Abstract
Described implementations utilize existing power lines at a location to detect and monitor the presence, position, and/or identity of users at the location. Rather than requiring dedicated monitors within each room or position within the location, the described implementations monitor a baseline voltage signal and/or an introduced voltage signal on the ground line of an existing power line of the location to determine the presence, position, and/or identity of a user at the location, either alone or in combination with other information.
