How To Use

Tier 1 is the only non-placeable DOTs projector since it's a Laser Pen. But the other two are placeable. What you want to do is place them in the Ghost's Favourite room and wait. Soon you will see a ghost walking through as a white figure. (Use the image gif as example)
Tier 1 the ghost will come towards you. It's easier to see with the lights off (Tier 1 Requires it) but you can see with the lights on (Expect for Tier 1)

Usage

Tier 1: Hold and wait. Walk around the room and wait for the ghost to walk in the path. (As a white transparent figure)
Tier 2 & Tier 3 is place and wait. Tier 2 requires to be placed on Floor for the best use and Tier 3 on the wall for the best effect.

Tips & Strategy
