The Remote Video Inspection System (RVIS) was deployed by United States in the late 1990s at select low-traffic border entry points from Canada. The system allowed passport and customs inspections to be conducted remotely, so that low-risk travelers could enter the country during hours that the border station did not have on-site staff. The system was successfully deployed at a number of entry points, in six different states. RVIS was discontinued following the September 11 attacks.
