In many surveillance situations you want to monitor an area that is
more vertical than horizontal in shape. This includes staircases,
hallways, aisles, roads, runways, tunnels, and many other applications.
In these situations, the traditional landscape format is not the optimal
solution since it creates video streams where a large part of the field
of view – specifically the sides of the image – is redundant.
Axis’ unique and simple solution to this problem is the corridor
format. The new format allows you to get a vertically oriented,
"portrait"-shaped video stream from the camera. The video is adapted
perfectly to the monitored area, maximizing image quality while
eliminating bandwidth and storage waste.
Corridor format is even more useful for modern HDTV network cameras
that deliver a 16:9 aspect ratio since the resulting image will have a
9:16 aspect ratio – just the right thing for narrow corridors, hallways
or aisles.
