Relatively speaking, this wearable device is not only portable and easy to use, but also can present the closest display effect. For example, when recording surgery video, it can present the first perspective, so that it can show the most perfect vision when conducting face-to-face and other remote live broadcasts. This effect can be achieved by using the headlight camera system of North and South Electronics. In addition, as a high-value video recording, it is recommended to choose 1080P surgical recording equipment, which can clearly and intuitively show the distribution and agility of each part.
