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.
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
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.
