Monitoring is the basis of all things done from a distance.  This is the foundation on which other remote capabilities often depend.  Having a monitoring system in place can tell you about outside and inside temperatures, humidity, motion, smoke or fire detection, light levels, and sound.

Knowledge first: well designed monitors will help keep you in the know.  Better than that, you can be alerted remotely when something you care about is changing especially in a way you would prefer it didn’t.
