Is it possible to transmit the video data of this camera module (http://www.sparkfun.com/products/10061) via this Xbee PRO (http://www.sparkfun.com/products/8876)?
Thanks,

No - the XBees cannot send video data.

Ok, they can theoretically if you do an awful lot of fiddling and a very low res and very low framerate but it's not worth it.

How is this arduino related?
How is this related to 'Interfacing w/ software on the computer'?

I've been thinking about this, and, actually, I think that the answer is that yes, you can.

The thing that makes everyone assume that you can't is that the subject line doesn't match the camera description.

Sending video data anywhere is beyond the capabilities of the Arduino, because the volume of data is so high that the serial buffer would be constantly overflowing.

However, the camera you link to is NOT a video camera. It takes still pictures, and streams the data over a serial port. You can collect that serial data, from one port, faster than the camera sends it, and have the Arduino send that data out another serial port, that the XBee is connected to.

When all the data for one frame has been collected and sent, take another picture and repeat. Then, you have video, although at a very low frame rate.

Now, doing something with all that data on the receiver end could be a problem, but you didn't define the receiver, so maybe it isn't.

Thank you for the replies :)
Do you know how can I interface the camera with XBee? (Which pin goes where...)
I have never handled a XBee  :smiley-red:

TX on the camera to RX on the XBee.
RX on the camera to TX on the XBee.

Connect grounds and power, too.

Of course, I think you are going to need an Arduino in the mix to define WHEN to take a picture.
