The tutorial references a camera shutter sound to indicate sensor activation, but this isn’t a default asset. If you need one, this looks like a good choice:

Hi Dean,
You’re right, it isn’t the starter content. It is in fact part of the engine content but you have to enable this to find the sound.
In your Content Browser, click on Settings and tick the Show Engine Content checkbox. Onve you’ve done this, you’ll find the Camera_Shutter sound.
I hope this helps.
