[SOLVED] Ring file-system for a surveillance server?

Question

In my home, I have a (almost) dedicated (Arch-32) computer to use as a surveillance server. It continuously fetches video from a IP camera using motion and saving various GB of images and videos. Obviously, I have to manually delete older videos when the disk is getting full, but it would be better to have some kind of file-system that overrides the older files with the newer ones when it gets full.
Is there anything like that? Any recommendations?
Thanks!
PS: If your suggestion/solution could only delete videos (not images), better.

One possiblity is to schedule a daily cron job with something like this:
find /home/videos/ -mindepth 2 -cmin +2880 -exec rm -rf {} \;
In this case cmin=2880 (in minutes) equals 48 hours; 'man find' is your friend

Gracias! I didn't know about find's cmin, it is a great option. Exec gave me some problems so I ended up using more than one command. This is the script actually:
find /home/user/videos -cmin +4320 > temp
rm `cat temp | grep avi`
rm temp
The only thing bad about it, is that when find doesn't produce any output, rm shows a error message because there are no arguments. I know that's not the best way, but it works.
Any recommendation is accepted.
Thanks!
