National Scientific has integrated real-time streaming video into a modular security system based on Linux 2.6 and tailored for school bus applications. The “location aware” Travado IBUS system, equipped with global positioning capabilities, logs students onto and off of the bus by using a card reader or thumb print scanner. The device stores that data along with details of the date, time, and location. When it arrives at school, it uses a Wi-Fi terminal to upload the data over the school's 802.11x wireless network to a companion Windows XP-based system.

In its most basic configuration, the Travado system combines data capture with global positioning and wireless communications. Other technologies that can be incorporated into the modular system include high-speed cellular telemetry, biometric identification, RFID, and remote engine performance monitoring. By integrating IP-based full-motion video and audio over Wi-Fi or cellular into the system, Travado gives administrators “real-time eyes and ears in any kind of vehicle,” said National CEO Michael Grollman.

The company built Travado specifically “to be expandable and open to Linux developers and other related communities, so that other OEMs can profit by talking the platform to new applications and areas,” Grollman added.

Target markets extend beyond school buses into the military, law enforcement and homeland defense realms.
