I'm not sure if you mean something different, but there is already
a large network of people recording meteors with video cameras, and
they are providing valuable information for meteorite orbits, as well
as location of meteor falls. At a meteoroids meeting I went to four
years ago, there was even a lecture for the video observers giving
advice for how to record 'calibration' images of 'fixed locations'
such as lampposts, houses and storefronts so that the measurements
could be made more accurate.

Some extra information. I didn't see house-type 'reference objects'
in the next links, however references like that is described in the
last link of the story of the Spain bolide.

.. describes in detail the collection of observations,
including the video recordings of a group of university
students who had been having a party on an open terrace,
which provided a directional orientation and a valuable
record for the object's orbit determination and fragmentation.)
