I would like to make a gear that can see through smoke and it is a handheld device. I would like to click to turn it on and be able to see the screen showing heat signatures like fire or bodies. I would like it to show bodies as red and the rest of the room as black. If you need more information let me know I will try to get back with you.

You can use a BillboardGUI with the AlwaysOnTop property set to true, have one over each Player (Adorned to their Head or Torso Part) and toggle their visibility by setting the Visible property of the Frame Instances in the BillboardGUI.
In short, there is no way to actually render the player's character's "heat signatures" through walls, we don't have special access as Scripters to the ROBLOX renderer - so the best alternative is to use BillboadGUIs - I hope this helps you get it up and running ;)
