    Its a wireless camera door bell, called “ring”. No idea if this is real but i assume you could set something like this up to be either motion detection activated(like a mine) or remote activated by looking at the camera feed.

      If you need it remote activated you’d need wifi as well, which makes it kind of complicated to set up with lots of moving parts.

          I can think of about 500 easier ways to do this. I can’t imagine them doing it the complicated way, when the easy way works just as well, costs less, and is less prone to malfunctioning.

          What if the enemy doesn’t come by in the 2 hours the battery would last streaming video this way?

            It doesn’t stream video full time, it detects motion and then let’s you optionally turn on video. (Maybe that changes if you have zonal movement detection but it’s probably locally processed)

          Now you need to somehow power that. Also, how reliable is 3G around the front line, you think?

            Russians deliberately don’t attack telecom infrastructure now, because they did initially before discovering it was actually necessary for their own military comms.

            Mobile routers can last 12 hours and handle a handful of connections, you can probably supplement them with a usb battery bank too.

            Or if there is grid power within WiFi range it’s not an issue. Or there may be more quiescent current models designed for IoT applications (like wind sensors in trees which may have poor signal coverage), I don’t know

        What is hotspot? How does connection form?
