Changing the Standard Camera Height

I've sized up almost all the buildings and doodads in my map a bit and I need to move the standard game camera "back" a bit so game isn't so cramped up on the units. I've never worked with cameras before, so any advice would be grand.

Im not sure if this will work but create a camera the way you want it to be for each player. The have the trigger:

Event
-Every .01 seconds
Action
-Apply camera (name)

Open the Terrrain palete and click the tab at to top and change it to camera, create a camera. Right click on the camera's name in the palete and select edit camra properties. The only real feilds your worried about are:
Angle of Attack-This is th angle the camera is set at(aka at 0 or 360 degrees the camera is parallel to the ground)
Distance to target- how far away the camera is from the unit
Z offset- how far off the ground the camera is

then use the trigger duckduck posted to make the players view the game through the camera. You dont have to make it every .1 seconds it works just fine any time between .5-1 second and that could reduce lag.

Thanks, i'll try that, but do I need to make one camera for each person?
