The Trooper™ Basic Installation and User’s Guide 12
3. Record Mode / Schedule
Several important features of The Trooper™ Basic System are contained in the
‘Record Mode/Schedule’ menu, as shown below:
3.1 Record Speed
The ‘Record Speed’ option allows for recording at different image rates. For
The Trooper™ 4-Channel DVR, the record speed is the total speed for all
the cameras combined. For example, if the Record Speed is set to 60 ips
(images per second) and there is only one camera, then that camera will be
recorded at 60 ips. If there are 4 cameras, then each camera will be recorded
at 15 ips. The Record Speed for all the cameras is the same.
The fastest rate is 60 ips (images per second), the rate of full speed video for
a single camera. Lower image rates result in being able to record for much
longer periods of time for a given size of hard-drive. The user may find that
the quality of motion at 5 ips per camera (10 ips for 2 cameras, 15 ips for 3
cameras, 20 ips for 4 cameras) is sufficient for most requirements. At slower
rates, the motion becomes more and more ‘jerky’, as in a time-lapse VCR
system. The Trooper™ DVR can record down to 0.1 ips, or one image every
10 seconds. For most school bus applications this would probably be too
slow, although it would extend the recording time by a factor of 100 over the
rate of 10 ips. The recording Speed options are: 0.1 ips, 0.2 ips, 0.3 ips, 0.5
ips, 1 ips, 5 ips, 10 ips, 20 ips, 30 ips, and 60 ips.
Use the ‘LEFT’ and ‘RIGHT’ buttons, or the ‘JOG’ wheel to change the
Record Speed.
3.2 Picture Quality
The Trooper™ TR4-10 DVR uses video compression to extend the recording
time on the hard-drive. The Picture Quality option allows the user to trade off
the amount a picture is compressed versus the amount of memory the picture
takes up on the hard-drive. A higher picture quality means lower
compression, and therefore a higher memory requirement. For an average
image taken in good lighting conditions the Picture Quality options equate to
the following image storage size:
RECORD MODE / SCHEDULE
RECORD SPEED : 15 IPS
PICTURE QUALITY : 4
REPEAT RECORD : ON
RECORD AUDIO : ON
DELAY-ON TIME : 30 SEC
DELAY-OFF TIME : 30 SEC
