The Sony VCT-HSM1 Helmet Side Mount allows you to attach your action cam
on the side of any standard helmet, such as a motorcycle or football
helmet. It features a curved surface mount that matches the oval shape
of a helmet, and as a precaution, it uses a safety leash and buckle lock
to secure the camera in case of unexpected accidental dismounting of
the camera. The camera mount angle is adjustable, so you can position
the camera as you see fit. All standard mount action cams are supported.
