Setting up long integration times NI IMAQ 1394 (approx 120s)

Is it possible to configure my camera to integrate over this period of time?

Hello,

Are you hardware triggering your camera? If this is the case, I would take a look at the trigger configuration in Measurement & Automation Explorer (MAX). If not, also take a look at the acquisition parameters and camera attributes in MAX. Could you elaborate on what you are trying to do with 120s integration time? 

[timmkish]

I would like to avoid hardware triggering the camera.

I am writing my own Visual Basic code to interface with the camera.

Basically, I want to be able to use the camera in situations where there isn't a lot of light and still scenes where motion blur won't be an issue.  Right now, the limit for integration time is 1.5 seconds.

Hello,

The attribute you would be looking to modify is the 'shutter speed' attribute. Is this currently how are you are modifying the integration time? The shutter values that you can choose are limited by the camera.

Yes, the shutter speed attribute is what is limiting me to a maximum integration time of 1560 ms.

What are other options?
