remotely recording video from PC with command lines

Hi,

I wonder if it is possible to remotely control a Canon 110S form a PC.
I need to record short videos every step time that I define and save them on my PC so I can process them.
Can I do that with simple command lines in DOS ?
I have read about PTPcam can I use it for my purpose ?
Thanx a lot !

You can use the PTP extension http://chdk.wikia.com/wiki/PTP_Extension to control the camera from your PC and download files. Both ptpcam and chdkptp can be used for this.

You cannot record video on the camera and have it save directly the your PC, but chdkptp can be used to record the live view.

Can the files be videos or only images ? Can they be downloaded anywhere on my PC ?

What do you mean by directly ? I'm confused is it possible to download videos on a specific place in my PC ?
I don't need to process live videos. I just need to record videos of 10 seconds every 60 minutes and save them on my PC. I also need to record my videos @120fps so I don't think that I can use the live view. What do you think ?

The files can be either.  And you can download them to anywhere on your PC with enough available free space.

reyalp meant that you cannot record to your PC directly from the camera.   You have to record a video file on the camera first and then transfer it to your PC.  A two step process.

Yes.  Or at least you can download a video file that has already been created from the camera to anywhere on your PC.

You don't need live view.   Assuming that your camera supports 120fps recording then causing it to record to the camera SD card for 10 seconds every hour and then downloading the resulting file is very possible.

Dear waterwingz, thanx a lot , this is very helpfull !
Now, my main preoccupation (see the title of the topic) was if I could do everything I described but with command lines in DOS or with a script. Does the PTPextension lets me do it or is it only a Graphic User Interface ?
Thanx a lot !

chdkptp https://www.assembla.com/spaces/chdkptp/wiki provides a command line interface you can use from a DOS prompt, batch file etc. There is also a GUI, but you don't need to use it.

You can also get the ptpcam command line executable from the link in http://chdk.wikia.com/wiki/PTP_Extension#ptpcam
