While wielded it reveals the estimated positions of nearby motion sources, in a similar way as hearing does, but with some better precision and range.
Useful against feral predators hiding in bathrooms[/quote]
Seems a little too much like the scanner out of Alien.
I think motion detectors would be cool, but they’d be better suited for perimeter defense. If you place down a motion sensor, and set it to a certain “channel” (when you hit activate, it’d ask you where you wanted to place it and what channel you wanted to set it to, maybe out of 1000), you could go into a control room and access the detectors.
Motion detectors without stationary scanners aren’t really based in fact afaik.
I recently did a project in my physics class where me and a buddy tested the range of a stationary motion detector. He was holding a 2x2 piece of cardboard to make a better target for the detector, but even then, it stopped picking his motions up at about 15 meters. Even factoring in the inevitable technology advances between now and the 2040s, I doubt a handheld motion detector would be able to pick up movements through solid walls, which would kind of make the thing useless.
tl;dr - handheld motion detectors kind of silly, stationary ones would be cool.[/quote]
I also thought they were far off in the realm of fiction, but some quick googling found a device called the The RANGE-R, which if legit, is supposedly able to detect human breathing through walls from a distance of up to 50 ft.
Far of from the alien franchise motion detection tech, but it IMO could work as enough justification, if it’s real tech of course.
Anyhow I think stationary sensors could work.
And technically speaking there’s nothing stopping you from linking the alarm system to a tablet pc and then throwing the usually stationary detectors around to get some crude “motion detecting grenades”. Don’t know if those would be useful once you consider the limitations though.
