Wireless event authentication system |
摘要 |
A wireless data acquisition and recording (DAR) system includes acquisition circuitry including a video camera and/or a microphone carried by an operator for capturing video and audio events viewed and/or heard by the operator. A wireless transmitter wirelessly transmits digital signals containing the video events captured by the video camera and the audio events detected by the microphone. A data display and report submission (DD) device receives the wirelessly transmitted digital data captured by the acquisition circuitry and stores the data as media files.
