A camera is auto-focused on an in-person attendee in a meeting who is speaking into a microphone at a live location of the meeting. The live location includes a real-time location system (RTLS) having a RTLS tag and a plurality of RTLS anchors for locating a position of the RTLS tag in three-dimensional space. The RTLS tag is fixed to the microphone and transmits a signal that is received by the plurality of RTLS anchors. In operation, it detected when the microphone is active. The position of the RTLS tag in the live location is then identified in three-dimensional space by using the signal transmitted from the RTLS tag and received by the RTLS anchors to calculate the position of the RTLS tag in three-dimensional space. The position of the RTLS tag in three-dimensional space in the live location is presumed to be the same position as the microphone that the RTLS tag is fixed to. The camera is auto-focused on the identified live location when the microphone is active, the camera thereby outputting a video signal of an area in the proximity of the microphone which is presumed to include an image of the in-person attendee who is speaking into the microphone.
