Cameras and angle limits

Hey guys! thanks for all the answers in the other topic, those helped me a lot ;).  I have a doubt, how can I set a min angle and max angle for my camera rotation?

because I don't want my camera to rotate 360° :( . What I tried is to  let a little box to follow the camera and it has a collision with some walls in order to stop showing the part I don't want to. it worked but the effects are really ugly.

That's is solution, as I mentioned It's has some ugly effects and is not always exact.

var prevTarget= jQuery.extend(true, {}, camera.getTarget());

//OP1			 
scene.registerBeforeRender(function () {		            

    for(var i in objs)//the walls I mentioned
	      if (objs[i].intersectsMesh(sphere, true) && scene.isReady()) 
			            	camera.setTarget(prevTarget);               
	      

 prevTarget= jQuery.extend(true, {}, camera.getTarget());
            
});

//or
//OP2 (more precise)
setInterval(function(){

	  for(var i in objs) //the walls I mentioned
			 if (objs[i].intersectsMesh(sphere, true) && scene.isReady()) 
			                camera.setTarget(prevTarget);			            	
			            

	prevTarget= jQuery.extend(true, {}, camera.rotation);
 },0.1);

I hope a better way to do it, thanks guys for supporting us ;)

If you use a rotating camera, for example the angle beta up and down, you can do like this. for alpha you can do the same.

if (camera.beta < 0.1)
     camera.beta = 0.1;
else if (camera.beta > (Math.PI / 2) * 0.92)
     camera.beta = (Math.PI / 2) * 0.92;
