Panoramic fisheye cameras tutorial and truth.

What are the difference between MWR Panoramic Cameras and others?

​

A.    MWR Panoramic Cameras separate into two different categories:

i. 360∘Panoramic Cameras : For either pendant mounting facing downward or install on floor/ desktop looking up, gathering hemispherical view.

 

ii. 180∘Panoramic Cameras : Majorly wall mounting tilting a bit down or horizontally, gathering hemispherical view with limited vertical angle of view

 

Panoramic Cameras from other manufacturers limited by panoramic de-warping technology mostly have only one type of Panoramic Cameras for both 360∘& 180∘applications.

B. MWR Panoramic Cameras have the same ppf (Pixels per foot, note) but higher

    frame rate than others.

Note:

ppf is the image resolution representation, similar to dpi, please reference ppf definition and examples from below link,

images >60ppf is good enough to identify car license plate & a person’s face, too high ppf (600ppf) won’t be meaningful for surveillance cameras, same as >150 dpi is not necessary for most printers.

Images with same red circle are with the same ppf,

MWR 360∘Panoramic Cameras are with 1:1 aspect ratio, video frame rate is higher than others.

MWR 360∘Panoramic Cameras can be with optional bigger aperture lens (green circle), can even raise the ppf a bit higher by sacrificing vertical height.

C. MWR 1080p/2MP 180∘Panoramic Cameras deliver the same ppf images as

    1920p/5MP 360∘

Panoramic Cameras from others.Only with MWR PanoNVR can de-warp 180∘ Panoramic video with limited vertical FOV, PanoNVR de-warping & ePTZ can handle 180∘Panoramic video with vertical boundaries.  Market available ASIC/software can only handle hemispherical (circle) view.
