You need to describe specifically what you've done to try to enable autoboot, and what the results were.
This appears to be an older vxworks camera, so all you should have to do is
1) copy DISKBOOT.BIN,
2) make sure your card is locked
3) load manually, and select Make Card bootable... from the misc menu.
The cards needs to be formatted fat16 or fat12, but it probably is since that camera doesn't appear to support SDHC.
