A Short History of the Central Station was put together for training by Jon Sargent in 1999 using very old historical slides, public domain photos, and older alarm company-provided pictures including some from National Guardian's Western Monitoring Centers. The ending part was a video for customers from Security from Ameritech, showing their state of the art monitoring at that time.
