What area is viewed on the sensor screen?
The area found on the screen or footprint is calculated by the height above the ground and lens used. A 10 degree lens at 2,000 ft above ground and pointing straight down can provide a field of view of nearly 200 ft wide. The footprint is changed by adjusting the “look” angle to an oblique view. Animals can be detected from over a mile away and with a footprint width over half a mile.
