Stop the Camera at Bounds?

Hey Guys, been working on an top down game, specifically the camera. I'm using the observer camera to navigate around my world but the biggest problem I have with that is I can't for the life of me figure out how to clamp it inside a specified area/zone/cords.

I got the point where I tried to remake the camera movement which (sort of) works but comes with undesired stuttering which is due to the fact I'm literally updating the position of the camera by a small value. Then on top of that its very slow movement to negate the stutter.

Awful unrefined code below, I've attempted to 'smooth' it out using a for loop but now realizing the loop actually applies all of the updates at once (Or so fast it doesn't matter).

//binds.cs
function moveleft(%val)
{
%addx = -0.25;
%addy = 0;
%addz = 0;

if(%val == 1)
{
$moving = true;
commandToServer('MoveCamera', %addx, %addy, %addz);
}
else
$moving = false;
}

//Commands.cs
function serverCmdMoveCamera(%client, %addx, %addy, %addz, %camera)
{
%camera = %client.camera;
//%camera.position = VectorAdd(%camera.position, %addx SPC %addy SPC %addz);
//echo(%client SPC %addx SPC %addy SPC %addz SPC %camera);
if($moving == true)
{
moveCameraDirection( %client, %addx, %addy, %addz, %camera );
//schedule(1, 0, "moveCameraDirection", %client, %addx, %addy, %addz, %camera);
}
else
return;
}

function moveCameraDirection(%client, %addx, %addy, %addz, %camera)
{
%x = %addx / 30; //30 for 30 FPS?
%y = %addy / 30;
%z = %addz / 30;
//echo("Woop: " @ %x SPC %y SPC %z);
for(%i = 0; %i < 30; %i++)
{
//echo("Pos " @ %camera.position);
%camera.position = VectorAdd(%camera.position, %x SPC %y SPC %z);
//%i++;
}
//echo(%camera.position);
commandToServer('MoveCamera', %addx, %addy, %addz, %camera);
}

Ideally I'd like to use the movement that's already applied through $mvLeftAction that just stops at at defined position but I don't know how to do that while the moveLeft button is being held.
