It's not recording anywhere by default. Go to the camera's index page - the link to the Disk Recorder. There's a Format tab and you'll need to mount CF cards filesystems there if you have "no devices found". Then you should be able to record.

Alternatively, you can mount them from the command line (use telnet, ssh or http://192.168.0.9/phpshell.php). The CF cards will be detected as "/dev/hda1" and "/dev/hdb1" :
mount /dev/hda1 /mnt/0
mount /dev/hdb1 /mnt/1

Or, if you want them to be auto-mounted after reboot add proper records to "/etc/fstab", example:

# device             mountpoint         fstype     options            dump/pass
dev/hda1            /mnt/0             ext2       defaults           0 3
dev/hdb1            /mnt/1             ext2       defaults           0 3

The sensor is able to provide only 15fps max at full resolution and the compressor decreases it a little. So, you'll need to either change resolution or set binning.

The JP4 and other formats can be set from the Camera Control Interface (a link from the camera's index page). I attached a picture - after you open the interface click on the camera icon and then on the "more details" link near the small preview picture.
