/ Camera Housing
Your HERO4 Silver camera comes with three types of backdoors:
Standard Backdoor, Skeleton Backdoor and Touch Backdoor.
The Standard Backdoor makes the housing
waterproof to 131' (40m). Use this door when you
need to protect the camera from water, dirt, sand
and other environmental hazards.
The Touch Backdoor (waterproof) lets you use the
Touch Display and provides waterproof protection
to 10' (3m).
The Skeleton Backdoor (non-waterproof)
provides better sound quality by allowing more
sound to reach the camera's microphone. It also
reduces wind noise at speeds up to 100mph when
mounted on helmets, motorcycles, bikes and
other fast-moving vehicles. Use this backdoor
only when sand, excessive dirt/dust and water
damage is not a risk. This backdoor is also
recommended for use inside vehicles.
