That is sorta similar to how the found the Idaho shooter yesterday. I read that they monitored cell phone activity and looked for signals which were stationary which lead them to his location.
I have a few of those Revo's which have been working great for years in Blueiris.
I would never take a chance on an update which could render them useless.
Looks like a wireless access point which would keep them from having to run an ethernet cable to that camera. The AP and camera would still need electric to the location.
The FBI has reverted back to 9mm from 10mm as they say the 9 gives less kick and faster to load but I know the real reason is that the 10mm are too easy to loose, just like our sockets.
For over 50 years, I have painted all metric wrenches and sockets RED for quick reference amongst the SAE tools. The exception is the 10mm are painted YELLOW as they are used the most.
I like the setups that Pawtropolis has using Blueiris. That link is to their west operation. Here is a link to their East store.
