  Security surveillance is one of the most important issues in smart cities,
especially in an era of terrorism. Deploying a number of (video) cameras is a
common surveillance approach. Given the never-ending power offered by vehicles
to metropolises, exploiting vehicle traffic to design camera placement
strategies could potentially facilitate security surveillance. This article
constitutes the first effort toward building the linkage between vehicle
traffic and security surveillance, which is a critical problem for smart
cities. We expect our study could influence the decision making of surveillance
camera placement, and foster more research of principled ways of security
surveillance beneficial to our physical-world life. Code has been made publicly
available.
