The camera on my I-pad is restricted, but I dont know the password/code.
To remove the Restrictions passcode you will need to either...
Restore the Device as New...
from a Backup created Before the Restrictions Code was set....
Restore from Backup
If you don't know the Restrictions passcode, then you must restore it as New:

You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
