As part of the evolution of SpectraMesh and what I've been using it for, I realized I've got a few standalone sensors (as well as MANY portable sensors) that give useful info, but none of it was being used efficiently. Instead of having to remember to check a bunch of sensors, I decided it'd be much more useful to have a single interface that will give me all of the info I need. Even better, if I'm merging sensor data together I can do further analysis on it and start to track patterns.
Enter Steadfast Crypt.
Steadfast Crypt is a purpose built surveillance detection network, using a network of sensors connected together via SpectraMesh datalink. The sensors detect BLE and WIFI devices and scan for things like Ring doorbells, airtags, Alexa devices, drones, and even axon body cameras. It compares newly seen devices against a baseline of known devices (and yes, I can set a device as known so it is added to the baseline) - and if it sees something that is potentially concerning it sends me alerts. These alerts show up on my various handheld devices, but also on the clock in my office that has a notifications API built into it to allow for exactly this.
The idea is to gain situational awareness of what exists around me, so that I can tailor activities appropriately. This allows me to know if drones are flying by, police are hanging out nearby, or my neighbor installs a new Ring doorbell - with proactive alerting and notifications.
I'm still fine tuning the detection engine and building out the service - but it's already been great at finding things I didn't know about, like a low cost IP camera a neighbor has that I was completely unaware of.
