Camera is the basic component of wearable mobile devices. Because of its small size.

Wearable motion of camera components is the most basic. Small size, can be used at any time. In theory, wearable computing devices allow users to keep the camera shooting and even record everything that is automatically uploaded to the cloud. Obviously, there are many security risks. Cameras in wearable computing devices can not only record detailed logs of users' daily lives, but also record unauthorized behaviors of others. This behavior completely violates privacy ethics.
