A method and system for automatically qualifying a signal reproduction device (18) for installation of mon- itoring equipment (48). In a household in which viewing patterns are to be monitored, for example, a relatively in- expensive and simple set usage device (12) is installed in proximity to a television set (18) which is expected to re- ceive little or no use. Times when the set (18) is in use are sensed (48), and data concerning those times are stored (44) and transmitted (16) to a central location. At the cen- tral location, the times represented by the transmitted data are compared to a minimum usage threshold, and a more sophisticated monitoring device, able to detect the channel tuning state of the T.V. set (18), is installed in proximity to the T.V. set (18) only if the usage of the T.V. set (18) exceeds the minimum usage threshold. The number of rel- atively expensive and complex tuning-monitoring devices required to be installed is thereby reduced.
