How to shake our camera?

Hello, I'm new here, I want to ask about how it is any possibilities to shake our camera/view? For example in FPS game like call of duty when the enemy shoot hit the player then the camera shake. Secondly, how to make our camera blur/motion blur effect?

 

Making the camera do motion blur would require the pro license.

Making it shake, however, is easy. One way to do it:

Code (csharp):

1.  
2. var shakeFactor = Quaternion.FromToRotation(Vector3.forward, Vector3(Random.Range(-1.0,1.0),Random.Range(-1.0,1.0), 10));
3. CameraObject.rotation *= shakeFactor;
4.  

Someone will probably post a simpler way. I suck at Quaternions.
