-This is just what is off the top of my head I do have more ideas-
Idea: You can get new items that help you break into and steal things.
This fancy tool goes into a special slot where you can use a keybind to use it. When you shoot it at a block it allows you to walk up the wall. When you are walking you can go up / down. [Not just pulls the player up] [Can also use other tools when climbing]
This tool will cut a hole in glass big enough to allow the player to squeeze through! When the player goes back through the glass they can replace the glass making it appear as if the glass was never touched. [Can be used with Grapple Hook]
This marvel will shut down add redstone [And other things from this mod] for 2 minutes allowing the Thief to get in and out without setting off any alarms! The distance is only 100 blocks.
This marvel is a big metal door witch is hard to bust through. It could be a code door or a remote door witch only opes at cretin times of the day. The Vault door is connected to a security terminal and the alarms. Thus the Thief will need to use a Micro EMP or some other gadget to open the door without setting off the alarms.
This is the hub of all of your security needs. With a built in firewall this baby is hard to crack. It allows connection to security cameras, doors, and etc. If something is wrong the terminal will alert you.
This Camera allows the player to view what is going on. [Yes I know this is in Security Craft] With a build in light and alarm to ward of unwanted this is good for keeping track of areas fast.
This is a remote door controlled via a portable device and will only open if the device is authorized to. [Can be Hacked] If a EMP is used the door will NOT open untill the EMP wares off. Same for all other gadgets.
This fancy wrist watch will go in a special slot and has a gui. The device is linked to a terminal visa password. It can auto open Security Doors when withing a 3 block distance. Its screen will allow the player to watch through cameras thus allowing the terminal to be placed in a extra more hard to get place. The device only has 1 flaw. Unlike the terminal it has a distance of control [Might change]
