A key problem in widely distributed camera networks is geolocating the cameras. In this work we consider three scenarios for camera localization: localizing a camera in an unknown environment using the diurnal cycle, localizing a camera using weather variations by finding correlations with satellite imagery, and adding a new camera in a region with many other cameras. We find that simple summary statistics (the time course of principal component coefficients) are sufficient to geolocate cameras without determining correspondences between cameras or explicitly reasoning about weather in the scene.
