Ideas in security:
1. Physically secure the device. e.g. clear box, you can’t (within reason) remove it.
2. Trigger an alarm if contact is removed. e.g. alarm switch attached, you will get caught.
3. Destroy the product if it is removed. e.g. clothes ink tags, the value of what you are taking is nothing.
There is physiological reasoning behind each. You can’t easily replace the item. You want a person to be aware of an alarm. It would be easy to disguise or don’t want to stop the person.
