Re: [HH] LibrePlanet 2014 - March 22 23 at MIT

Thanks, Kurt. I found the latter part of last year's panel 2 particularly interesting, specifically the discusion by Rahul Bhattacharyya, Associate Director, Auto-ID Labs concerning RFID tag antenna-based sensing. Took me a moment to discover that one gets to the recording of that full panel

Re: [HH] the missing security camera revolution

In respect to IP POE 3MP cameras currently commercially available for under $200, Hikvision and Dahua both have models that seem well-regarded in respect to hardware. But I don't have a sense of how well-liked their software is; it seems some users pay for Blue Iris or Milestone software instead.

[HH] IOT and LoRaWAN™ (Long Range wide-area networks)

Some items I'm finding helpful while trying to understand this better.. In the first, TI staff criticize LoRaWAN's spread spectrum technology as handling interference far less well than TI's, mostly narrowband, competitive technology.
