Evolution 360: Camera Placement and Pixel Density
All camera lenses experience a tradeoff between pixel density and angle of view. This is especially true for hemispheric fisheye lenses where the viewing angle is 180 degrees in every direction.
The fine detail and high pixel count required for facial recognition or license plate reading is limited to close-up views. However, there is a very broad section of the view where detection and identification can occur.
Read the attached Evolution 360 Placement Guidelines to learn about the “4 Zones of Coverage”:
Movement Detection/Situational Awareness
Examples in the guidelines show the pixel densities for two five megapixel Evolution 360 cameras mounted at different heights. The first example is mounted 12 feet high and the second example is mounted at 9 feet high.
Re: Evolution 360: Camera Placement and Pixel Density
Thanks for sharing this article. I have been doing some of this testing myself, and this article outlines the results I found very well. Are there any similar articles that relate to dynamic range and the issues with light and dark areas in the image?
