Garage door opener monitor providing status warning on TV or computer display signal

摘要

A system for monitoring a movable barrier in which a small receiver box (108) is wired in line between a television signal source (106) and a television monitor (110). When the receiver box receives a signal from a garage door operator (104) mounted near the garage door, a small icon is displayed in the corner of the television indicating that the door is open. This will place an indication of the status of the garage door right where many people are looking. Advantageously, many people watch television before going to bed and having an icon displayed exactly where they will be looking before falling asleep can help increase home security.
