HD cameras are well known for their wide aspect ratios. However, what if you turned the camera to display a 'tall' aspect ratio instead? What benefits or issues would this create? What, if any, applications might benefit?
In October 2010, Axis announced a feature called Corridor Format that rotates the image from 16:9 to 9:16 aspect ratio in all of its HD cameras. This feature enhancement is predicated on a +/- 90 degree image rotation capability, and yields an image that is taller than it is wide.
We tested the Corridor Format feature using an Axis HD camera and 2 VMS systems.
Inside the Pro section, we examine the Corridor Format feature setup process and installation steps/issues. Further, we compare and contrast the Corridor Format in different VMS systems and show how VMS layout is a key concern. Finally, we demonstrate appropriate and inappropriate use cases for the Corridor Format.
Though not 'gee-whiz' technology, we were pleasantly surprised about the potential for a 'tall' aspect ratio to improve surveillance quality in certain niche applications.
While many cameras support e-flip (or 180 degree rotations), we are not aware who else supports a 90 degree rotation. Feel free to comment on other cameras and we will list them in the report.
