The Hindsight 2020CAM system can respond to external events by making a video clip event automatically using the external trigger known as the process interface unit (PIU). Events can be triggered manually by using the PIU box or by using the wireless keyfob remote to trigger the event.
The PIU control can also accept signals from a PLC control system, process upset sensor, or vision analysis system. External events are signaled to the 2020CAM Engine by a dry contact closure, such as a relay. This allows for automated saving of video clips from the 2020CAM’s continuous video buffer for archiving and frame-by-frame analysis.
