That is a good post and I hadn’t heard of the T2S+ before. But it costs $300+ and is around 50K pixels (256x192). I see that an 160x120 FLIR Lepton module is $184 these days (Digikey). So this new stuff is competitive but not revolutionary imho. It’s good that the FLIR monopoly is finally broken though. All that existed earlier other than FLIR was very low res devices.

Thanks, it’s late here now but I’ll try to look soon. I didn’t realize significant improvements over Goldberg etc al were really possible. I’ll try to understand that too.

Is there another post somewhere giving a general description of what you are doing?

Do you have a link about your messaging app? And PIR doesn’t conceal the existence of traffic, so it doesn’t seem like the right thing for messaging. It’s more for databases as the name implies. What exactly are you trying to do?
