Known Bugs:
*Using water arrows while in noclip will not change the camera sounds
*Camera detects the player too easily
	- even a foot is enough
	- even in complete darkness
*The only way to avoid an alarm after being sighted is to hide behind an object or leave the camera's field of view
*Couldn't find any way to disable the func_securitycamera. i.e. 'Remove' will also delete the model, tubes etc.
