This depends on how you plan to power on the camera. Are going to switch the AC power to the camera, toggle a digital enable line, or send a serial command? Without knowing how this camera works it's difficult to say how to turn it on, but more than likely LabVIEW (with the right hardware) will acommodate your camera.
Once you have the camera powered, you can proceed with the acquisition as normal. If there's no way to know whether the camera is powered, you could just call a snap command in a loop periodically and exit when you no longer see an error or you get tired of waiting.
Cheers,
