Need some help on security

Since Apple can't loan me one of these, I need some method of securing my iPhone to an inanimate object for anti-theft purposes while I shoot time lapse shots.
My plan is, to connect my iPhone to the charge cable and set Activator to play an alarm when it's disconnected in any way. Plus, I have iLocalis and Locktopus as a failsafe.
However, all of these won't work if the iPhone can be turned off.

So, what I want are:
1. An alarm that can only be shut down via a password, and can be activated by Activator
2. A mod to prevent complete power off of the phone. This also has to disable the lock+home shutdown as well as the power off slider.
3. A mod to temporarily disable the headphone jack.

Can someone help me out here? Thanks.

 

Anyone? Please?
