Default Lockscreen camera with password?

I'm running a rooted version of Samsung's default ROM of 4.2.2 on an SCH-i435, and I can't access the camera on the lockscreen while I have any type of security enabled whatsoever. The "Favorite Apps or Camera" option is greyed out in the options menu as long as I use a PIN to unlock my device. Is there any app or tweak that can get around this?
