The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
The prevalence of video surveillance in the UK is often overstated due to unreliable estimates being requoted; [50] [51] for example one report in 2002 extrapolated from a very small sample to estimate the number of cameras in the UK at 4.2 million (of which 500,000 were in Greater London). [52]
A miniature UAV, small UAV (SUAV), or drone [1] is an unmanned aerial vehicle small enough to be man-portable. Smallest UAVs are called micro air vehicle . Miniature UAVs range from micro air vehicles (MAVs) that can be carried by an infantryman, to man-portable UAVs that can be carried and launched like an infantry man-portable air-defense ...
