iPhone to PC Issues

[jeremykeys]

Here's the skinny! I really want to be able to use my old iPhone 4 as a video camera. I'm sure I can do this. The thing is I don't want to record the video data onto my phone but directly onto my computer.
I have a dedicated music computer that has no firewall and no virus protection so it never ever goes online. Cubase just runs so much better this way. That's my DAW of choice.
What I really want to do is be able to do, for example,is play my Kronos while simultaneously video taping it and recording the audio. I really don't want to have to go through all the trouble of transferring the video to my computer after the fact. AS far as I'm concerned, I most absolutely should be able to do this.

So far I've had absolutely no luck at all.

Can anybody help me? Please?

There must be somebody who know exactly what I need and can tell me how to do it!

Thanks in advance as always!

Jeremykeys the eternally hopeless!
