The systems and methods discussed herein are directed to presence detection of portable devices of audience measurement panel members, and include a first audience measurement device in proximity to a media device, and a second audience measurement device in the form of a remote control for controlling the media device. The second audience measurement device may receive broadcast identification codes from the portable device of a panel member, and may transmit indicators of received signal strength to the first audience measurement device. The first audience measurement device may similar measure received broadcast signal strength from the portable device, and compare the local measurement and remote measurement to thresholds to determine whether the panel member's portable device is likely in proximity, and thus that the panel member is likely consuming media from the media device.
