Scanning for Ideas: Trouble on the Line? Get Out the High-Speed Video
When something goes wrong with a piece of moving equipment, the first step in the troubleshooting process does not usually involve a high-speed camera that records equipment in action, then lets a technician play it back at superslow speed to spot what’s going wrong.

That’s because
high-speed photography
traditionally called for
expensive equipment,
top-notch lighting,
and an expert to walk
you through the process.
That could all change with
the StreamView-LR, a portable
high-speed video recorder from
Southern Vision Systems Inc.,
Madison, Ala. (southernvisionsystems.com). They want to make
high-speed video the first
resort, not the last resort
in troubleshooting.
The battery-powered
device is reportedly
simple to use with few
controls. Users just point
and shoot. It sends video
at up to 976 frames/sec
to a laptop or PC, which
can be viewed later at
slower rates. Storing 10 sec
of video takes 1 Gbyte of RAM.
A 2.4-Tbyte memory holds 10 hr
of video. For long recordings, users
can mark frames or events for
later playback or analysis. The
camera records in 8-bit mono or
24-bit color, and resolution ranges
from 640 480 pixels at 200 fps
to 640 64 at 969 fps. The 0.6-lb
camera mounts on a tripod or is
handheld.
Troubleshooting with the
camera often leads to process
improvements as well as solutions
to problems. For example, a
company that used the camera to
analyze a robotic cell that was going
haywire as its working speed
was increased found several im-

provements it could make. They
adjusted the loader and reduced
jams. Then, reducing the wait time
between product drop-off and
pick-up increased throughput, as
did removing 0.5 unneeded sec
during a bending cycle. They also
slightly tweaked a cabler so that it
ejected parts more consistently.
