- Construct a wireless remote controller mini-toy-car on which mount the camera and the fire extinqguisher.
- Mount fire extinguisher will need some actuator arm to be able to spray and direct the foam in case of fire.
- Both cam and remote toy car will need to have enough batteries or home-in to charging station for replenishment like zoomba vacuum cleaner.
- SMS or email or siren or any combination thereof that can send off notification regarding environment temperature exceeding pre-set level.
- wi-fi Remotely controlled doorlock so in case of fire, neighrborhood or fire enginer personnel can enter withou breaking door.
- Home internet is not perfect and someimes goes offline completely in which case you have to walk up to router to reset it manually. So plug in the router to smart wall socket and schedule 5 minutes of power-off during midnight to reset in case if happens. With that max off-time is a week.
After that I think I can sleep as if I have completely turned off everything.
