Unity Engine

SORRY FOR MY BASIC ENGLISH
i do not know the player does not react well when i move to the other side.
When press “A” the player move’s -X
“D” move’s +X
Can’t find the error!!!
I think is the camera.
Heres a video: http://1drv.ms/1OEYwFf

Pd: i use this part of code in the PlayerController script
if (GetComponent ().velocity.x > 0) {
transform.localScale = new Vector3 (1f, 1f, 1f);
}
else if (GetComponent ().velocity.x < 0){
transform.localScale = new Vector3 (-1f, 1f, 1f);
}
