Basic Operation
The Digital BUS-WATCH®
IV
functions somewhat like a VCR, except that the recorded
video is stored on the hard drive, rather than on a video tape. To view the recorded
video or to access the MENU functions, connect a monitor to the Digital BUS-WATCH®
IV using the front jacks labeled AUDIO and VIDEO. The end user supplies the monitor
and the cable to connect the monitor. The Digital BUS-WATCH® IV has several modes
of operation.
SLEEP mode:
In a mobile, battery-powered application, it is critical to minimize power
consumption to prevent draining the vehicle battery, therefore, whenever the unit is not
recording, it automatically enters SLEEP mode. In SLEEP mode, the unit's power
consumption is minimal. The red LED on the Power Switch on the front panel is off
when the unit is in SLEEP mode. Menu access is available in this mode.
RECORD mode:
While the unit is actively recording video, it is in RECORD mode. The
red LED on the Power Switch is on, and the green LED near the REC button is on. The
unit can be placed in RECORD mode in one of three ways: system switch,
programmable timer, and pressing the REC button.
PLAYBACK mode:
While the unit is playing back recorded video, it is in PLAYBACK
mode. The red LED on the Power Switch is on. When the unit is PLAYBACK, the on-
screen display will read PLAY and either "(-" or "-)". This indicates the direction the
video is playing, forward or backward. The direction can be switched by the FF or REW
buttons.
MENU mode:
The MENU mode can be activated any time the Power Switch is turned
on by pressing the MENU button. In the MENU mode, the unit's settings and options
can be accessed. The MENU mode operations are described below. The DVR does not
record when in the MENU mode.
MONITOR mode:
When the Digital BUS-WATCH®
IV
is active, but not in RECORD,
MENU, or PLAYBACK mode, it is in MONITOR mode. The live video from the VIDEO
input is displayed on the monitor.
