On a quiet road south of Ventura Boulevard, two cameras on a pole watch over the road, facing opposite directions. A block away, another brace of cameras sit sentry. Together, they constantly film the two points of entry to a closed loop of public streets in Sherman Oaks.
Nearby, on a dual-screen setup in the basement of his hillside home, Robert Shontell pulls up hundreds of snippets of footage captured by the cameras earlier that day. Each shows a car, time-stamped and tagged with the make, model, paint colour and licence plate.
