This was in some of the mainstream tech news today. A startup called Kangaroo has launched a DIY security system based on $30 battery powered wifi PIRs with no hub and professional monitoring for $60/year (or self monitored for $1/month).
It strikes me as an odd but interesting move compared to a lot of the DIY security systems out there which are panel/hub based, but it seems quite limited considering there are literally no other sensor types available (no door contacts or glass breaks, for example) and no option for video which is common in systems like Nest Alarm.
What do you think of the no hub/panel approach coupled with cheap professional monitoring? I'm not convinced Kangaroo itself is headed for great success, but the decentralized approach seems to be catching on with things like Apple Homekit increasing in popularity.
