This is a great advance. The homeowner is best prepared to evaluate information from the house and the cameras should quickly pay for themselves from the eliminated subscription fees. This also could detect heating system failures, flooding, or even open doors in the middle of the winter.
The one gap I see is to ensure that the systems provide timely alarms while complying with local regulations regarding automatic 911 dialing alarms if the homeowner is not able to access their smartphone and review the alarm data.
This sounds spot on. I have always thought if I could be in control away from my home of the actual 911 call I would feel much better. The one thing that bothers me about this set-up is, what if I have no cell service?
