As shown, recording at Picture Quality 2 will provide twice as much recording
time as recording at Picture Quality 6 (20 kB versus 40 kB image size)
because the images are compressed more at Quality 2. The user should try
different Picture Quality settings to determine the optimum choice for their
situation. Note that the Picture Quality for all the cameras is the same.
See the Recording Capacity section further in this manual for estimated
recording durations for different Speeds, Image Qualities, and hard-drive
sizes.
3.3 Repeat Record
When the DVR has recorded enough video to completely fill the hard-drive,
the user has the choice of making the system stop recording (thereby
retaining all of the information) or allowing the system to start recording over
the information on the hard-drive. This latter feature is called ‘Repeat
Recording’ as the system will record repeatedly over the information on the
hard-drive every time the hard-drive fills up. If enabled, the system records
over the oldest files first before recording over the latest information. Choose
‘ON’ from the Repeat Record menu item to enable this feature.
If Repeat Record is ‘OFF’ and the hard-drive has been filled, the DVR can be
made to start recording again by pressing the ‘REC’ button for 5 seconds.
3.4 Record Audio
By turning the ‘Record Audio’ feature to ‘OFF’ then no signal will be recorded
from the audio input. This feature is useful if no microphone is being used as
hard-drive memory space will not be used to record the unnecessary audio
channel. At slow recording speeds, this can amount to a considerable saving
as the audio recording uses about 15 kilobytes per second when recording.
3.5 Delay-On Time
The Delay-On option uses Smart-Start that protects the DVR from transients
and voltage swings during vehicle startup. When Delay-On is set to ‘0’, the
system will start up as soon as the vehicle ignition is turned on. When the
‘Delay-On’ time is set to ’15 SEC’ or ’30 SEC’, then the system will not power
up for the first 15 or 30 seconds, respectively. This allows for the vehicle
voltage to stabilize and provide a clean power source to the DVR. For Delay-
On times greater than 30 seconds, the DVR will not power up for the first 30
seconds. After this the DVR will power up but wait to start recording for the
remainder of the Delay-On time. This feature is very useful when the driver
does not pick up the first passenger for some time after beginning the run.
The Delay-On times can be set to ‘0’, ’15 SEC’, ’30 SEC’, ‘1 MIN’, ‘2 MIN’, ‘3
