Methods, apparatus, and systems are disclosed to collect impressions associated with over-the-top media devices. An example apparatus includes memory; and at least one processor to execute instructions to access a first request, the first request from a user-controlled client device, the first request including an over-the-top device identifier that identifies an over-the-top device that presents media, in response to determining a user of the user-controlled client device is a panelist of a first server, store the over-the-top device identifier with demographics corresponding to the panelist, access a second request, the second request from the over-the-top device, the second request including the over-the-top device identifier and a media identifier, and log an impression associated with the media identifier and the demographics, the impression corresponding to the panelist of the first server.

In one aspect, a method is described. The method includes detecting a first data packet transmitted through a wide area network (WAN), the first packet representing media presented at a client device of a plurality of client devices at a media exposure measurement location, each client device having a respective device identifier; detecting, within a monitoring interval, one or more second data packets transmitted through a local area network (LAN), each of the one or more second packets specifying a candidate device identifier, where the monitoring interval comprises a time window from the detection of the first packet; generating a score for each candidate device identifier based on a number of the second packets detected within the monitoring interval; based on the score, selecting, from the candidate device identifiers, a target device identifier; and storing data correlating the first packet with the target device identifier.
