Arcane Camera

When you cast this spell you hold the Prism and receiver in your hand, upon completing the spell you place the prism within 10 feet of a solid object the direction it is facing becomes the direction the camera is looking. the prism floats in the position. The prism stays there for the next 24 hours recording all that it sees to the receiver at the end of the spell the prism floats gently to the ground if it can. 

At any point in time, the holder of the receiver can review the footage currents sightline, and by thinking of a time between the casting ad the present can see what the prism saw at that time.  If the one holding the receiver knows minor illusion, minor image, or major image they can project a larger image of what the receiver is showing. 

The prism and the receiver cannot be moved more than 500 ft apart or their connection is severed and the spell has to be recast to connect them. The receiver must also be in the same plane as the receiver else the connection is broken.
