  2. Why would you want a global shutter at 10fps? I would think these things run at long exposure time, so with a relative short read-out, it doesn't really make sense. Unless they expect some high-light condition as well.

    1. Possibly to counter strobing with low frequency light sources?

    2. long exposure times are fine for quasi static scenery like sky observation. but surveillance (civil and military) is an application field that can have high dynamics, e.g. a passing by vehicle (and probably the automotive industry wont abstain joining in...).

    Can someone of PIKSELIM explain how low light level "low-light" is ? Please add some numbers.
    Interesting video : what are those white spots in the top right corner ? Not all RTS pixels I guess, because one of them seems to move a bit to the right. Looks like a airplane ?

  5. Would be more impressive if it was an overclouded, moonless night scene :-(

    1. yes, there is strong moonlight shadow. If you have Sony A7s, then you will turn the night to day in this particular case :)-

  7. Full moon for sure, you can see the shadow of the guy. Full moon imaging is far easier :-)
