When you perform a Wizard’s Sight ritual, choose a square within 20 squares of you, even a square that you can’t see or don’t have line of effect to. You create a magical sensor in that square. You can see and hear as if you were standing there, and you have darkvision through the sensor. Use the Perception skill to determine whether you hear quiet sounds or notice unobtrusive things while observing an area through the sensor. Your Arcana check determines how long the sensor lasts. Focus: A mirror or a crystal ball worth at least 200 gp. The focus conveys what you see and hear.
