Abstract:
1. A proximity-activated voice recording system comprising at least two proximity-activated voice recording devices, each device comprising: at least one of a control system and a wireless transceiver for detecting a proximity defined by a device communications distance; and, an identification token for identifying the voice-activated recording device; at least one of the devices comprising a microphone; and at least one of the devices comprising a speaker for detecting a proximity defined by a vocal communications distance; wherein the system is configured to: detect when two devices are within the proximity as defined by the device communication distance, and then facilitate exchanging identification tokens between the two devices and enable pairing thereof; detect when the two devices are within the proximity defined by the vocal communications distance by receiving an audio test signal sent from the speaker of one of the two devices using the microphone of the other of the two devices; determine that the two devices are within the proximity defined by the vocal communications distance if the audio test signal is successfully received by the other of the two devices, and if so then activate one of the two device to record sounds.
