Driver Specific settings

Movement limits: These limits indicate the end positions in all directions; i.e. left, right, up and down. The limits will assure that the head is kept within certain bounds. Use if there is any obstructions to head movements.
Zoom limits: These limit indicates the end position for focus and zoom. In order not to stall the motors when approaching the mechanical end positions of your lens, it is very important that you limit the wide/tele interval in accordance.
The Trippy uses feedback pots to report the position of the Zoom back to the head, in some cases the full mechanical and electrical span of these pots are not used. This means that even when the Zoom has reached its mechanical limit the head still tries to drive the Zoom further because the pot reports the position incorrectly. Most lenses has a mechanical power cut-out switch that prevents damage to the motors from trying to drive the lens past its mechanical limits but some do not have this feature which means that you may damage the lens if you set the values incorrectly. To set these values for Zoom follow this procedure:
  1. Set the Wide value to 3000 and the Tele value to 4000 (these are the default values).
  2. Send the zoom to max wide with the CGI-command "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=1".
  3. Now decrease the Wide value by 200.
  4. Again send the zoom to max wide with the same CGI-command as in step 2 "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=1".
  5. If the zoom moved repeat steps 3 and 4, if not go to 6.
  6. Send the zoom to max tele with the CGI-command "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=9999".
  7. Now increase the Tele value by 200.
  8. Again send the zoom to max tele with the same CGI-command as in step 6 "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=9999".
  9. If the zoom moved repeat steps 7 and 8, if not go to 10.
  10. Done.
Zoom enabled: If you do not have a zoom lens uncheck this box in accordance.
Optical data: The MaxDeg setting should correspond to the view angle at max wide, the MinDeg setting should correspond to the angle at max tele. Follow this procedure to set these values:
  1. Click the Home button.
  2. Send the zoom to max wide with the CGI-command "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=1".
  3. Click a point in the image on the pan axle (click to the left or to the right of the center only, not over or under).
  4. If the camera moved to far, decrease the MaxDeg value, if the camera moved to short increase the MaxDeg value then go to step 2. If the point you clicked centered correctly, continue to step 5.
  5. Send the zoom to max tele with the CGI-command "http://<videoserver name>/axis-cgi/com/ptz.cgi?camera=<cam nbr>&zoom=9999".
  6. Click a point in the image on the pan axle (click to the left or to the right of the center only, not over or under).
  7. If the camera moved to far, decrease the MinDeg value, if the camera moved to short increase the MinDeg value then go to step 7. If the point you clicked centered correctly, continue to step 8.
  8. Done.
Flip Pan: This checkbox mirrors movement for the pan axle.
Flip Tilt: This checkbox mirrors movement for the tilt axle, use if PTZ is mounted upside down.
