Simple Toggling 1st person camera script

I wrote a simple script using the camera system that when you say "/2 front cam" it goes into an interactive first person view, and when you say "/2 normal cam" it goes back to normal. This is very simple, so I wont leave any license or something like that. Here it is

camera() 
{ 
    llSetCameraParams([ 
        CAMERA_ACTIVE, TRUE, 
        CAMERA_POSITION, llGetPos(), 
        CAMERA_DISTANCE, 0.0, 
        CAMERA_POSITION_LAG, 0.0, 
        CAMERA_POSITION_THRESHOLD, 0.0, 
        CAMERA_BEHINDNESS_ANGLE, 0.0, 
        CAMERA_BEHINDNESS_LAG, 0.0, 
        CAMERA_FOCUS_LAG, 0.0, 
        CAMERA_FOCUS_THRESHOLD, 0.0, 
        CAMERA_FOCUS_OFFSET, <1,0,1> 
    ]); 
} 

default 
{ 
    state_entry()
    {
        llClearCameraParams();
        llListen(2,"",llGetOwner(),"");
     
}
    listen( integer channel, string name, key id, string message )
    {
        if (message == "front cam")
        {
            llRequestPermissions(llGetOwner(), PERMISSION_CONTROL_CAMERA); 
            llOwnerSay("1st person camera activated");
                }
            
        
    if (message == "normal cam")
    {
        llOwnerSay("Camera back to normal.");
        llClearCameraParams();
        llResetScript();
    }
}
    run_time_permissions(integer perm) 
    { 
        if ((perm & PERMISSION_CONTROL_CAMERA) == PERMISSION_CONTROL_CAMERA) 
        { 
           camera();  
        } 
    } 
}
