BusSecure
is an industry-specific security camera system developed to help solve problems
experienced by fleet operators. It is a digital video recording system that can support up to four cameras
in a mobile environment and store captured images in a vehicle-mounted digital video recorder (DVR).
Images can then be viewed and examined later.

ECORDING
The central component of the BusSecure system is a high-quality DVR, which records images from up to
four cameras (monochrome or color, NTSC or PAL) with single-channel audio and information such as
the time, date, and vehicle number. Image storage capacity can be adjusted by recording speed, selected
resolution, and drive size.
The DVR begins capturing images as soon as the vehicle’s engine is started and continues to record as
long as the vehicle is running. When the available storage capacity is full, the DVR will automatically
purge the oldest image data to make room for new image data. Tagged images (images recorded
because of alarm activation) can be protected from being overwritten for a user-designated period of time
(the default setting is 30 days) or can be protected from being over written at all.

The captured digital images are stored as monochrome or color files, and are taken from the DVR and
downloaded to a computer with the BusSecure WaveReader
TM
software. The DVR connects through an
Ethernet connection to a standard desktop PC or Laptop installed with a Windows 98/2000/NT/XP
operating system. When the DVR is connected to a PC or Laptop with the WaveReader software, images
can be viewed and transferred to long-term storage media such as DAT tapes, floppy disks, or recordable
CDs.
