Camera/Video Recording

[ANON12345]

I have a test that is continuously activating a product and monitoring some parameters of the unit. If one of the parameters goes past a threshold, the test fails.

This test is run over night and apparently the test only fails at night when no one is around.  I would like to verify that there is a truly a failure during these instances.  I want to setup a camera system that continuously monitors the test and when a failure occurs. I do not save the recordings during the whole time.  I only want to save the instance of the "failure", probably 5-10 seconds worth.

Is this possible? If so, what kind of hardware and software packages/libraries would I need? I do not want to pay for anymore NI software packages.  Can this be done using a python library or something?

Thank you!

Yep, this is certainly "doable".  You set up the Camera for continuous recording using internal buffers in the IMAQdx drivers.  You need some other indication that says "Hey, something happened, start saving video frames from N seconds earlier until Y seconds elapses, or I tell you to stop".

I've done it with LabVIEW, using their Vision Development Module and the Vision Acquisition Software drivers.  I have no experience with Python -- if you want to "do it with Python", I recommend you post in a Python Forum (but don't ask them how to do it with LabVIEW ...).
