Corridor viewing is one of the subtler difficulties in surveillance. You wouldn’t think it just by looking at it – a hallway is a hallway is a hallway, right?

Corridor viewing is one of the subtler difficulties in surveillance. You wouldn’t think it just by looking at it – a hallway is a hallway is a hallway, right? But many cameras require a little bit of tinkering to better handle the problem of halls being halls, that is to say, halls squeezing the viewable image with walls.

Walls provide a sort of visual redundancy when viewed with a camera’s ordinary landscape setting. In offices, this crowds the image, making visible objects of interest harder to detect. The same applies to virtually any sort of ‘hallway’ type setting you can think of – tunnelworks, stairwells, narrow roads, even runways! The redundancies and empty space wastes the security cameras strength. It can needlessly sap the quality of night time picture by spending too much IR strength whitening up the walls, giving the image a very washed out look. The empty space is empty, but it won’t be when it hits your video recorder, pointlessly taking up storage space. Basically, corridors suck. They’re boring and they’ll kick your surveillance system right in the pants if you let them.

Axis’s Corridor Format is a pretty simple solution to a seemingly simple problem capable of producing bigger issues. What the technology does is pretty terse in its function – it swaps the usual 16:9 video format into a 9:16 format. So instead of landscape, it goes vertical, that dreaded recording angle of choice for YouTube cellphone videos. Except this time it’ll be exactly what you want.

How is this done? Time to blow your mind: install the camera sideways, and then rotate the viewable image 90-degrees in the Axis video management software! Okay, we’re underselling it. Rotating live recordings actually requires a fair bit of processing power. Once again, Axis’s software developers have helped ease the pain in this by smoothing out the processing requirements. What you end up with is a crisp image that isn’t a drain on your processing power while at the same time maximizing actual image quality!
