The Stealth Sensoring Spell is a spell that detects those under magical disguise. It can be inferred that they act as an invisible force field, which, once penetrated by an intruder, sends a signal to the spell caster. In 1996, Dolores Umbridge cast this around her office.

This spell has an unknown incantation and wand movement (if any).
