WIRELESS MICROPHONE FOR USE WITH AN IN-CAR VIDEO SYSTEM

摘要

An in-car video system and method is provided where a wireless microphone is configured with bi-directional communications capability. In response to a received RF activation signal, the wireless microphone is automatically switched on to capture (and transmit back to the in-car video system) an audio soundtrack that accompanies the images captured by the car-mounted video camera. A wireless microphone controller mounted in the car transmits the RF activation signal to the wireless microphone. The wireless microphone controller is arranged to transmit the RF activation signal when the VCR starts recording. In an illustrative embodiment of the invention, the wireless microphone receives information, including a confirmation that the VCR is recording, from an RF information signal recieved from the wireless microphone controller mounted in the car. The wireless microphone displays the information to the officer on a display screen. The wireless microphone sounds an audible alert it receives the RF activation or information signals.
