An improved security system for monitoring passengers aboard vehicles in real time uses existing off-the-shelf computer technology and an associated GPS system and wireless Internet to enable peripheral devices capable of obtaining a variety of data aboard a vehicle and transmitting that data to a remote location, including a stationary location where the data can be monitored. The method connects power derived from the vehicle, with a wireless Internet and GPS enabled laptop to enable tracking of the vehicle. Additionally, peripheral devices including cameras, audio/visual displays and identification means are associated with the mobile laptop, enabling the system to track individual passengers aboard the vehicle.
