The techniques and systems described herein determine whether a computing device is within a particular range to communicate with a monitoring device. If the computing device is within the particular range, the computing device is configured to communicate with the monitoring device via a primary monitoring communication mode (e.g., a radio frequency RF channel). If the computing device is outside the particular range, the computing device is configured to communicate with the monitoring device via a secondary monitoring communication mode (e.g., a Wi-Fi channel or a mobile telephone network MTN channel). The computing device receives, from the monitoring device via the primary monitoring communication mode or the secondary monitoring communication mode, monitoring information associated with a monitored subject (e.g., a baby) or associated with an area in which the monitored subject is located (e.g., a room of a residential dwelling).
