So it should wait for a 'predetermined time' of no motion before raising the alarm....how long? 10 minutes? 20 minutes? So basically an ambulance response time or two then.

Recording motion and correlating with previous routines is a powerful method because it allows 'soft' inference techniques to be used, which are much more likely to give the correct answer than a simple binary time delay metric.

I think that the privacy issue is a red herring in this case. Protection schemes based on this technology would be opted into and operated by private companies regulated by the Data Protection Act.

Plus I'm sure a very strong point of the business case would be that the data chould be kept in an anonymised form and only interrogated by the algorithms doing the motion correlation.
