I don't think that's really needed in this case, however, because:
1) We do have radar now and human visual tricks don't really matter to it, and
2) Purely optical detection is still trivial for non-humans, this hits exactly one intended blind-spot tuned just for us.
This is a one-trick pony, albeit that trick is very cool if you happen to be a deaf human without access to a variable frame rate camera (e.g. any cheap modern phone), and the payload isn't subject to being centrifuged into oblivion. Most small mammals will still see it just fine; cameras running at a multiple of its rotation rate will see it as a stable if somewhat blurry image. And a high enough shutter speed (given enough light) would just plain show it as it is.
For spying on protestors in a noisy urban environment - This is perfect. Against any military targets with better tech than longbows and armored cavalry, not so much.
