Hessdalen - Step1 - Drawing of the camerasystem.


The new device is the video-timedelay and the date and the new version of the "date and time on videosignal"-equipment.

Most of the sightnings done by the exixting equipment is over before the video-recorder has started. It uses around 5 seconds to start, depending of the previous state. The SGI-computere uses 1 second to analyse the picture. It we put in a timedelay for the video-signal, which is more than these 6 seconds, we will get all sightnings, the SGI-computer do, on to the tape.

The new "date and time on videosignal"-equipment is needed whenever there will be more cameras in Hessdalen. All cameras have to have a timesignal on the tape, so we can compare the different tapes. We need then a date and time system which have a master clock, so that the timesignal on each camerascreen is coming from the some main clock. The system that is installed today, do not have that possibility.
