    Traditional scientific and industrial high-speed (i.e., high frame rate) video cameras tend to be expensive. A typical low-end system runs $8,000 or $10,000 for a low-resolution monochrome camera. Some manufacturers include Redlake, Phantom and Photron.

    to 960 fpsfps.
    Starting in 2007 new image sensors became available that made lower-cost high-speed cameras possible. The Casio High Speed Exilim series, the GoPro Hero3 and the Nikon 1 series are examples. They are priced from several hundred dollars to about $1000 and will make short movie clips at rates such as 300, 600 or 1200 frames/second. Unfortunately, many of these high-speed cameras become obsolete quickly! Check around to see if any are left in local stores or at online dealers. Also, check to make sure that the models you find do have high-speed capabilities.

    ...
    Decrease the distance the object moves in each frame by using a camera with a high frame rate. Most video cameras today run at 25 to 60 frames per second (fps), with 29.97 fps being the standard in the US. Some cameras have options of 120 fps, 240 fps, or even higher. See the page on high speed cameras.
    Tip 3. Treat rolling shutter as a systematic error and apply a mathematical correction for it in your analysis.
