No motion detected

I would like to suggest a new feature using the indoor cameras and motion detectors.As well as detecting motion when there shouldn’t be any, they could be used, when the system is set to “Home”, for detecting when there hasn’t been any motion within a parameterised time span. When this is detected it could trigger an automatic alarm call to a shared user’s mobile phone.As an example, I live alone and if I fell down stairs and was unable to get to my phone, this feature could save time in my being discovered.
