Does anybody know of a program that can detect a modified file in a specified folder and then upload that specific file to an FTP server ?

To be used for CCTV cameras as and when motion is detected to upload immediately.

A friend of mine has had 2 burglaries within as many months and on both occasions the thugs searched the premises until they found the recorder/PC and took off with that as well. So............no pictures !

I looked at Filezilla but this cannot detect a modified file automatically.
