Portable digital video camera configured for remote image acquisition control and viewing
A wearable digital video camera ( 10 ) is equipped with wireless connection protocol and global navigation and location positioning system technology to provide remote image acquisition control and viewing. The Bluetooth® packet-based open wireless technology standard protocol ( 400 ) is preferred for use in providing control signals or streaming data to the digital video camera and for accessing image content stored on or streaming from the digital video camera. The GPS technology ( 402 ) is preferred for use in tracking of the location of the digital video camera as it records image information. A rotating mount ( 300 ) with a locking member ( 330 ) on the camera housing ( 22 ) allows adjustment of the pointing angle of the wearable digital video camera when it is attached to a mounting surface.
