hi def surveillance

[jonesk 0]

I had an interesting inquiry today, a guy called looking for hi def surveillance. he wants to record a motor spinning, and be able to analyze the video at 120 or 150 fps. Is this actually possible without having to go into production video equipment?

You want a "machine vision" camera. There are a number of manufacturers. Here's a link to one:

JAI PULNIX's Digital Machine Vision Camera Boasts High Frame Rate

The TM-6710CL, a Camera Link version of JAI PULNiX’s popular TM-6710 machine vision camera, features non-interlace, quad-speed, 120 fps video at full VGA resolution, and utilizes a 1/2" Kodak KAI-0330D CCD for high image quality (648 (h) x 484 (v)). The camera has simultaneous analog and digital video output. The full-frame electronic shutter with asynchronous reset permits shutter speeds ranging from 1/60 to 1/32,000 sec. The Camera Link digital interface allows easy connection to other equipment, as well as software control for gain, A/D/ ref., shutter, and mode selection. The large 9µm square pixels provide the light sensitivity needed for high-speed image capture and provide a precise geometry for superior definition in any orientation. The camera’s exterior dimensions are: 46.1mm x 39.6mm x 140.0mm. Suitable applications for the TM-6710CL include motion analysis, high-speed on-line inspection, gauging, character reading, high-definition graphics, and high-speed surveillance.

 

They're not cheap! A web search turned up pricing of about $2,400, although someone's selling them on ebay for $600.
