Nice work. Looks like it tried to engage the falling debris too. There was a version with stinger, but I'd love to see mistral integrated in the same way as it's advertised for counter missile work as well as part of the simbad system

Accidentally stumbled on a pre war video of a Russian drone manufacturer workshop. The interesting part for me was the use of commercial sony cameras, which was something of a curiosity and was widely mocked as some sort of stone age engineering, but you can see the same commercial cameras used by considerable number drone manufacturers both civilian and military.
Basically, the story of how and why use a consumer-grade photo cameras is that it's a consumable part. Depending on the model they say the life cycle is about 100.000(Sony Nex- line) to 500.000(Sony RX line) pictures , the reason is the shutter mechanism life cycle which is the case even with expensive non-consumer cameras , that is why the consumer-grade cameras are the prime choice offering more than enough resolution (RX1II is at something like 46mega pixel) for smaller size drones, in regular service they say camera takes 7000+ high definition pictures per 2-3h flight and drone is meant to be used for about 8-12h daily, so the many cameras last about a month of every day drone operation before the shutter is toast. (in war time drone itself probably doesn't last a month anyway) Cameras are tuned to photograph at certain frequencies depending on flight speed or take a video , focus distance is fixed for a specific flight height.
Claimed shutter life cycles
Sony Nex-series 70-100.000 pics
Sony Alpha series - 200.000 picts
Sony RX1 series - 500.000 picts
As you can imagine photos taken are not the video live stream but for post flight analysis , where they use collating software that stitches the pics together and if same area is patroled can mark the changes from flight to flight.
A commercial drone used for mapping etc. They explain the camera options on the website , note exact same cameras as those used in Russian drones. Of course as the drone is probably not used as much as in miltary service, so a camera might last much longer.

Thats a fascinating explanation; it had never occurred to me that the shutters on cameras wear out, but now hearing that of course they would, just like any other machine.

From what I've heard from my friends who are into photography, most consumer cameras these days are intentionally built with a limited life span for only a casual use. So anyone who'd want or need to take lots of pictures is forced to buy a "professional" grade camera which, obviously, is much more expensive.

I hate that school of design. 'Planned obsolescence' is the official term - very maddening and widespread. This would be a subset of that 'contrived durability,' which as you say is deliberately designing something to wear out.

I wonder whether this also effects cell phone cameras? I've had my 6S now since 2015, and lately it seems the photos are less sharp / slower to capture. But that could just as easily be the phone getting old.
