D3 Library and SDK
At the heart of the
flexibility of C_wiz is the D3 (data device driver)
architecture.
What is a D3
Current D3 Library
All D3s listed below are
included with the Evaluation Edition
Download.
As D3s are not
particularly hard to write, our intention is to provide
any D3s developed in the future by ForTotalRecall free
of charge. This statement of intent obviously can not
cover any D3s written by third parties.
All D3s have inbuilt
diagnostics tools, a 60 second trace capability and
fully utilize the C_wiz Test Drive facility to provide
context sensitive online documentation.

Frame Grabber (S2255)
The Frame
Grabber (S2255) D3 saves video frame grabs
(as *.jpg files) from the video stream/s supplied to
Sensoray S2255 4 channel USB frame grabbers attached to a PC. Frequency, quality and
size of the video frame grabs is user definable.
Location, date and time stamps are automatically
embedded in each video frame grab to provide an audit
trail.
Possible
uses include:
o
Radar sweep
capture - many radars have an analog video out option which can
be used to drive a remote monitor - or a video capture
device.
o
Wheelhouse
monitoring.
o
Engine room monitoring.
o
Passenger
monitoring.
o
Monitoring
of patrol boat boarding operations.
As noted
above this D3 only supports the Sensoray S2255 4 channel
USB frame grabber. The Windows device drivers for this
device are pretty simple (putting it kindly) and do not
support the Multimedia SDK (Software Development Kit)
from LEAD Technologies. This D3 would not exist except
for the rather unique characteristics of the device -
you can configure it to only supply video frames on
demand. This means that the PC's USB only has to handle
a maximum of 1 video frame per second per channel per
device as distinct from up to 30 video frames per second
per channel per device for other USB frame grabbers such
as the Belkin Hi-Speed USB DVD Creator. This means that
the PC's USB bandwidth is not swamped by irrelevant data
streams and can therefore be used for communicating with
other devices.
The companion
Frame Grabber Disk Manager D3 enables a user to ensure there is always space
available
on the disk drive that contains the video frame grabs
by, if necessary, deleting the oldest in blocks of 1
hour.
This D3 is
used in conjunction with the C_wiz Video subsystem which
allows the user to view in
real-time, play or plot modes appropriate video frame
grabs completely synchronized to all the other data simultaneously captured.
