Above a certain rate they are intended for slow motion playback later and not real time use. Cameras that record hundreds or even thousands of frames per second use special RAM on the camera to store a few seconds and then download the frames using network or USB connections.<br> </div></div></blockquote></div><div><br></div><div><br></div>If its for tracking applications, any of the video tracking installations that I have been involved in have used Black&White security cameras with a visible light filter. Those cameras are analog and about 150-300€. Then you need to get a analog capture card though. That could be a Canopus or anything that provides low noise and high framerate.<div><br></div><div>.hc<div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div><br class="khtml-block-placeholder"></div><div>----------------------------------------------------------------------------</div><div><br></div><div>Programs should be written for people to read, and only incidentally for machines to execute.</div><div> - from Structure and Interpretation of Computer Programs</div></span> </div><br></div></body></html>
