Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling access to physical areas. One of the methods includes receiving, from at least one of one or more sensors, data identifying a vehicle at a border crossing station, determining current weather conditions for the border crossing station, evaluating whether the current weather conditions are favorable to inspection of the vehicle by a mobile camera, determining that the current weather conditions are favorable to inspection of the vehicle by a mobile camera, and in response to the determination that the current weather conditions are favorable to inspection of the vehicle by a mobile camera, providing at least one of one or more mobile cameras with instructions to cause each of the at least one of the mobile cameras to inspect the vehicle.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling access to physical areas. One of the methods includes receiving first data, determining, using the first data, whether each of the passengers for a vehicle is authorized to cross a border, storing second data in a data set of pre-registered border crossers, receiving third data identifying the vehicle and indicating entry of the vehicle into a border crossing station, comparing the third data with data from the data set of pre-registered border crossers, determining that the third data and the second data both identify the vehicle, collecting, for each current passenger in the vehicle, fourth data representing the current passenger, determining whether the current passengers in the vehicle and the passengers identified in the second data are the same people, and providing instructions to guide the vehicle to a lane at the border crossing station.
