HD 'widescreen' aspect ratios are increasingly becoming the norm for video surveillance cameras, with 720p HD, 1080p Full HD and now 4K Ultra HD.
The wide format can be very useful in many surveillance scenarios but some of them fit poorly.
The most commonly cited problem are hallways which are tall and narrow, fitting poorly in widescreen as shown below:
In this report, we tested corridor mode in a number of scenarios, starting with hallways.
We also tested vehicle entrances / license plate capture like so:
Finally, we tested perimeters / building exteriors like so:
In the past, corridor mode availability was limited, but with more manufacturers including such image rotation in their cameras, IPVM has a comprehensive report covering the below questions:
- Where is corridor mode most beneficial?
- Does image quality remain similar after rotation?
- What manufacturer support is there for corridor mode, in either cameras or VMSes?
- What are benefits/tradeoffs between 9:16 and 3:4?
- Where are the options to rotate camera images to corridor mode?
