MeshGuard system (see today's related news release from RAE Systems highlighting customer adoption of ProRAE Guardian and MeshGuard).

ProRAE Guardian is a real-time instrument monitoring, management and control software platform that provides mobile-command center functionality with comprehensive real-time display of gas-and-radiation data at any time and from any location. It gives incident commanders and industrial safety professionals rapid access to threat-detection information for fast and better decision-making, and quick responses to alarms.

New ProRAE Guardian Enhancements Include:

• A fully supported cascade mode allowing aggregation of multiple sites into a single, map-based display for real-time monitoring from anywhere in the world.
• The ability to remotely track up to 500 wireless monitors at one time.
• Support for continuous operation environments (24/7/365).
• The capability to consolidate data from all of RAE Systems' and select third-party wireless detectors into a single PC-display for time-sensitive management of critical threat-detection information, including RAE Systems' MeshGuard wireless gas-detection system and other instruments.

Better Control for Safety Pros According to Rob Schnepp, chief of special operations for the Alameda County (Calif.) Fire Department: "Hazmat teams can't waste time setting up complicated equipment during working incidents. ProRAE Guardian's new cascade mode allows multiple units to share data without changing network IDs on any instruments. That means we get up and running faster with less hassle and frustration."

"ProRAE Guardian is changing the way safety managers do their jobs by delivering real-time wireless detection systems that provide game-changing results," said Tom Berarducci, software product manager for RAE Systems. "It puts safety managers and incident commanders in control of their threat information and allows unprecedented access to that data from anywhere in the world and at any time."

• Simultaneous and consolidated monitoring of gas-detection data by global teams.
• Remote monitoring of wide areas.
• Always on, always connected networking.
• Displays, views, and logs of threat-detection data in real time.
