slow camera speed

[k_norr]

Hi all. I am having trouble getting my camera speed to run as advertised. I am using a Basler A601f connected to a CVS-1450. I am currently trying 30fps, but it will only give me between 20 and 25 (not saving any information). Also, when I try to save a series of jpeg files using grab, the frame rate will only give me about 9fps and slow down gradually. Is my connection to the external hard drive or the drive itself getting overloaded? I'm using a FireWire 400 connection to a Maxtor 500Gb One-Touch external drive. Thanks!

Hi Ken,

It sounds like you might be acquiring your images onto a host computer.  Are you acquiring your images in the Measurement and Automation Explorer?  One thing that could be causing the delay is transferring the images from the CVS to your computer.  Something you can try to solve this is to deploy your program (is it LabVIEW or VBAI) onto the CVS and then connect your CVS to a monitor.  Then in your program display your frame rate onto the monitor using the RT video out vi.   As for when you are saving your data the delay could be caused by your external hard drive.  It could depend on how your program is written.  If you are grabbing and saving each image the time it takes to save to file could be slowing down your acquisition. You can verify this by changing your program to see how long each loop is taking.  I hope this helps.  If you have any questions let me know.

Have a great day,
