I wonder what your cost to develope this will be?
What is the cost of the camera equipment?
This may be one of those great ideas but too difficult or costly to build.

Moller is probably the world formost expert on vertical take off, hovering and landing in one piece...
The areobot will be used to inspect high tension power lines over unimproved locations with video.

Keep us posted as this is a really cool project.
