Factual error: Throughout season 2 there are a few shots taken of buildings with PTZ style surveillance cameras attached to said buildings. PTZ cameras are the ones with an arm and a ball with a black lens spanning 360°. This show takes place in 1992, and from what limited dates as to surveillance camera creation I could find, PTZ cameras were not available until the 2000's. In 1992 the large blocky ones were only available with terrible resolution.
