Wearable cameras, such as body cameras used by law enforcement officers or action cameras worn by athletes, work by capturing footage through a built-in camera lens and storing the recorded data onto an internal storage device.
The camera lens captures visual information in real-time and converts it into electronic signals. These signals are then processed by the camera's image processor, which applies various algorithms to enhance the image quality and adjust settings such as exposure and white balance. The processed signals are then converted into digital data, which is saved onto the camera's storage medium.
The storage medium in wearable cameras can vary, but commonly used options include internal flash memory, microSD cards, or cloud storage. The camera continuously records footage onto the storage medium in segments or files, depending on the camera's settings. Some cameras also have the capability to livestream footage in real-time to a remote server.
To manage storage space efficiently, wearable cameras may use looping recording, where old footage is overwritten by new footage once the storage capacity is reached. Alternatively, users can manually offload recorded footage onto a computer or external storage device for long-term preservation.
Overall, wearable cameras work by capturing visual information through a camera lens, processing and storing the data onto a storage medium, and providing users with a convenient way to access and manage the recorded footage.
