| Zusammenfassung: | Methods and systems are described for monitoring a monitored space. An example computer-implemented method for monitoring a monitored space includes periodically emitting with an active infrared sensor a modulated infrared signal into a monitored space being monitored by a home automation system, receiving with the active infrared sensor the modulated infrared signals reflected from objects in the monitored space, and determining at least one of whether a number of objects in the monitored space have changed and whether any of the objects are moving. |
