When you place an NPC on the map, if you click on him you can see a menu with
properties as an option.
Click properties and you will see the 2 options I mentioned on the left hand side. Change them to 200 or similar to get better viewing distance and angle. You will need to adjust to suit your needs after doing some testing.
FYI: Any character that you add to a map, including the zombie clown, is called an NPC.
