C_wiz: for total recall

Low cost, high performance vessel monitoring for Microsoft Windows

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.

Contact Us if you think we don't have your requirement covered.

Frame Grabber (LTMM)

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.
